A coffee agroecosystem model: III. Parasitoids of the coffee berry borer ( Hypothenemus hampei ) [PDF]

open access: yesEcological Modelling, 2017
Abstract Parasitoids native to tropical Africa have been released in the Americas for the biological control of the coffee berry borer (CBB), but their establishment has been checkered. A tritrophic distributed maturation time model for the coffee plant – CBB – three parasitoids ( Phymastichus coffea , Cephalonomia stephanoderis , Prorops nasuta ...

Inbreeding in the coffee berry borer, Hypothenemus hampei (Coleoptera : Scolytidae) estimated from endosulfan resistance phenotype frequencies [PDF]

open access: yes, 1996
An estimate of the inbreeding coefficient, Fis, of the coffee berry borer, #Hypothenemus hampei$ Ferrari, was calculated from genotype frequencies of endosulfan resistance in beetles collected from berries in 41 fields on the East Coast of New Caledonia.

Cloning and expression of an endo-1,4-β-xylanase from the coffee berry borer, Hypothenemus hampei

open access: yesBMC Research Notes, 2012
Background The coffee berry borer, Hypothenemus hampei, reproduces and feeds exclusively on the mature endosperm of the coffee seed, which has a cell wall composed mainly of a heterogeneous mixture of hemicellulose polysaccharides, including ...

α-Amylase inhibitor-1 gene from Phaseolus vulgaris expressed in Coffea arabica plants inhibits α-amylases from the coffee berry borer pest

open access: yesBMC Biotechnology, 2010
Background Coffee is an important crop and is crucial to the economy of many developing countries, generating around US$70 billion per year. There are 115 species in the Coffea genus, but only two, C. arabica and C. canephora, are commercially cultivated.

Selection of entomopathogenic nematodes and evaluation of their compatibility with cyantraniliprole for the control of Hypothenemus hampei

open access: yesSemina: Ciências Agrárias, 2018
Attack by the coffee berry borer Hypothenemus hampei causes significant damage to coffee crops because it affects the quality of the coffee fruit during different developmental stages, which results in production losses. Control of the borer is difficult

Effect of different antimicrobials on the artificial diet for coffee berry borer rearing

open access: yesTemas Agrarios, 2014
The use of antimicrobial agents in artificial diets for the mass rearing of insects is commonly employed to prevent the proliferation of environmental microorganisms, preventing contamination of food and space of the rear insects.
