For Ash-Dependent Insects, Some Plants Make Good Alternatives—But Others Don’t
With ash trees decimated by the emerald ash borer, where do other insects that depend on ash go? A new study shows landscape managers that choosing the right replacements for ash is critical for such ash-reliant native insects.
Honey Bee Heat Warms Up Fellow Pollinators for Early-Season Blooms
An incubator that draws excess heat from a honey bee hive warms up managed Osmia lignaria bees so they can pollinate early-blooming fruit trees such as cherry, apple, and almond. A new study shows the hivetop incubators are effective, with little effect on the honey bee hive temps below.
Why Larvae of One Wasp Species Often Eat Their Siblings
Sibling rivalry takes a grim turn in the parasitoid wasp species Isodontia harmandi, as larvae commonly cannibalize their nest mates. A new study suggests the stronger larvae eat their siblings both to grab an easy meal and to reduce competition for the food provided by their mother.
International IPM Program Drives Sustainable Management of Tomato Leafminer
Since 2012, the Centre for Agriculture and Bioscience International's Plantwise program has guided growers in 10 Latin American countries on managing Tuta absoluta, a devastating lepidopteran pest of tomatoes, and substituting or complementing chemical control with more sustainable strategies.
