Contact and fumigant toxicity of five pesticidal plants against Callosobruchus maculatus (Coleoptera: Chrysomelidae) in stored cowpea (Vigna unguiculata).
Insecticidal activities of five pesticidal plant species, , (Syn: ) , , and , which have been reported to control storage pests, were evaluated as leaf powders against (Fabricius 1775) in stored cowpea. Their efficacy was compared with the commercial pesticide Actellic dust (pirimiphos-methyl) at the recommended concentration (50 g/90... -

Secondary metabolites from nectar and pollen: a resource for ecological and evolutionary studies
Floral chemistry mediates plant interactions with herbivores, pathogens, and pollinators. The chemistry of floral nectar and pollen, the primary food rewards for pollinators, can affect both plant reproduction and pollinator health. Although the existence and functional significance of nectar and pollen secondary metabolites has long been known, comprehensive quantitative characterizations...Palmer-Young, Evan ; Farrell, Iain ; Adler, Lynn ; Milano, Nelson ; Egan, Paul …

Age-related pharmacodynamics in a bumblebee–microsporidian system mirror similar patterns in vertebrates
Immune systems provide a key defence against diseases. However, they are not a panacea and so both vertebrates and invertebrates co-opt naturally occurring bioactive compounds to treat themselves against parasites and pathogens. In vertebrates, this co-option is complex, with pharmacodynamics leading to differential effects of treatment at different life stages,...Folly, Arran J. ; Stevenson, Philip C. ; Brown, Mark J. F.

Opportunities and Scope for Botanical Extracts and Products for the Management of Fall Armyworm (Spodoptera frugiperda) for Smallholders in Africa.
Fall Armyworm (FAW) (Spodoptera frugiperda) is a polyphagous and highly destructive pest of many crops. It was recently introduced into Africa and now represents a serious threat to food security, particularly because of yield losses in maize, which is the staple food for the majority of small-scale farmers in Africa....Rioba, Naomi B. ; Stevenson, Philip C.
