Entomological Society of America The sweet potato weevil, Cylas formicarius (Fabricius), is the most serious pest of sweet potato around the world, damaging sweet potatoes in the field and in storage. Because the larval period is spent within vines or tubers, and the adults are nocturnal, chemical control frequently is not effective. Mass trapping using synthetic pheromones has suppressed populations of sweet potato weevil males in several countries, but it has not reduced the damage...

Ensuring the monarch butterfly's survival by saving its milkweed habitat could result from U.S. Department of Agriculture (USDA) studies initially intended to improve detection of boll weevils with pheromone traps.

By Garcia-Robledo, Carlos Staines, Charles L INTRODUCTION IT IS suggested that rolled-leaf hispine beetles (Hispinae, Coleoptera) and plants from the order Zingiberales maintained a highly specialized plant-herbivore interaction for >60 My. The evidence supporting this old and conservative interaction are herbivory marks found on leaves of the genus Zingiberopsis (Zingiberaceae) from the latest Cretaceous and early Eocene. This fossil herbivory was described as the ichnotaxon...

By Mark Prado, The Marin Independent Journal, Novato, Calif. Jun. 15--MARIN WATER officials are considering unleashing tick-size weevils to combat an alien plant that has invaded Mount Tamalpais reservoirs. The slim, green non-native Eurasian watermilfoil, a plant sometimes found in home aquariums, has taken root in the floor of five Marin Municipal Water District reservoirs, triggering concerns about water quality. One solution under study is importing a weevil -- an aquatic beetle...

By PEGGY HARRIS LITTLE ROCK, Ark. - A tiny pest that has caused billions of dollars in damage to cotton fields nationwide has nearly been eradicated from Arkansas fields, officials said. Danny Kizer, executive director of the Arkansas Boll Weevil Eradication Program, said Monday that the boll weevil population has been reduced at least 99 percent since the effort began 10 years ago. The insect should be all but eliminated from Arkansas cotton fields in two years, he said. "It's just a...

A weevil is a beetle from the Curculionoidea superfamily. There are over 60,000 species in several families, mostly in the family Curculionidae (the true weevils). They are typically small, measuring less than ¼ inch (6mm), and herbivorous. Due to the shape of their heads, weevils are commonly known as snout beetles. Weevils are destructive to crops. One example is the grain or wheat weevil (Sitophilus granarius), which damages stored grain. The boll weevil (Anthonomus grandis)...
