Semiochemicals used in Host Location by the Coffee berry Borer, Hypothenemus hampei

Journal of Chemical Ecology, 2009
The coffee berry borer, Hypothenemus hampei is a serious pest in many coffee growing countries. Electrophysiological and behavioral responses of H. hampei to volatiles of different phenological stages of coffee, Coffea arabica, fruits were studied in order to identify volatile semiochemicals used in host location.

Still little evidence of poleward range shifts in the tropics, but lowland biotic attrition may be underway

Biotropica, Volume 57, Issue 1, January 2025.
Based on reviews of more than 450 studies, documented climate‐driven species range shifts within the terrestrial tropics have been exclusively upslope—none poleward, a pattern we attribute to the lack of latitudinal temperature gradients within the tropics, as illustrated here.

Climate Change Impacts on Agriculture: A Review of Plant Diseases and Insect Pests in Ethiopia and East Africa, With Adaptation and Mitigation Strategies

Advances in Agriculture, Volume 2025, Issue 1, 2025.
Climate change significantly threatens global agriculture, with East Africa, particularly Ethiopia, being highly vulnerable due to its reliance on rain‐fed farming. This review investigates the effects of climate change on plant diseases and insect pests, underscoring the urgent need for adaptation and mitigation measures. Ethiopia’s observable climate

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

, 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.

What can an analysis of Australian tropical rainforest bark beetles suggest about the missing millions of Earth's insect species?

Insect Conservation and Diversity, Volume 17, Issue 6, Page 1156-1166, November 2024.
In an analysis of 10,097 Australian tropical rainforest bark beetles (Scolytinae) from eight different ecological studies, we found that 58 of the 107 species identified are undescribed. As hypothesised, new species are significantly smaller, less abundant and less widespread than described species making them more extinction‐prone than named species ...
