Histones are the major protein component of chromatin structure. The histone family is made up of a quintet of proteins, four core histones (H2A, H2B, H3 & H4) and the linker histones (H1). Spacers are found between the coding regions. Among insects this quintet of genes is usually clustered and the clusters are tandemly repeated. Ribosomal DNA contains a cluster of the rRNA sequences 18S, 5.8S...

The Ciidae genus Anoplocis was established by Makoto Kawanabe (1996) based on the type species Ennearthron poriae Nakane & Nobuki, 1955 from Japan. Additionally, he described the Japanese species Anoplocis ryukyuensis Kawanabe, 1996. However, the name Anoplocis was previously proposed by Arthur M. Lea (1913) for a genus of true weevils (Coleoptera: Curculionidae), with its type species Anoploci...

This study investigated relationships between climate and historic spruce beetle, Dendroctonus rufipennis Kirby (Coleoptera: Curculionidae), outbreaks in northern and southeastern Utah and western Colorado between 1905 and 1996. A chronology of outbreak years was constructed from historic records, research papers, newspapers, and other sources of information. Historic climate data for the regio...

We evaluated the attraction of Monochamus alternatus Hope (Coleoptera: Cerambycidae), Dryocoetes luteus Blandford and Orthotomicus erosus Wollaston (Coleoptera: Curculionidae: Scolytinae) to multiple-funnel traps baited with the pine volatiles, ethanol and (+)-α-pinene and the bark beetle pheromones, ipsenol and ipsdienol. M. alternatus were attracted to traps baited with ethanol and (+)-α-pine...

The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Curculionidae: Coleoptera), is not native to the United Arab Emirates (UAE). Since its arrival in 1985, it has been causing major damage to date palm trees. A primary control strategy has been the use of pheromone baited traps. The objectives of this study were to determine the quantity of bait, and the best trap color, to obtain the max...

We evaluated the efÞcacy of the systemic insecticides dinotefuran, emamectin benzoate, Þpronil, and imidacloprid for preventing attacks and brood production of southern pine engraver beetles (Coleoptera: Curculionidae: Scolytinae) and wood borers (Coleoptera: Cerambycidae) on standing, stressed trees and bolt sections of loblolly pine, Pinus taeda L., in eastern Texas. Emamectinbenzoate signiÞc...

Cold-induced mortality has historically been a key aspect of mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), population control, but little is known about the molecular basis for cold tolerance in this insect. We used RNA-seq analysis to monitor gene expression patterns of mountain pine beetle larvae at four time points during their overwintering period-early-...

To investigate the mechanisms of water hyacinth (Eichhornia crassipes) control, an efficient Baysian model system is required. Although deterministic models have been used to predict organism control, such models suffer from the inability to account for stochasticity in a system Entomologists and conservationists in related fields have offered multidisciplinary and multi‐institutional computer ...

BACKGROUND The tribe Centistini includes three genera, Allurus, Centistes and Centistoides (Stigenberg et al. 2015). They are solitary endoparasitoids of adults and final instar larvae of beetles from the family Curculionidae (Jackson 1920, Aeschlimann 1980, Tobias 1986). NEW INFORMATION In this paper we present a key, molecular data (standard DNA barcode, CO1) and images of the two species o...

The South African Sugarcane Research Institute (SASRI) is researching an Area-Wide Integrated Pest Management (AW-IPM) strategy against sugarcane thrips, Fulmekiola serrata (Kobus) (Thysanoptera: Thripidae). Unique monitoring techniques successfully implemented provided faunal complexes that might include natural enemies within leaf spindles. Twentyeight Thysanoptera taxa from three families, n...
