Six new species of Agrilus Curtis, 1825 with affinities to the emerald ash borer, Agrilus planipennis Fairmaire, 1888, are described from the Oriental Region: Agrilus crepuscularissp. n. (Malaysia); Agrilus pseudolubopetrisp. n. (Laos); Agrilus sapphirinussp. n.(Laos); Agrilus seramensissp. n.(Indonesia); Agrilus spineussp. n. (Malaysia); and Agrilus tomentipennissp. n. (Laos). The genus Sarawa...

Coffee is one of the most important agricultural commodities in the world and is grown in more than 50 countries throughout the tropics. Several insect pests have been reported in coffee, the most important being the coffee leaf miner, the coffee berry borer, and the coffee stem borers. The basic biology of these insects is discussed.

Efforts are being made to express toxin genes from the bacterium, Bacillus thuringiensis (Bt) in chickpea for minimizing the losses due to the pod borer, Helicoverpa armigera. However, there is an apprehension that acidic exudates in chickpea leaves may influence the protoxin-toxin conversion in the insect midgut, and thus, reduce the efficacy of Bt toxins. Therefore, we studied the influence o...

Chemical and biological insecticides have been frequently used in sugarcane fields to control insects-pests, including the borer, Diatraea saccharalis. Among products used, those based on chlorantraniliprole Metarhizium anisopliae entomopathogenic fungus, stand out. Euborellia annulipes is an insect of order Dermaptera considered a potential predator borer eggs. This study aimed evaluate direct...

Abstract A field experiment was conducted to assess the efficacy of pre-mixture pheromone formulation containing ethyl-4-methyl octanoate and 4-methyl-5-nonanol against rhinoceros beetle weevil stem borer. Four doses pheromone, i.e., 1 mL/2 ha, mL/3 mL/4 mL/8 were tested following a randomized block design with five replications. mock treatment using mL pure water used as comparison. The result...

Events have been represented as part of the lexicon (Grimshaw 1990; Pustejovsky 1991), as part of argument structure (Davidson 1967; Higginbotham 1985; Kratzer 1994), in aspectual projections (Tenny 1994; Borer 1994; Travis 1991, 1994) and as a property of Feature Checking (van Hout 1996). We argue that the Feature Checking account defined on Event related projections captures morphological var...

Here, we report the genome of Fusarium euwallaceae strain HFEW-16-IV-019, an isolate obtained from Kuroshio shot hole borer (a Euwallacea sp.). These beetles were collected in Tijuana, Mexico, from elm trees showing typical symptoms of Fusarium dieback. The final assembly consists of 287 scaffolds spanning 48,274,071 bp and 13,777 genes.

1. Ants are important predators in agricultural systems, and have complex and often strong effects on lower trophic levels. Agricultural intensification reduces habitat complexity, food web diversity and structure, and affects predator communities. Theory predicts that strong top-down cascades are less likely to occur as habitat and food web complexity decrease. 2. To examine relationships betw...
