Mouthpart morphology and stylet penetration of host plants by the glassy-winged sharpshooter, Homalodisca coagulata, (Homoptera: Cicadellidae).
The ultrastructural morphology of the mouthparts of the glassy-winged sharpshooter, Homalodisca coagulata, and method of plant penetration was examined using light microscopy, scanning electronExpand
The long summer: pre-wintering temperatures affect metabolic expenditure and winter survival in a solitary bee.
The impact of climate change on insect populations depends on specific life cycle traits and physiological adaptations. The solitary bee Osmia lignaria winters as a pre-emergent adult, and requires aExpand
Cuticular lipid composition of Heliothis virescens and Helicoverpa zea pupae
Abstract The cuticular lipids of laboratory-reared tobacco budworms, Heliothis virescens (Fabricius), and corn earworms, Helicoverpa zea (Boddie), pupae were characterized. Quantities of cuticularExpand
LIFE CYCLE OF LABORATORY-REARED TOBACCO HORNWORMS, MANDUCA SEXTA, A STUDY OF DEVELOPMENT AND BEHAVIOR, USING TIME-LAPSE CINEMATOGRAPHY
1. Time-lapse cinematography was used with laboratory-reared specimens of M. sexta to obtain information on and timing of behavioral activities.2. Insects used in this study were selected as the mo...
The composition of the cuticular lipids from nymphs and exuviae of the Silverleaf Whitefly, Bemisia argentifolii
Abstract The surface lipids of Bemisia argentifolii Bellows and Perring (Homoptera: Aleyrodidae) nymphs and exuviae were characterized. The identification and distribution of lipids were determinedExpand
Stylet Penetration by Bemisia argentifolii (Homoptera: Aleyrodidae) into Host Leaf Tissue
Abstract Silverleaf whitefly, Bemisia argentifolii Bellows & Perring, adults and nymphs feed on the phloem tissue of host plant leaves. Infested leaves were rapidly fixed to prevent the insects fromExpand
External lipids of adults of the giant whitefly, Aleurodicus dugesii
Abstract The external lipids of male and female adults of the giant whitefly, Aleurodicus dugesii , were found in three forms; as cuticular lipids, as waxy particles, and only on the females, as waxyExpand
Characterization of triacylglycerols from overwintering prepupae of the alfalfa pollinator Megachile rotundata (Hymenoptera: Megachilidae).
Alfalfa leafcutting bees, Megachile rotundata (F.), overwinter as prepupae. The internal lipids were extracted from prepupae that had been wintered at 4 degrees C for 7 months. Megachile rotundataExpand
Susceptibility of Upland Cotton Cultivars to Bemisia tabaci Biotype B (Homoptera: Aleyrodidae) in Relation to Leaf Age and Trichome Density
Abstract The relationships between leaf trichome densities, leaf age, and sweetpotato whitefly, Bemisia tabaci (Gennadius) biotype B, infestations of 13 upland cotton, Gossypium hirsutum L.,Expand
One-step purification and properties of a two-peptide fatty acid synthetase from the uropygial gland of the goose.
Cell-free extracts from the uropygial gland of goose catalyzed the incorporation of malonyl-CoA into normal fatty acids and methylmalonyl-CoA into multimethyl branched acids with NADPH as theExpand
