Antennal chemoreceptors in the European ectoparasitoid Sclerodermus cereicollis (Hymenoptera: Bethylidae)

open access: yesMicroscopy Research and Technique, Volume 87, Issue 10, Page 2275-2291, October 2024.
An evident sexual dimorphism concerning antennae length, types, number, and distribution of chemosensilla is shown. Long sensilla basiconica are present in females and could play a role in the host location and/or maternal care. Multiporous sensilla chaetica, longer and mostly represented in males, could play a role in intraspecific relationships ...

Digestion of the inhibitor AI by Hypothenemus hampei aspartic proteinases

open access: yesRevista Colombiana de Entomología, 2005
The digestive fluid of the coffee berry borer, Hypothenemus hampei, larvae contains aspartic proteases, which show greatest activity at pH 3,0 and a temperature of 40°C. By using isoelectric focusing gels, it was possible to observe two well-defined bands in the intestinal tract.

Pest categorisation of non‐EU Scolytinae on non‐coniferous hosts

open access: yesEFSA Journal, Volume 22, Issue 9, September 2024.
Abstract The EFSA Panel on Plant Health performed a group pest categorisation for the EU territory of non‐EU Scolytinae (Coleoptera: Curculionidae) on non‐coniferous hosts, which total 6495 known species. Most species attack apparently healthy, weakened or dead trees, either feeding on the phloem (‘bark beetles’ subgroup) or on fungi inoculated into ...

A Beetle in a Haystack: Are There Alternate Hosts of the Coffee Berry Borer (Hypothenemus hampei) in Puerto Rico?

open access: yesAgronomy, 2020
Can the coffee berry borer (Hypothenemus hampei, or CBB) use host plants other than coffee for food and shelter? The use of fruits other than coffee has been reported.

Insect–microbe interactions and their influence on organisms and ecosystems

open access: yesEcology and Evolution, Volume 14, Issue 7, July 2024.
Insect‐symbiont interactions can have a variety of impacts on organisms and the ecosystem. These multitrophic interactions can result in differential attraction of beneficial insects or natural enemies. Additinoally, these interactions can influence plant and/or soil health as well as microbiome composition.

Coffee berry borer Hypothenemus hampei (Coleoptera: Curculionidae): searching for sustainable control strategies [PDF]

open access: yesBulletin of Entomological Research, 2006
AbstractThe coffee berry borer Hypothenemus hampei (Ferrari) is the most serious pest of the world's most valuable tropical export crop. Since the last review on this insect was published six years ago, many new studies have contributed to an improved insight into the biology and ecology of the beetle, and have indicated new avenues for integrated and ...

Behavioural interactions between co‐habiting females and their impact on productivity and offspring sex ratios in the coffee berry borer, Hypothenemus hampei

open access: yesAgricultural and Forest Entomology, Volume 26, Issue 2, Page 262-272, May 2024.
Abstract The coffee berry borer (CBB) Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) has invaded all coffee‐producing regions of the world and causes substantial economic losses every year. A single female beetle typically infests one coffee berry, which her offspring consume over the course of development.

Sperm storage organs change with female age and mating history in the Golden Silk spider Trichonephila clavipes (Araneae: Araneidae)

open access: yesJournal of Zoology, Volume 323, Issue 1, Page 19-28, May 2024.
Female sperm storage organs in arthropods are used as taxonomic characters because they are assumed not to change after maturation. We show that the size of the spermathecae in the Golden Silk spider, Trichonephila clavipes, increases twofold with mating. The sclerotization of the spermathecal wall increased significantly with age.

Hongos asociados a Hypothenemus hampei (Coleoptera: Curculionidae: Scolytinae) en Tabasco, México

open access: yesRevista Colombiana de Entomología, 2020
En el estado de Tabasco, México, la broca del café Hypothenemus hampei, se registró por primera vez en 2004. Desde entonces se ha convertido en la principal limitante insectil de la producción de café. El objetivo del presente trabajo fue identificar la micobiota asociada a adultos de H.

Biophysical Constraints to Robusta Coffee Productivity in Low, Moderate, and High Rainfall Areas

open access: yesInternational Journal of Agronomy, Volume 2024, Issue 1, 2024.
Globally, coffee (Coffea spp.) is a major commodity in terms of production and trade. Although Uganda is seventh among the major producing countries, yields remain low at 500 kg/ha. Understanding the biophysical constraining factors is vital to inform efforts toward closing the yield gap.
