Characterisation of Bombyx mori odorant-binding proteins reveals that a general odorant-binding protein discriminates between sex pheromone components [PDF]

, 2009
In many insect species, odorant-binding proteins (OBPs) are thought to be responsible for the transport of pheromones and other semiochemicals across the sensillum lymph to the olfactory receptors (ORs) within the antennal sensilla.

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies

Wildlife Biology, EarlyView.
Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

The oxygen and pressure physiology of upper elevational range limits in insects

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate warming is widely expected to cause montane insects to shift upslope, and there is good evidence that some populations are doing so. Nevertheless, patterns are mixed—with evidence supporting upslope, downslope or even no movement of both lower and upper range ...

Ocular Albinism Type 1 Regulates Deltamethrin Tolerance in Lymantria dispar and Drosophila melanogaster

Frontiers in Physiology, 2019
The ocular albinism type 1 (OA1), a pigment cell-specific integral membrane glycoprotein, is a member of the G-protein-coupled receptor (GPCR) superfamily that binds to heterotrimeric G proteins in mammalian cells.

Responses of generalist invertebrate predators to pupal densities of autumnal and winter moths under field conditions [PDF]

, 2013
1. Generalist natural enemies are usually not considered as being capable of causing population cycles in forest insects, but they may influence the population dynamics of their prey in the low density cycle phase when specialist enemies are largely ...

Factors affecting the propensity of tsetse flies to enter houses and attack humans inside : increased risk of sleeping sickness in warmer climates [PDF]

, 2013
Background: Sleeping sickness, or human African trypanosomiasis, is caused by two species of Trypanosoma brucei that are transmitted to humans by tsetse flies (Glossina spp.) when these insects take a bloodmeal.

How do insects pollinate flowers? Behaviour during visitation determines high pollination efficiency by a generalist insect

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem services provide essential benefits to human survival and well‐being. Animal behaviour is central to the delivery of many ecosystem services, yet we know little about how behaviour drives services' provision.

Larvae of Megaselia Róndani, 1856 (Diptera: Phoridae) as parasitoid of Sphingidae (Lepidoptera) and its frugivory on avocado

Entomological Communications, 2020
The members of the family Phoridae (Insecta: Diptera), whose adults are commonly known as scuttle fly or humpbacked fly, differ widely as to their feeding habits in the larval and adult stages.

Large parameter uncertainty persists in soil food web models integrating stoichiometry, respiration and assimilation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil food web models are essential for linking animal diversity to carbon and nutrient cycling. However, it is unclear how soil animals regulate excess carbon when nutrient availability limits their growth and how to best represent animal respiration in these models. To
