The sterile insect technique (SIT) may offer a means to control the transmission of mosquito borne diseases. SIT involves the release of male insects that have been sterilized by exposure to ionizing radiation. We determined the effects of different doses of radiation on the survival and reproductive capacity of local strains of Aedes aegypti and Ae. albopictus in southern Mexico. The survival of irradiated pupae was invariably greater than 90% and did not differ significantly in either sex for either species. Irradiation had no significant adverse effects on the flight ability (capacity to fly out of a test device) of male mosquitoes, which consistently exceeded 91% in Ae. aegypti and 96% in Ae. albopictus. The average number of eggs laid per female was significantly reduced in Ae. aegypti at doses of 15 and 30 Gy and no eggs were laid by females that had been exposed to 50 Gy. Similarly, in Ae. albopictus, egg production was reduced at doses of 15 and 25 Gy and was eliminated at 35 Gy. In Ae. aegypti, fertility in males was eliminated at 70 Gy and was eliminated at 30 Gy in females, whereas in Ae. albopictus, the fertility of males that mated with untreated females was almost zero (0.1%) in the 50 Gy treatment and female fertility was eliminated at 35 Gy. Irradiation treatments resulted in reduced ovary length and fewer follicles in both species. The adult median survival time of both species was reduced by irradiation in a dose-dependent manner. However, sterilizing doses of 35 Gy and 50 Gy resulted in little reduction in survival times of males of Ae. albopictus and Ae. aegypti, respectively, indicating that these doses should be suitable for future evaluations of SIT-based control of these species. The results of the present study will be applied to studies of male sexual competitiveness and to stepwise evaluations of the sterile insect technique for population suppression of these vectors in Mexico.

Resumen en inglés

Aedes aegypti is a major vector of arboviruses that may be controlled on an area-wide basis using the sterile insect technique (SIT). Larval diet is a major factor in mass-rearing for SIT programs. We compared dietary effects on immature development and adult fitness-related characteristics for an International Atomic Energy Agency (IAEA) diet, developed for rearing Ae. albopictus, and a standardized laboratory rodent diet (LRD), under a 14:10 h (light:dark) photoperiod ("light" treatment) or continuous darkness during larval rearing. Larval development was generally fastest in the IAEA diet, likely reflecting the high protein and lipid content of this diet. The proportion of larvae that survived to pupation or to adult emergence did not differ significantly between diets or light treatments. Insects from the LRD-dark treatment produced the highest proportion of male pupae (93% at 24 h after the beginning of pupation) whereas adult sex ratio from the IAEA diet tended to be more male-biased than that of the LRD diet. Adult longevity did not differ significantly with larval diet or light conditions, irrespective of sex. In other aspects the LRD diet generally performed best. Adult males from the LRD diet were significantly larger than those from the IAEA diet, irrespective of light treatment. Females from the LRD diet had ~25% higher fecundity and ~8% higher egg fertility compared to those from the IAEA diet. Adult flight ability did not differ between larval diets, and males had a similar number of copulations with wild females, irrespective of larval diet. The LRD diet had lower protein and fat content but a higher carbohydrate and energetic content than the IAEA diet. We conclude that the LRD diet is a low-cost standardized diet that is likely to be suitable for mass-rearing of Ae. aegypti for area-wide SIT-based vector control.

Resumen en español

La Bahía de Chetumal, en el Caribe Occidental es considerada uniformemente hiposalina y oligotrófica. Para definir si la biomasa de zooplancton muestra un comportamiento homogéneo en este sistema costero se analizó la variación temporal y espacial de este parámetro (peso húmedo: mg m-³) durante dos ciclos anuales (1996, 1997). Se obtuvieron muestras bimensuales en las épocas de nortes, secas y lluvias. Durante 1996, la biomasa anual promedio (11,56 mg m-³) fue significativamente menor a la de 1997 (16,18 mg m-³). Se observaron biomasas ligeramente mayores durante nortes en ambos años, seguidas por secas y lluvias, lo que sugiere una estacionalidad en el comportamiento de este factor de la comunidad del zooplancton. Las variaciones mensuales también fueron considerables y sugieren que podría haber cambios importantes a escalas menores a la estacional o interanual. Entre el 45 y 51% de la biomasa en 1996 y 1997 se distribuyó en las localidades más externas y salinas de la bahía independientemente de la época. La alta producción primaria que usualmente se asocia a la zona interna de la bahía no se reflejó en la biomasa del zooplancton, lo que se atribuyó a las limitaciones en la distribución local de los herbívoros del zooplancton residente y posiblemente a la hipoxia relacionada con eutrofización local. Las diferencias interanuales, con mayores valores de biomasa, temperaturas y salinidades en 1997, así como la débil estacionalidad de ese año (nortes) podrían estar asociadas con el efecto regional de El Niño 1997-1998. La biomasa de zooplancton en la bahía fue relativamente baja durante todo el año, independientemente de las épocas climáticas, lo que se atribuyó a su baja energía hidrográfica interna, su escasa vegetación acuática y a su aislamiento de la influencia marina.

