Feeding substrates to black coconut bunch weevil, Homalinotus coriaceus (Gyllenhal) (Coleoptera: Curculionidae), rearing in laboratory

A meridic diet for laboratory rearing of Red Palm Weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae)

The red palm weevil (RPW) Rhynchophorus ferruginous (Olivier) was fully developed and reared on a meridic diet consisting of agar, distilled water, commercial yeast as well as laboratory produced amino and fatty acid rich brewer’s yeast (Saccharomyces cerevisiae), wheat meal, corn flour, benzoic acid, ascorbic acid, sorbic acid, vitamin mix and tetracycline hydrochloride. A group of weevils rea...

Size-dependent feeding and reproduction by boll weevil (Coleoptera: Curculionidae).

The considerable variation in adult size of the boll weevil, Anthonomus grandis grandis Boheman, has been well documented, but the influences of adult size on reproductive rate are not known. We examined the relationship between the size of boll weevils and their feeding and oviposition. Weevils weighed to the nearest milligram were grouped into five categories based on pupal weight: < or =5, 6...

Virulence of entomopathogenic nematodes to pecan weevil larvae, Curculio caryae (Coleoptera: Curculionidae), in the laboratory.

The pecan weevil, Curculio caryae (Horn), is a key pest of pecans in the Southeast. Entomopathogenic nematodes have been shown to be pathogenic toward the larval stage of this pest. Before this research, only three species of nematodes had been tested against pecan weevil larvae. In this study, the virulence of the following nine species and 15 strains of nematodes toward fourth-instar pecan we...

Sunflower Resistance to the Red Sunflower Seed Weevil (Coleoptera: Curculionidae)

Response of cranberry weevil (Coleoptera: Curculionidae) to host plant volatiles.

The oligophagous cranberry weevil, Anthonomus musculus Say, causes economic losses to blueberry growers in New Jersey because females deposit eggs into developing flower buds and subsequent larval feeding damages buds, which fail to produce fruit. A cost-effective and reliable method is needed for monitoring this pest to correctly time insecticide applications. We studied the behavioral and ant...
