Endangered Maritime Ringlet Shows Continued Decline in Eastern Canada

Coenonympha nipisiquit

An endangered butterfly species in eastern Canada appears to be declining in numbers, but a better understanding of how environmental conditions affect its lifecycle may better inform conservation efforts, according to a new study in Environmental Entomology. Coenonympha nipisiquit, also known as the maritime ringlet, lives in just 10 salt marshes in Quebec and New […]

Stink Bug Traps in Gardens may Increase Damage to Tomatoes

The invasive brown marmorated stink bug (Halyomorpha halys) is an important pest of fruits and vegetables. To counter them, some home gardeners use pheromone-baited traps that are designed to attract, trap, and kill them. However, new research from entomologists at the University of Maryland suggests that the traps may actually increase stink bug damage to […]

If You’re Trying to Find Insects in the Forest, Look Up

Earlier this week, the Lyman Entomological Museum blog posted a piece about an article that appears in the journal Environmental Entomology. It describes how researchers from McGill University explored the changes in beetle and fly diversity as they went from ground level up to the canopy in maple forests in southern Quebec. Although the different […]

Beneficial Insects and Nematodes are not Harmed by Genetically-modified, Insect-resistant Plants

A large body of literature has shown that genetically-modified plants that produce proteins from the bacterium Bacillus thuringiensis (Bt) to protect themselves from insect pests have little to no effect on a wide range of nontarget insects. However, concerns about Bt crops still exist. Now two new studies using more exacting methods show that Bt […]

First African Study on Biodiversity in Genetically Modified Maize Finds Insects Abundant

Previous studies from China, Spain, and the United States on genetically modified (GM) rice, cotton, and maize have concluded that the biodiversity of insects and related arthropods in GM crop fields was essentially the same as that among conventional crops. Now a new study from South Africa shows similar results. The study is described in […]
