“…Baker et al (1992a) found that 63% of all mortality for adult borers evaluated on berries with hard endosperms above 30 days after infestation in seven experiments carried out in Mexico was due to this fungus; they also pointed out that mortality rates for females was low once they have established inside the endosperm and that most of the time pathogens are the main cause of death. Natural occurrence of B. bassiana is prevalent in CBB populations where no B. bassiana has ever been applied (Monzón et al, 2008). They pointed out that infection levels of the fungus vary considerably throughout a season and between years, and infection levels up to 44% can be found in unsprayed fields.…”

The overlap of generations of coffee berry borer (CBB), Hypothenemus hampei (Ferrari) under field conditions in countries like Colombia hinders the construction of life tables by the sampling of natural populations. In this paper, a field methodology to carry out regular measurements of CBB cohorts inside coffee berries of different ages until harvest, both in coffee trees and in infested berries placed on the ground, is developed and used to compare the life history parameters of CBB. Populations with berries at six ages in three experimental stations (without CBB control) and in a commercial farm in Colombia (with chemical CBB control regularly carried out) were used. The duration of the pre-oviposition period as well as the mortality and survival rates of founder females and the proportion of founders leaving infested berries were strongly influenced by the consistency of berries, with optimum conditions for CBB reproduction as from 120-150 days after flowering. No differences were found between stations for the number of CBB developmental stages; but they had larger values than the commercial farm. The latter also had more than twice the average rate of founders leaving infested berries recorded in the stations. Survival functions (cumulative probabilities of survival) for the pest differed among treatments and between the plant and ground micro-environments. Age of berries at infestation was positively related to the intrinsic rate of increase of borer population; whilst generation time and doubling time were inversely related. No differences were found between sites for the main demographic parameters of the pest.

Desenvolveu-se uma metodologia de campo para realizar medições regulares de coortes da broca em frutos de café de diferentes idades até a colheita, tanto nas plantas quanto em frutos infestados colocados no solo. O método é usado para comparar parâmetros populacionais da praga em frutos de seis idades, em três estações experimentais (sem controle da praga) e em uma fazenda comercial (com controle químico da praga), na Colômbia. A duração do período de pre-oviposição, assim como as taxas de mortalidade e sobrevivência das fêmeas fundadoras e a proporção de fêmeas fundadoras que abandonaram frutos infestados foram fortemente influenciadas pela consistência dos frutos, com condições ótimas para a reprodução da praga a partir de 120-150 dias depois da floração. Não houve diferenças entre estações para o número de estágios de desenvolvimento da praga, mas os valores nestas foram maiores que na fazenda comercial. Esta última teve uma taxa de frutos abandonados duas vezes maior que a...

“…The natural occurrence of B. bassiana infecting CBB is variable, and has been reported at <1% beetles in Brazil [ 104 ], but higher in other regions, i.e. , 44% in Nicaragua [ 105 ], 60% in India [ 106 ] and reached 71% in a study in Cameroon [ 107 ]. The fungus has been developed as an environmentally safe bioinsecticide that is sprayed against CBB but is not toxic to workers and has low impact on non-target organisms including CBB natural enemies.…”

The coffee berry borer (CBB), Hypothenemus hampei Ferrari (Coleoptera: Curculionidae: Scolytinae) is the primary arthropod pest of coffee plantations worldwide. Since its detection in Hawaii (September 2010), coffee growers are facing financial losses due to reduced quality of coffee yields. Several control strategies that include cultural practices, biological control agents (parasitoids), chemical and microbial insecticides (entomopathogenic fungi), and a range of post-harvest sanitation practices have been conducted to manage CBB around the world. In addition, sampling methods including the use of alcohol based traps for monitoring CBB populations have been implemented in some coffee producing countries in Latin America. It is currently unclear which combination of CBB control strategies is optimal under economical, environmental, and sociocultural conditions of Hawaii. This review discusses components of an integrated pest management program for CBB. We focus on practical approaches to provide guidance to coffee farmers in Hawaii. Experiences of integrated pest management (IPM) of CBB learned from Latin America over the past 25 years may be relevant for establishing strategies of control that may fit under Hawaiian coffee farmers’ conditions.

“…A research by Monzón et al (2007) reported the natural occurrence of the insect pathogenic fungus of B. bassiana in Hypothenemus hampei populations throughout the rainy season of 2004 (July-November) and 2005 (July-December). B. bassiana infections were found during most sampling dates in both years, on all three unsprayed coffee farms, the B. bassiana infection levels were higher in 2005 than in 2004 with mean prevalence of 12.1% and 2.7%, respectively.…”

Coffee berry borer (CBB), Hypothenemus hampei Ferr. (Coleoptera, Scolytidae) is generally controlled by applying integrated pest management, particularly through sanitation and using biological agents. Beauveria bassiana is wellknown as an entomopathogenic fungus, which has been proven to be the most effective and prospective agent that could be developed to control CBB. Dissemination of microbial biocontrol agents via insect or predators may has advantages for safe spore dispersal to targeted pests with the added benefit of predation. The research with aim to determine if spores of B. bassiana can be picked up by CBB from disseminated containers had been conducted at Plant Protection Laboratory and Kaliwining Experimental Station of Indonesian Coffee and Cocoa Research Institute. Ten infected coffee berries and ten CBB adults were sprayed with various concentration of B. bassiana suspension, and then infested them in 10 healthy berries in petridish. The same trials was conducted in the field, by infested them to healthy berries on coffee branches. Observation was done on the percentage of infected berries and number of CBB infected by B. bassiana inside the berries. The results showed that spores of B. bassiana could be picked up by CBB from disseminated containers, although it was very low (2.5%). B. bassiana was not effective in suppressing CBB infestation by auto-dissemination, therefore to improve the effectiveness of B. bassiana in controlling CBB, it was advised to re-spray at least 3 times in every cropping season, especially at the flying time of CBB around 2 P.M.
