Resumen en inglés

Life history studies were conducted in the laboratory on the African parasitoid Prorops nasuta Waterston (Hymenoptera: Bethylidae), a parasitoid of the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae). The female wasp enters an infested coffee berry, kills the adult borer and seals the entrance of the berry with the body of the borer, impeding the entry of other organisms into the berry. The preoviposition period ranges from 3 to 14 days (mean 5.42 ± 0.37 SE). During this time females feed on the immature stages and paralyse fully grown larvae and pupae of the CBB. P. nasuta is an idiobiont solitary ectoparasitoid. Eggs are laid externally on the last instar larvae and pupae. Mean development time (egg to adult) for males and females was 27.7 (±0.37 SE) and 30 (±0.12 SE) days, respectively. Median survival for wasps fed on final instar CBB larvae was 27.7 days, significantly longer than any other treatment, while for females without food it was 2.5 days. In culture, females produced an average of 4.3 (±0.39 SE) progeny during their lifetimes. Adults began emerging at 30.6 days (±0.28 SE) after cultures were started and peak production was reached at 36 days, declining thereafter. Males normally emerged from coffee beans 2–3 days before females. Males usually emerged from 07:00 to 09:00h and females from 10:00 to 14:00 h. The culture sex ratio (proportion of males) was 0.21. Virgin females produced only male offspring.

Resumen en inglés

Mortality of the coffee berry borer was studied under controlled laboratory conditions in Tapachula, Mexico. For adult female borers subjected to a range of relative humidities (RH) without food at 25°C, the longest mean survival time (20 days) was obtained at 93.5% RH. Adult borer survival was also studied at a range of temperatures for a fixed relative humidity (93.5% RH); at 20°C mean survival time was 28 days. Fecundity and mortality of borer stages in berries was studied for a range of humidities at 25°C. Maximum fecundity was obtained at 90 and 93.5% RH. Immature stages were ejected from the berry at 84% RH and above, which is interpreted as a form of brood hygiene.

Resumen en inglés

Emergence of coffee berry borer, Hypothenemus hampei (Ferrari), from infested coffee berries (Coffea arabica) was studied in the laboratory under controlled temperature and relative humidity (RH) regimes. Low humidities (<60% RH, 25°C) provoked rapid evacuation of adults. Emergence was at a minimum at 90% RH. A steady increase in emergence occurred at values from 90 to 100% RH. Emergence was low below 20°C (90 and 100% RH) and increased markedly between 20 and 25°C. There was no significant increase in emergence above 25°C. Using a simple flight event recorder, emergence flight times were found to peak at the time of maximum daily ambient temperatures on successive days. Under constant temperature conditions successive peaks of emergence were not seen. Results are discussed in relation to control and sampling procedures.

Resumen en inglés

1. A series of experiments involving artificial infestation of coffee trees with coffee berry borer were carried out in Chiapas, Mexico. Attacked berries were marked to identify time of infestation. 2. Berry samples were taken every 3-4 days for periods of up to 91 days and number of developmental stages present recorded. Two peaks of egg production occurred at about 10 and 50 days post-infestation. The second peak is probably the work of one or more daughters of the founding female. 3. Berries removed and placed on the ground 4 days after infestation, developed significantly (P < 0.0001) larger numbers of eggs than berries remaining on the tree

4. Mortality of the founding female was low once established in the endosperm. Very few dead immature stages were found though calculations based on egg- laying schedules suggest that mortality may be 30% after 30 days of development. Apparent mortality of adult progeny rarely exceeded 10%. The main causes of mortality were pathogens that either attacked the endosperm causing the female to abandon the berry in many cases, or attacked the insect directly. 5. Innate capacity for increase (r) was estimated as 0-065 per day; cohort generation time was 45 days, doubling time, 11 days.

Resumen en español

Se probaron varios tipos de trampas en un ambiente húmedo en el Estado de Chiapas, México (región del Soconusco) con el fin de desarrollar un mecanismo más efectivo de monitoreo de poblaciones de Mosca del Mediterraneo, Ceratitis capitata (Wiedemann). Todas las trampas fueron cebadas con trimedlure y todas las moscas capturadas fueron moscas estériles liberadas ex profeso para el estudio. La trampa IP Delta capturo más moscas que la trampa Jackson que se utiliza actualmente en México. Las diferencias entre las trampas muestran evidencia de una dependencia de la densidad. Se encontraron diferencias significativas en la temperatura interna de los dos tipos de trampas cuando estas estuvieron expuestas a los rayos del sol y en la capacidad de las trampas de protejer la superficie pegajosa bajo condiciones de lluvia intensa. Se discuten los resultados en relación a los requerimientos de los programas de trampeo de Mosca Med en México.

Resumen en inglés

Synthetic components of the male sex pheromone of Ceratitis capitata were tested in traps located in coffee and mango trees in Chiapas, Mexico. Traps with linalool, 2,3-dimethylpyrazine, 2,5-dimethylpyrazine or geranyl acetate were all significantly more attractive to released sterile flies than unbaited traps. Sex ratios of catches varied greatly; most females were caught during periods of peak ripe fruit production in coffee and mango. Delta traps caught more flies than Jackson traps. No component or mixture caught more flies than trimedlure. Ammonia with ethyl pyrazine caught significantly more flies than either component separately.
