The drivers that affect survival rates of butterfly and moth pupae are understudied compared to their larval and adult stages. A new study examines silverspotted skippers (Epargyreus clarus) in their most vulnerable stage—and why their overwintering generations survive pupation at much higher rates than summer generations.
A look at the body of research on how and when day lengths trigger mosquitoes to enter winter diapause suggests more data on mosquito species' critical photoperiods and their relation to latitude and altitude could better align surveillance and management efforts with mosquitoes' seasonally active periods.
New Zealand is working hard to keep the invasive brown marmorated stink bug from reaching its shores, and researchers there are working with colleagues at the U.S. Department of Agriculture to understand the dynamics of the pest's ocean voyage aboard cargo ships bound for the island nation, in hopes of finding new ways to detect and prevent its arrival.
The khapra beetle does outsize damage to stored grains and is a top target at ports and border crossings. Researchers in Canada have found the threshold temperature that will kill the beetle at all life stages, even diapause.
