The clover seed weevils Apion fulvipes Geoffroy, and Apion trifolii L., (Coleoptera: Apionidae) cause major losses to seed production of white clover (Trifolium repens L.) and red clover (Trifolium pratense L.), respectively. Clover is important as animal forage and an alternative to inorganic fertilizers. Because clover is mainly pollinated by bees, the use of insecticides in Cited by: 3. The clover seed weevils Apion fulvipes Geoffroy, and Apion trifolii L., (Coleoptera: Apionidae) cause major losses to seed production of white clover (Trifolium repens L.) and red clover. Greenhouse tests on feeding preferences of larvae and adults of the clover root curculio, Sitona hispidula (F.), for 5 forage legumes indicated that adults preferred white, alsike, and red clover.

Crown rot is a soft decay of flowers and leaves, often in the crown. Affected parts are often covered with a downy gray mold. Affected parts are often covered with a downy gray mold. Botrytis development is encouraged by high humidity, poor air circulation, crowded plants, underfertilization, and a night temperature below 62°F. I focused on beetles rather than moths (though I still saw 8 new moths!) and recorded 33 species, including the whirligig Gyrinus paykulli and the saproxylic species Euglenes oculatus.I had been hoping to see the scarab Odonteus armiger, especially a male with its rhino horn, but it was not to beetle is a familiar sight to the Bucks moth-ers when they’re light-trapping on chalk. Padmavati Manchikanti, in Nano-Biopesticides Today and Future Perspectives, Abstract. Crop damage from pathogens and pests is a worldwide problem.
