Research on dung beetle behavior shows many species, especially smaller ones, choose a "sit and wait" strategy for finding food, while only larger ones actively search for food by following animals. A pair of biologists suggest this behavior is a resource-partitioning strategy to reduce competition for scarce food.
Mites in the genus Tropilaelaps could follow in the footsteps of Varroa mites as significant threats to honey bees if they were to expand their range. A new test using analysis of the "melt curves" of DNA samples can discern the four known Tropilaelaps species and could be an important tool in surveillance for the mite pests in apicultural settings.
A new study finds that three corn varieties bred for drought resistance also stand up better to the Banks grass mite when drought conditions set in—a potential boon to growers in regions with diminishing water supply.
Researchers in Italy have developed a rapid method for detection of the Asian longhorned beetle, an invasive pest in Europe and North America, using a DNA-detection technique known as loop-mediated isothermal amplification.
