Latest Chrysomelidae Stories
Salt cedar along the waterways of the southern and eastern Panhandle is rapidly being defoliated and dying back, and one Texas A&M AgriLife Research entomologist believes he knows why.
A new study answers a question that has baffled researchers for more than 15 years: How does the western corn rootworm – an insect that thrives on corn but dies on soybeans – persist in fields that alternate between corn and soybeans? The answer, researchers say, has to do with enzyme production in the rootworm gut.
To slow resistance of western corn rootworm beetles to genetically protected crops, much larger 'refuge' acreages of conventional crops have to be planted, 2 experts warn in a paper published in the Journal of Economic Ecology
The corn rootworm is threatening to become agriculture’s worst nightmare as biotech corn is continually losing its resistance to the damaging pests.
Simply by eating the leaves of an invasive tree that soaks up river water, an Asian beetle may help to slow down water loss in the Southwestern United States.
Only five species of these so-called 'flea' beetles, out of a global total of 60, had been found to date in New Caledonia, in the western Pacific.
One of the worst pests of corn in the world, the corn rootworm, may owe its worldwide success partly to its larvae's nasty, sticky blood.
The Scarlet Lily Beetle (Lilioceris lilii) is native to Europe but is now widely found in North America. Larvae damage cultivated lily and Fritillaria plants. Photo by Keith Edkins The beetle family Chrysomelidae, or leaf beetles is a family of over 35,000 species in more than 2,500 genera. Leaf beetles are recognizable by their tarsal formula and distinguished from long-horned beetles (family Cerambycidae) by their short, filiform antennae. Adult and larval leaf beetles feed on all...
PHOTO CAPTION: The common asparagus beetle Crioceris asparagi is an important pest of asparagus crops. Photo by Keith Edkins 2003 The Common Asparagus Beetle (Crioceris asparagi) is an chief pest of Asparagus crops both in Europe and in North America; asparagus is its only food plant. The adult beetles and the larvae strip the needle-like leaves off the asparagus fronds which deprives the plants of the ability to build food reserves for future years. They also damage the shoots, thereby...
PHOTO CAPTION: Goliath Beetle Beetles are one of the main groups of insects. Their order, Coleoptera (meaning "sheathed wing"), has more species than any other order in the entire animal kingdom. Forty percent of all described insect species are beetles (about 350,000 species), and new species are regularly discovered. Estimates put the total number of species at between 5 and 8 million. When J. B. S. Haldane, a British geneticist, was asked what his studies of nature revealed about...
The beetle family Chrysomelidae, or leaf beetles, is a family of over 35,000 species in more than 2,500 genera. Leaf beetles are recognizable by their tarsal formula and distinguished from long-horned beetles (family Cerambycidae) by their short, filiform antennae. Adult and larval leaf beetles feed on all sorts of plant tissue. Many are economically important pests of agriculture, for example the colorado potato beetle (Leptinotarsa decemlineata), the asparagus beetle (Crioceris...
