Mosquito Management is Key in Creating Popular Urban Wetlands

A study that shows mosquitoes might benefit from wetland-management tactics aimed at protecting frogs illustrates the complicated ecological dynamics present in urban wetlands. Understanding the habitat requirements and ecological interactions of local mosquito species is critical to balancing such wetlands' risks and benefits.

Mesh to Reduce Bycatch: A Simple Solution to a Sticky Problem

Sticky traps used to monitor orchards for the Asian citrus psyllid often catch an array of larger non-target organisms. But a thin layer of mesh fabric—the same kind used in bridal veils and ballet tutus—makes an effective screen to eliminate most bycatch while still catching the target pests.

Aedes aegypti mosquito

Trap Modifications Collect Mosquito Waste for Virus Detection

Public health officials could soon be able to detect viruses in mosquitoes in the wild much more quickly and easily—thanks to the insect equivalent of a urine test. A new study in Australia shows that two kinds of commonly used mosquito traps can be readily modified to collect mosquito excreta, or liquid waste droplets, to be tested for signs of viruses.

Assay Array: Entomologists’ Lab Tests Expose Insect Secrets

Entomologists can find out a lot about an insect through some simple chemical reactions in a lab. A new review offers a guide to the wide variety of tests, or assays, that can be conducted to measure the fats, sugars, and other compounds in an insect's body—thereby revealing useful clues about how it stores and uses energy.

Bombus rupestris

For Insect Ecologists, Some Rare Species Interactions Are a Sign of Things to Come

In an era of human-driven ecological change, crucial interactions between and among insect species and plants can disappear before their participating species do. A new special collection in Annals of the Entomological Society of America looks at how insect ecologists are studying these rare interactions and what they mean for our efforts to conserve even the rarest links in the rich web of interactions all around us. 

Toxorhynchites rutilus mosquito larva feeding

Meet the Mosquito With a Big Appetite—for Other Mosquitoes

The mosquito species Toxorhynchites rutilus is harmless to humans but is a voracious predator of other mosquitoes. Researchers in Houston, Texas, are hoping the "mosquito assassin" could be put into action as a tool for controlling mosquitoes that carry human pathogens—if they can find an efficient way to raise the predator mosquitoes in the lab.

Trichopria anastrephae

New Study Aims to Protect Parasitoids of Spotted-Wing Drosophila

Use of an insecticide can be counterproductive if it also harms natural enemies of a target pest. A new study puts several insecticides currently in use to manage spotted-wing drosophila to the test to see how they do or don't affect parasitoids of the invasive fruit fly.

To Boost IPM Adoption, Treat It as a Complex Social System

Pest management is more than just matching pests with control methods. A tangled web of societal influences also play a role in growers' decisions and their uptake of integrated pest management, and researchers say the science of "social ecological systems" can inform efforts to increase IPM adoption.
