Occurrence of Hymenoptera on pig carcasses in a tropical rainforest in Central Amazonia, Brazil

open access: yesSociobiology, 2019
Hymenotpera species may act as necrophagous, consuming decomposing tissues, as predators, when they feed on other immature and adult insects, and parasites of larvae and pupae of dipterans and coleopterans that colonize the carcasses.

Substrate Preference of Black Soldier Fly Larvae Is Influenced by Rearing History

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
BSF larvae were reared under six different conditions: low, medium, or high larval density and on low, medium, and high‐water feeds to investigate feed choice behaviour. Larvae reared under all six conditions preferred substrate colonised by conspecifics. Low‐water feed caused slower larval growth and development.

Task partitioning in insect societies. I. Effect of colony size on queueing delay and colony ergonomic efficiency [PDF]

open access: yes, 1999
The collection and handling of colony resources such as food, water, and nest construction material is often divided into subtasks in which the material is passed from one worker to another. This is known as task partitioning.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

To provide pollinator nesting habitat, cut dead perennial stems in their first winter

open access: yesInsect Conservation and Diversity, EarlyView.
Garden management practises need to consider stem‐nesting bees and wasps to avoid destroying active nests and important nesting materials. Volunteers collected samples of dead stems (in situ where they grew) in winter, spring, summer and fall as part of a participatory research project.