Resumen en inglés

The bay of Chetumal, in the Western Caribbean, is regarded as an uniformly hypohaline and oligotrophic system. In order to define if the zooplankton biomass shows a homogeneous behavior in this coastal system we analyzed the spatio-temporal variation of this parameter (wet weight: mg m-³) during two years (1996, 1997). During 1996, the average annual biomass (11.56 mg m-³) was significantly lower than that recorded during 1997 (16.18 mg m-³). Slightly lower biomass values were observed in northerlies during both years, followed by dry and wet periods, thus suggesting seasonality in the dynamics of this factor in the zooplankton community. Monthly variations were also considerable and suggest that important changes could also be occurring at scales smaller than the seasonal or interannual. Between 45 and 51% of the biomass in 1996 and 1997 was distributed at the outermost and more saline stations of the bay regardless of the season. The high primary production usually related to the inner zone of the bay was not reflected in the zooplankton biomass; this was explained by local distributional restrictions of the resident herbivorous zooplankton and possibly to hypoxia related to local eutrophication. The interannual differences, with higher biomass, temperature, and salinity found in 1997 and also the weak seasonality of that year could be related to the regional effect of El Niño 1997-98. The zooplankton biomass in the bay was relatively low year-round regardless of the season; this was attributed to its low internal hydrographic energy, scarce aquatic vegetation, and to its isolation from the marine influence.

Resumen en español

Se analiza la composición, abundancia y distribución de los eufáusidos del Mar Caribe mexicano durante Agosto de 1986. Las muestras de zooplancton fueron recolecta das durante el crucero ARCOMM I, a bordo del B/O “Justo Sierra” de la UNAM. Los muestreos se realizaron mediante arrastres oblicuos con una red Bongo (malla de 0.5 mm) desde los 200 m hasta la superficie en 28 estaciones. La especie más abundante fue Stylocheiron carinatum , con el 49% del total de eufáusidos recolectados, le siguieron Euphausia americana 9.8% y E. tenera con 7.8%. Las máximas densidades de las tres especies más abundantes se encontraron durante los muestreos nocturnos; esto puede estar relacionado con los patrones migracionales de las especies. El índice de Bray-Curtis originó tres grupos, separados por las variaciones nictemerales de la comunidad de eufáusidos. Las especies se distribuyeron con mayor frecuencia en el área oceánica y estuvieron ausentes en la región nerítica. La fauna local presenta afinidad con la comunidad de eufáusidos del Golfo de México y otras áreas del Mar Caribe. Se encontraron cuatro especies que representan registros nuevos para el Mar Caribe occidental

Resumen en inglés

The composition, abundance and distribution of euphausiids from the southern part of the Mexican Caribbean Sea (August 1986) were sampled during the ARCOMM I cruise on board the R/V “Justo Sierra” of UNAM. Sampling was done using a Bongo-net (0.5 mm mesh size) performing oblique hauls from 200 m to the surface at 28 stations. Of the total euphausiid numbers, the most abundant species was Stylocheiron carinatum (49%), followed by Euphausia americana (9.8%) and E. tenera with (7.8%). The highest total density and that of the three most abundant species occurred during the night sampling, and probably was related to vertical migration patterns. The Bray-Curtis index revealed three station assemblages, related to the day-night variations of the euphausiid community. Species were distributed mainly in the oceanic area, and were absent in the neritic zones. The local fauna shows a strong affinity for the euphausiid community of the Gulf of Mexico and other areas of the Caribbean Sea. Four species are considered to be new records for the western Caribbean Sea.

Resumen en inglés

Seventeen euphausiid species were identified from 97 zooplankton samples collected in the southern part of the Gulf of Mexico during July 1988. About 75% of adult individuals belonged to three species: Stylocheiron carinatum (28.3%), S. suhmi (25.5%) and Euphausia tenera (20.1%). Seaward of the continental shelf, between 61 and 443 adults 1000 m−3 of water filtered were collected in the upper 200 m at night, compared with generally less than 20-94 adults 1000m−3 during daytime. Calyptopis larvae occurred in 78 tows, at mean density of 1346 1000 m−3. Cluster analysis using Bray-Curtis ordination indicated there were day-night and neritic-oceanic differences in the euphausiid community. A separate ordination of deepwater night collections indicated there was no difference between the euphausiid numerical abundance at stations in the Bay of Campeche (area of divergence), compared with those made offshore within Lazy Eddy, a warm-core eddy (area of convergence) which had been shed from the Loop Current the previous Fall 1987. However, although euphausiid species richness was similar in both areas, the two most common species of Stylocheiron dominated the numerical abundance in Lazy Eddy, whereas species of Euphausia were co-dominant with those of Stylocheiron in the Bay of Campeche. These two genera were also co-dominant in the leading edge of a second warm-core eddy (Murphy) that had separated from the Loop Current in April 1988.

