Background Bacillus thuringiensis (Bt) Cry toxins have specific toxicity to susceptible insects. They are being used in transgenic plants or spray to control insect pests in agriculture [1, 2, 3]. Cry3A toxins are used extensively for biological control of coleopteran larvae [4, 5]. A Bt886-Cry3Aa gene that exhibited a high activity against Coleoptera insects isolated Our laboratory. Insect bio...

Wetested thehypothesis that contact pheromonesmediatemate recognition inPrionus californicusMotschulsky, a species of longhorned beetle (Coleoptera: Cerambycidae) in the primitive subfamily Prioninae. Males attempted to mate with live females only after contacting themwith their antennae, and 80% of males showed an identical response to freshly killed females. Males did not attempt to mate with...

An ongoing study of the longhorned beetle fauna in cloud forests Cusuco National Park revealed multiple additions to Honduran fauna. Four new species are described: Heterachthes caceresae sp. nov. (Cerambycinae, Neoibidionini), Oreodera kawasae (Lamiinae, Acrocinini), Phrynidius guifarroi Apomecynini), and Strangalia lunai (Lepturinae, Lepturini). Additionally, Lagocheirus parvulus Casey, 1913 ...

Exotic forest pests cost China and the United States billions of dollars each year. Current regulatory systems worldwide are overwhelmed with the increasing volume of international trade. Trade in nursery stock, wood products, pallets and dunnage have proven the most common means of transport for exotic forest pests. Despite our best efforts, pests such as chestnut blight, gypsy moth, Dutch elm...

The aromatic polymer lignin protects plants from most forms of microbial attack. Despite the fact that a significant fraction of all lignocellulose degraded passes through arthropod guts, the fate of lignin in these systems is not known. Using tetramethylammonium hydroxide thermochemolysis, we show lignin degradation by two insect species, the Asian longhorned beetle (Anoplophora glabripennis) ...

The ectoparasitic mite Pyemotes tritici (Lagrèze-Fossat & Montané) (Acari: Pyemotidae) caused paralysis and reduced longevity in eucalyptus longhorned borer, Phoracantha semipunctata F., under laboratory rearing conditions. Application of dusting sulfur to logs that contained pupating borers greatly reduced densities of mites on emerging adult beetles and increased beetle survivorship. Uniform ...
