A chemical, electrophysiological and behavioral study was carried out to analyze the volatile compounds of the Brindley's gland of Rhodnius prolixus Stål. Six compounds were found in the Brindley's gland of males and females: acetic, isobutyric, caproic acids and three compounds not identified. The mass spectra of the unidentified compounds have the appearance of a propionate ester, a butyrate ester and a valerate ester. There was no difference in the concentration of these compounds in the glands of males and females. The major component was isobutyric acid. The electroantennographic (EAG) evaluation of isobutyric, acetic, and caproic acids elicited weak responses. With both sexes, the EAG responses for the acids were no different from the control response at any of the doses evaluated (1, 10, 100, and 500 microg). The behavioral response of males and females to acetic, isobutyric, and caproic acids at 1, 5, and 10 microg and binary and tertiary mixtures of the three compounds was evaluated in a Y-olfactometer. Males showed preference for acetic acid at a dose of 1 microg, but not at 5 or 10 microg. Females showed preference for this compound at the dose of 5 microg. Males showed preference for isobutyric acid at 1 and 5 microg, but not at 10 microg. Females did not show any preference for isobutyric acid. Males were attracted to caproic acid at the dose of 1 and 10 microg. Females were attracted to the caproic acid. Males, but not females, preferred the mixture of acetic and isobutyric acids over control. Neither males nor females showed preference for the mixture of acetic and caproic acids or hexane control. Females, but not males, were attracted to the mixture of the isobutyric and caproic acids. Only males showed a positive response for the tertiary mixture of the acids.

In this study, we investigated the influence of cultivar type, fruit ripeness, and damage by conspecific larvae on the attraction of Anastrepha obliqua (Macquart) (Diptera: Tephritidae) to and oviposition on carambola fruit (Averroha carambola L.). The attraction of both sexes of A. obliqua to fruit of different quality was evaluated through cage experiments in the field, and the oviposition preferences of mated females were examined in laboratory tests. Both sexes, mated or virgin, were more attracted to the "Maha" fruit than to the "Golden Star" fruit, and the females oviposited more frequently on the Maha cultivar than the Golden Star cultivar. Both sexes were more attracted to ripe and half-ripe Maha fruits than to mature green fruit, and although females did not show a preference for ovipositing on half-ripe or ripe fruits, they did not oviposit on mature green fruits. Males did not show a preference for the volatiles from uninfested, artificially damaged, or infested Maha fruits, but females were more attracted to uninfested fruits than to artificially damaged and infested Maha fruits. Furthermore, females preferred to oviposit on uninfested fruits compared with artificially damaged fruit, and they did not oviposit on infested fruits.

Resumen en español

Muchos investigadores se han dedicado a estudiar los problemas de la miel de Apis mellifera, su fuente vegetal y origen; cómo el apicultor puede manejar sus abejas y obtener el máximo de la cosecha de miel; cómo la miel puede ser mejor extractada del panal y prepararla para el mercado. Sin embargo existe poca información sobre las mieles de los Meliponinos, las que según González (1984) tenían una gran relevancia para el pueblo Maya que la usaban como componente básico en su alimentación, en su farmacopea y en el comercio. En el presente se evaluaron las características químicas y físicas de las mieles de producidas por las abejas Apis mellifera así como de cuatro especies de Melipóninos, Melipona beecheii, Scaptotrigona pachysoma, Plebeia sp. y Tetragonisca jaty localizadas en el Municipio de Unión Juárez, Chiapas, México. Los parámetros evaluados fueron los mismos que se consideran para las mieles de Apis mellifera como porcentaje de humedad, pH, acidez total, porcentaje de los azúcares (fructosa, glucosa y sacarosa), contenido de hidroximetilfurfural (HMF), color y conductividad eléctrica. Las mieles de los Meliponinos resultaron ser más húmedas que las de Apis mellifera, siendo las de Plebeia sp. las más húmedas. La acidez de la miel de Plebeia sp. resultó ser más alta que las otras. En cuanto al contenido de azucares no presentó diferencias. Las mieles de Apis mellifera presentaron mayor contenido de HMF que la de los Meliponinos. Las mieles de los Meliponinos fueron más claras que las de Apis mellifera.

Resumen en inglés

Pesticides are used intensively for crop protection in tropical fruit plantations. Assessments of the relative risks posed by pesticides are needed to assist in the development of management plans that minimize ecological impacts. In this study, the risk indicator SYNOPS_2 was used to compare risks to aquatic ecosystems by pesticides commonly used in papaya plantations. Plant interception and spray drift were measured during six applications of three pesticides (chlorothalonil, chloropyrifos, and malathion) using a turbo fan driven sprayer. Plant interception was estimated to be higher (42.6 ± 12.7%; p = 0.04) in late (8–14 months old) than in early (4 months old) trees (20.1 ± 25.3%). Chlorothalonil concentrations of up to 11.0 μg L− 1 were found in water from an adjacent ditch after field application. Concentrations of this pesticide (7.4 ± 4.1 μg L− 1) in runoff water were also significantly (p < 0.01) higher than those of malathion (2.4 ± 1.9 μg L− 1) and chlorpyrifos (0.8 ± 0.5 μg L− 1). Good correlation between measured and predicted values (r2 = 0.56–0.85, p < 0.01) showed that SYNOPS_2 is able to describe trends in runoff pollution in papaya plantations.

Linear equations were obtained in order to correct numerical disagreement between measured and calculated runoff concentrations. An independent test showed a reasonable agreement between measured chlorothalonil concentrations and the predicted values using the proposed equations. Fifteen pesticides used in papaya cultivation were ranked according to their calculated chronic biological risk index. Pesticides with the highest risk index for non-target organisms were: chlorothalonil for algae, lambda cyahalotrin for Daphnia and fish, and malathion for earthworms. Chlorothalonil was the pesticide with the highest exposure level in water and therefore represents a high risk for aquatic life. Results show that SYNOPS_2 can be used as a pesticide risk indicator on papaya and possibly other tropical fruit plantations.

Resumen en inglés

In the south of Mexico, attempts to control severe infestations of the coffee berry borer Hypothenemus hampei Ferrari (Coleoptera: Scolytidae), by means of two imported African parasitoids, Cephalonomia stephanoderis Betrem and Prorops nasuta Waterston (Hymenoptera: Bethylidae), have been less than satisfactory. The lack of a suitable alternative food source in the field, such as floral nectar, could be one reason for this result. Both parasitoids have been shown to feed upon the nectar of Euphorbia hirta L. (Euphorbiaceae) under laboratory conditions. In these experiments, females of C. stephanoderis and P. nasuta survived up to 55 and 17 days, respectively, when provided daily with a fresh E. hirta flower. Survival time with diluted honey was 41 and 8 days maximum and in the case of the control (no food or water), 7 and 4 days, respectively. Qualitative analysis of the nectar showed the presence of saccharose, fructose and glucose. Parasitoids, isolated in test tubes, were daily given drops of 1M, 2.5M and 5M solutions of the three sugars (5M, saccharose and glucose only) until death. Saccharose, at a concentration of 2.5M, gave the best survival rates for both parasitoids, up to 59 and 28 days for C. stephanoderis and P. nasuta, respectively.
