In June 2013, a pesticide application on ornamental trees in a shopping-center parking lot in Wilsonville, Oregon, led to the largest documented mass fatality of bumble bees in North America. A new analysis of the incident estimates more than 100,000 bees from nearly 600 colonies were killed, which researchers cite as a cautionary tale about the dangers of pesticides to native bee populations.
Releasing millions of sterile insects to interfere with a wild pest population won't work if irradiating the insects also hinders their flight capacity. A new study shows this may be the case with navel orangeworm moths (Amyelois transitella), and further fine-tuning will be necessary to build a successful sterile insect technique operation to manage the pest.
Larvae of the darkling beetle species Zophobas morio have earned the nickname "superworms" for their larger size and increased nutritional potential as food and feed compared to yellow mealworms. And yet less research and regulatory consideration has focused on Z. morio, something a pair of researchers in Greece hope to change.
Monitoring for cockroach infestations in homes and buildings is hindered by a lack of effective and practical attractants, but researchers at Rutgers University say a mix of extracts from apple and blueberry has proven highly effective in lab and field settings and could lead to more successful cockroach integrated pest management programs.
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.
