“…These results are most likely due to the toxic effects of endosulfan sprays in the commercial farm. The above situation, added to an atypical climatic situation during the year of the study were most likely responsible for the abandonment and/or death of borers when they start to perforate the berries, supporting evidence come from Baker et al (1992a) who reported the highest rate of unpenetrated berries (36.5%) in Mexico for infestations done during the wet season. Such high abandonment levels in the commercial farm, where chemicals were employed, attest to the lethal effectiveness of endosulfan and provide additional support that much abandonment of berries is linked to mortality.…”

“…This last treatment (150 DAF) was the only one that could be compared with its equivalent in tree berries and in this case, no differences between the two micro-environments were found as to the number of developmental stages (F 1, 50 = 0.53, p = 0.4713) and alive adults for the founder generation (F 1, 72 = 0.24, p = 0.6275). Mortality in ground berries was much higher than that found in a similar experiment under dry season conditions in Mexico (Baker et al, 1992a). Penados and Ochoa (1977) and Mathieu et al (1997) have demonstrated that females may delay oviposition as a mechanism of adaptation under unfavorable conditions.…”

“…This behavior is consistent with reports from Montoya-Osorio and Cárdenas-Murillo (1994) and Sreedharan et al (1994). Thus it is improbable that under Colombian field conditions egg laying is initiated from as soon as the second day after attack, as in reports of Baker et al (1992a) in Mexico.…”

“…This abandonment could be therefore considered as an additional cause of unexplained mortality. Baker et al (1992a) suggest that abandoned perforated fruits may be an additional indication of borer mortality; they also point out that dead immature stages can disappear quickly from the berries due to cleaning activities of the brood performed by the mother.…”

“…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).…”

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...

Insectivorous birds can provide ecological and economic services by decreasing pest populations in agricultural systems, but the magnitude of effect is often debated. We modeled the capacity for birds to suppress pest population growth using a common tropical coffee pest, the coffee berry borer (CBB) (Hypothenemus hampei) as a study system. Previous field experiments show that birds play a role in suppressing CBB infestations through predation, but the degree to which birds can suppress population growth enough to control infestations is unknown since CBB are only vulnerable to predators when gravid females disperse. Using previously published data on CBB life‐stage survivability, we constructed a female‐only, daily time‐step, deterministic Leslie matrix and projected CBB population growth for a single breeding season. Our goal was to assess the plausibility of CBB suppression by birds as a function of avian energy requirements, reported avian densities on coffee farms, prey composition of avian diets, estimated a caloric value of CBB, and the initial starting population size. Our model showed CBB population growth became exponential (λdaily = 1.042) and that at low, but not medium or high population sizes, were birds able to reduce population growth by 50%. In general, birds exert predation pressure on insect populations, but the ability to control infestations is complex, and is likely dependent on the initial CBB population size.

Coffee berry borer Hypothenemus hampei (Coleoptera: Scolytidae), denoted CBB, is the most important insect pest of coffee worldwide, with a high impact on the economy of coffee producing countries. The insect spends a great part of its life cycle inside the coffee berry and causes severe crop losses. Biological control based on the use of an entomopathogenic fungus is a major alternative to chemical pesticides in order to control CBB. The fungus is sprayed on the coffee berries to kill CBB when the insects drill holes to penetrate inside the berries. Our aim in this work is to optimise the fungus application, using a modelling approach. We first formulate a mathematical model describing the infestation dynamics of coffee berries by CBB. We analyse the model and show that the stability of the pest-free and coexistence equilibria depends on the basic reproduction number. To introduce a control variable corresponding to the application of an entomopathogenic fungus, we then extend the model and include the fungus dynamics. We formulate an optimal problem which consists in maximising the coffee yield, while minimising the control cost, as well as the CBB population for the next cropping season. The existence of the optimal control and the necessary optimality condition are established using Pontryagin's Maximum Principle. The optimal control problem is solved numerically using the BOCOP software and simulations are provided, showing that the use of entomopathogenic fungus effectively controls CBB.