Resumen en español

Se caracterizaron y analizaron etnobiológica y económicamente los solares del ejido Francisco I. Madero, municipio de Jitotol, Chiapas. Estos se seleccionaron a partir de una estratificación económica. La caracterización se llevó a cabo con base en métodos etnobiológicos, ecológicos y botánicos, entrevistas semiestructuradas y observaciones participativas. Los resultados reflejan que los solares de Francisco I. Madero son menos complejos en cuanto a estructura y composición de especies que en otras regiones tropicales. Se registraron 138 especies (arbóreas, arbustivas y herbáceas) de las cuales el 89.1% tiene más de un uso, siendo las medicinales, comestibles y ornamentales las de mayor frecuencia. El análisis de varianza muestra que no existen diferencias significativas entre la diversidad, riqueza de especies y los tres niveles económicos. No existe diferencia entre las formas de utilización de los recursos vegetales; pero sí, en el proceso de conocimiento tradicional sobre el manejo de las mismas.

Resumen en inglés

Francisco I. Madero, home gardens were characterized and analyzed ethnobiologically and economically. An economic stratification was realized to select and analized them. The characterization was carried out through ethnobiologic, ecologic and botanic methods, through semi-structured interviews and participatory observations. The results showed that the home gardens in Francisco I. Madero are less complex in regards to their structure and composition than the home gardens in other regions. There are 138 species (arboreal, bush, herbaceous) of which 89.1% have in the majority of the cases more than one use, and frequently they are for medicinal, edible and ornamental purposes. The analysis of variance shows that there are not significant differences between the diversity, the richness of species and the three economic levels. There is not difference between the ways of utilizing plants, however there is a difference between the process of traditional knowledge about their use. Even though the home gardens in Francisco I. Madero are not so diverse, they are a production alternative that could strengthens the family economy since they provide products for subsistence, and the possibility of generating surplus.

Resumen en inglés

The abundance and distribution of 21 species of euphausids collected in surface waters (0-200 m) at 69 stations of the Gulf of Mexico and the Yucatan Shelf was analyzed. Zooplankton samples were taken during the JS8601 cruise on board the R/V "Justo Sierra" of the UNAM, in April-May, 1986. During this survey mesoscale hydrographie features such as anticyclonic and cyclonic gyres, and upwelling, were detected in the area. The most abundant species was Stylocheiron carinatum (29.86%), followed by Euphausia tenera (19.97%) and S. suhmi (15.18%). Species richness increased at night: densities were 3.07 times higher then. Apparently, the migratory behaviour, of euphausids buffered the expected effect of the mesoscale features in the local euphausid community. The Bray-Curtis Index revealed three clusters of stations. The first one represented the influence of coastal and shelf waters on the euphausid community. The second group is a mixed oceanic-shelf community, and the third one was related to the Gulf oligotrophic oceanic waters. A fourth group included shallow areas in which no euphausids occurred. The relatively poor anticyclonic eddies did not influence the local euphausid community although low euphausid densities were expected. The relatively richer features, the cyclones, showed higher average densities. Euphausid densities related to the influence of upwelling areas showed density values similar to those recorded in the anticyclones. Two species (S. suhmi and S. carinatum) occurred in all the Gulf of Mexico regardless of the mesoscale environments or the time of day.

Resumen en alemán

L'abondance et la repartition de 21 especes d'Euphausiaces recoltes dans les eaux de surface (0-200 m) sur 69 stations du Golfe du Mexique et du plateau du Yucatan ont ete analysees. Les echantillons de zooplancton ont ete preleves au cours de la campagne JS8601 a bord du R/V "Justo Sierra" de l'UNAM, en avril-mai 1986. Au cours de cette mission, de variations hydrographiques d'amplitude moyenne comme les phenomenes cycloniques et anticycloniques, ainsi que l'upwelling, ont ete detectees dans la region. Les especes les plus abondantes etaient Stylocheiron carinatum (29,86%) suivie de Euphausia tenera (19,97%) et S. suhmi (15,18%). La richesse specifique augmentait dans les echantillons nocturnes; les densites etaient 3,07 fois plus elevees la nuit. Apparemment le comportement migratoire des Euphausiaces compensait l'effet attendu des particularites hydrographiques dans la communaute locale d'Euphausiaces. L'indice de Bray-Curtis a revele trois groupes de stations.

Le premier representait l'influence des eaux cotieres et de la plate-forme continentale sur la communaute des Euphausiaces. Le second groupe etait une communaute mixte oceanique-plate-forme et le troisieme se rapportait aux eaux oceaniques oligotrophes du Golfe. Un quatrieme groupe incluait les zones peu profondes sans Euphausiaces. Les phenomenes anticycloniques relativement faibles n'avaient pas d'influence sur la communaute locale des Euphausiaces, bien que l'on se soit attendu a des densites d'Euphausiaces basses. Les phenomenes relativement plus marques, les cyclones, ont montre des densites moyennes plus elevees. Les densites d'Euphausiaces liees a l'influence des zones d'upwelling ont indique des valeurs similaires a celles relevees pour les anticyclones. Deux especes (S. suhmi and S. carinatum) sont presentes dans tout le Golfe du Mexique independamment des environnements consideres et du moment de la journee.
