The results suggest that Varroa, the three viruses, and Nosema have been relatively recently introduced into Kenya, but these factors do not yet appear to be impacting Kenyan bee populations, and chemical control for VarroA and NoseMA are not necessary for Kenyan bees at this time.
African edible insects for food and feed: inventory, diversity, commonalities and contribution to food security
This paper reviews entomophagy as practised in Africa within the context of food and nutritional security by providing an inventory of the various species of insects that are consumed on the…

Comparison of the aggregation responses of young and older adults to the crude, older-adult, volatile extract and different synthetic blends of the six compounds showed that the aggregation pheromone system of the adult gregarious locust consists of phenylacetonitrile, guaiacol, phenol, and benzaldehyde.

Three volatile compounds, collected from larvae infected with the fungal pathogen Ascosphaera apis and detected by adult honey bees, were identified by coupled gas chromatography-electroantennographic detection and gas Chromatography-mass spectrometry and two field bioassays revealed that one of the compounds, phenethyl acetate, is a key compound associated with Ascosphara apis-infected larvae that induces hygienic behavior.

It is reported that in the parasitic relationship between the European honey bee and the small hive beetle, Aethina tumida, the honey bee's alarm pheromones serve a negative function because they are potent attractants for the beetle.
A scientific note on Varroa destructor found in East Africa; threat or opportunity?
In many areas of the world where it is managed, the honeybee, Apis mellifera, has been plagued by diseases, pests and parasites. Of these, the parasitic mite, Varroa destructor Anderson and Truman…
Aflatoxin Contamination Detected in Nutrient and Anti-Oxidant Rich Edible Stink Bug Stored in Recycled Grain Containers

Four new limonoids comprising a vilasininoid 1 and three havanensinoids 2-4 were isolated from the chloroform fractions of the methanol extracts of Turraea wakefieldii and T. floribunda to show mosquito larvicidal activity against third-instar larvae of Anopheles gambiae sensu stricto.
