Abiotic mortality factors of the coffee berry borer (Hypothenemus hampei) - 1994
Ilus. 5 tab. 12 ref. Sum. (En)
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 m ortality 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.
