Disease relevance of Beetles

• The activities of antioxidant enzymes and of luciferase in the prothorax (bright) and abdomen (dim) of luminous larval Pyrearinus termitilluminans (Coleoptera: Elateridae) were measured after previous challenge with either hyperoxia, hypoxia, or the firefly luciferase inhibitor luciferin 6'-methyl ether (LME) [1].
• Acute and sublethal toxicity of novaluron, a novel chitin synthesis inhibitor, to Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) [2].

High impact information on Beetles

• Similar to plants but unique to animals, some bark beetle genera (Coleoptera: Scolytidae) produce monoterpenes that function in intraspecific chemical communication as aggregation and dispersion pheromones [3].
• De novo biosynthesis of the aggregation pheromone components ipsenol and ipsdienol by the pine bark beetles Ips paraconfusus Lanier and Ips pini (Say) (Coleoptera: Scolytidae) [4].
• The possibility of gene tree incongruence in a species-level phylogenetic analysis of the genus Ips (Coleoptera: Scolytidae) was investigated based on mitochondrial 16S rRNA (16S) and nuclear elongation factor-1 alpha (EF-1 alpha) sequences, and existing cytochrome oxidase I (COI) and nonmolecular data sets [5].
• On the other hand, halofenozide is effective on Coleoptera but mildly active on Lepidoptera [6].
• The induction of a complex defense response in Norway spruce by methyl jasmonate application provides new avenues to evaluate the role of resin defenses for protection of conifers against destructive pests such as white pine weevils (Pissodes strobi), bark beetles (Coleoptera, Scolytidae), and insect-associated tree pathogens [7].

Chemical compound and disease context of Beetles

• We conducted laboratory bioassays to determine the toxicity of two systemic insecticides, azadirachtin and imidacloprid, for potential control of A. glabripennis and the cottonwood borer, Plectrodera scalator (F.) (Coleoptera: Cerambycidae), a closely related native cerambycid [8].
• Boll weevil (Coleoptera: Curculionidae) bait sticks: toxicity and malathion content [9].
• Toxicity of diatomaceous earth to red flour beetles and confused flour beetles (Coleoptera: Tenebrionidae): effects of temperature and relative humidity [10].
• Laboratory evaluation of the toxicity of systemic insecticides for Control of Anoplophora glabripennis and Plectrodera scalator (Coleoptera: Cerambycidae) [8].
• Toxicity, persistence, and efficacy of spinosad, chlorfenapyr, and thiamethoxam on eggplant when applied against the eggplant flea beetle (Coleoptera: Chrysomelidae) [11].

Biological context of Beetles

• Juvenile hormone regulation of HMG-R gene expression in the bark beetle Ips paraconfusus (Coleoptera: Scolytidae): implications for male aggregation pheromone biosynthesis [12].
• Phylogeny and evolution of Digitulati ground beetles (Coleoptera, Carabidae) inferred from mitochondrial ND5 gene sequences [13].
• Bale compression and hydrogen phosphide fumigation to control cereal leaf beetle (Coleoptera: Chrysomelidae) in exported rye straw [14].
• Malathion resistance in Tribolium strains and their hybrids: inheritance patterns and possible enzymatic mechanisms (Coleoptera, Tenebrionidae) [15].
• The role of glutathione S-transferases in the detoxification of some organophosphorus insecticides in larvae and pupae of the yellow mealworm, Tenebrio molitor (Coleoptera: Tenebrionidae) [16].

Anatomical context of Beetles

• Isolated perfused Malpighian tubules of the desert beetle Onymacris plana (Coleoptera: Tenebrionidae) have been subjected to cable analysis under the following conditions: control, adenosine 3',5'-cyclic monophosphate (cAMP), corpora cardiaca homogenate (CCH), and high ambient K (130 mM) [17].

Associations of Beetles with chemical compounds

• Studies on the cholesterol ester hydrolase of Trogoderma (Coleoptera) [18].
• Inhibition of digestive proteinases of stored grain Coleoptera by oryzacystatin, a cysteine proteinase inhibitor from rice seed [19].
• To study the structural features of genes for the luciferin-regenerating enzyme (LRE), the entire gene along with 524 bp of upstream sequence was determined from Photinus pyralis (Coleoptera: Lampyridae) [20].
• Luciferase and urate may act as antioxidant defenses in larval Pyrearinus termitilluminans (Elateridae: Coleoptera) during natural development and upon 20-hydroxyecdysone treatment [21].
• Isolation, endocrine regulation and mRNA distribution of the 3-hydroxy-3-methylglutaryl coenzyme A synthase (HMG-S) gene from the pine engraver, Ips pini (Coleoptera: Scolytidae) [22].

Gene context of Beetles

• A similar dicistronic Su(var)3-9/eIF-2gamma transcription unit was found in Clytus arietis, Leptinotarsa decemlineata, and Scoliopterix libatrix, representing two different orders of holometabolic insects (Coleoptera and Lepidoptera) [23].
• Cloning and sequence analysis of Gpdh in Callosobruchus chinensis (Coleoptera: Bruchidae) [24].
• Origin and diversification of hindwingless Damaster ground beetles within the Japanese islands as deduced from mitochondrial ND5 gene sequences (Coleoptera, Carabidae) [25].
• The ATPase-based trees support monophyly for several clades (including Lophotrochozoa, a form of Ecdysozoa, Vertebrata, Mollusca, Bivalvia, Gastropoda, Arachnida, Hexapoda, Coleoptera, and Diptera) but do not support monophyly for Deuterostomia, Arthropoda, or Nemertea [26].
• Colonization and diversification of the species Brachyderes rugatus (Coleoptera) on the Canary Islands: evidence from mitochondrial DNA COII gene sequences [27].

Analytical, diagnostic and therapeutic context of Beetles
