Evaluation of the Distribution and Impacts of Parasites, Pathogens, and Pesticides on Honey Bee (Apis mellifera) Populations in East Africa
TLDR
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.
New mosquito larvicidal tetranortriterpenoids from Turraea wakefieldii and Turraea floribunda.
TLDR
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.
Aggregation pheromone system of adult gregarious desert locust schistocerca gregaria (forskal)
TLDR
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.
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…
Odorants that Induce Hygienic Behavior in Honeybees: Identification of Volatile Compounds in Chalkbrood-Infected Honeybee Larvae
TLDR
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.
Multitrophic interaction facilitates parasite–host relationship between an invasive beetle and the honey bee
TLDR
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
TLDR
The results show that the edible stink bug is a nutrient- and antioxidant-rich source of food and health benefits for human consumption and use of better handling and storage methods can help eliminate contamination of the Edible stink bug with the carcinogen aflatoxin and ensure its safety as human food.
Response of the small hive beetle (Aethina tumida) to honey bee (Apis mellifera) and beehive-produced volatiles
TLDR
Females were more responsive than males to the different volatile sources, with greater response in tests with unripe honey, and Super Q-trapped volatiles from worker bees elicited a response comparable to the response to living workers, while trapped volatile from other sources were not attractive.
Identification of Behaviourally Active Components from Maize Volatiles for the Stemborer Parasitoid Cotesia Flavipes Cameron (Hymenoptera: Braconidae)
In the present study, Y-tube olfactometric assays confirmed that volatiles from maize seedlings infested with Chilo partellus larvae were more attractive to the borer’s larval endoparasitoid Cotesia…
