Cavichia nom. nov. is proposed for Caragonia Takiya, Cavichioli & Mejdalani, 2003 (Hemiptera: Cicadellidae), preoccupied by Caragonia Gemminger & Harold, 1870 (Coleoptera: Tenebrionidae).

A new species Phymatodes (Poecilium) latefasciatus sp. n. (Coleoptera, Cerambycidae, Cerambycinae, Callidiini) from China is described and illustrated. Features distinguishing the new species from its congeners are presented.

Tumidusternus gen. n., along with Tumidusternusfujianensis sp. n. (Coleoptera, Coccinellidae, Aspidimerini) from China is described and illustrated. A key to the tribe Aspidimerini is given.

In the present work, we examined the insecticidal effect of spinosad, against adults of the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), the confused flour beetle, Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae) on wheat and the larger grain borer, Prostephanus truncatus (Horn) (Col...

The Canadian Entomologist 132: 183 195 (2000) Monoterpenes affected the attraction of three sympatric species of bark beetles (Coleoptera: Scolytidae) to pheromone-baited multiple-funnel traps in stands of lodgepole pine. Catches of Ips pini (Say) in traps baited with its pheromone, ipsdienol, were directly related to the release rates of 3-carene, pphellandrene, and ppinene. Catches of Dendroc...

This study aims to determine the diversity and abundance of beetles make research results a learning medium in form pocket book. type is descriptive using Coleoptera roaming technique method at observation stations. The showed that level was moderate, namely H = 1.08, K 5.50 with number obtained 14 species from 8 families Coleoptera. output this book percentage 82% (Very Appropriate) be used as...

Expressed sequence tag (EST) sequences can provide a wealth of data for phylogenetic and genomic studies, but the utility of these resources is restricted by poor taxonomic sampling. Here, we use small EST libraries (<1,000 clones) to generate phylogenetic markers across a broad sample of insects, focusing on the species-rich Coleoptera (beetles). We sequenced over 23,000 ESTs from 34 taxa, whi...

Use of insecticides can have disruptive effects on the environment. Replacing the chemical compounds in these insecticides with plant materials, however, can be a safe method with low environmental risk. In the current study, chemical composition and insecticidal activities of the essential oil from cardamom, Elettaria cardamomum L. (Maton) (Zingiberales: Zingiberaceae) on the adults of three s...

Dynamics of a cooperative lock-and-key model in genital matching Sitona Germar (Coleoptera: Curculionidae)

Crawling and scraping activity of three stored-product pests, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), and Stegobium paniceum (L.) (Coleoptera: Anobiidae), and two urban pests, Blattella germanica (L.) (Blattodea: Blattellidae) and Cimex lectularius L. (Hemiptera: Cimicidae), were monitored individually by infrared sensors, mi...
