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.
The list of invasive insects in the United States is a long one, but one entomologist offers his list of the top four "most wanted"—plus a note about how entomologists are working to better manage the challenge of invasive insect species.
The invasive spotted lanternfly often lays its eggs on tree limbs and trunks. A new study finds that putting infested wood through a wood chipper effectively destroys spotted lanternfly egg masses, and researchers recommend the practice for reducing the potential spread of the pest.
The return of the screwworm to Florida in 2016 was a surprise, but entomologists with the USDA and local, state, and international partners were prepared to respond. A new, in-depth report in the Journal of Medical Entomology shares a detailed account of their work re-eradicating the pest via the sterile insect technique—plus new lessons learned along the way.
