Wasp parasitoid disruption of host development: implications for new biologically based strategies for insect control.
TLDR
An overview of the manipulative capabilities of wasp-injected calyx fluid containing polydnaviruses and venom, as well as the Parasitoid larva and the teratocytes that originate from the serosal membrane that surrounds the developing embryo of the parasitoid are presented. Expand
Ecdysteroid titers and developmental expression of ecdysteroid-regulated genes during metamorphosis of the yellow fever mosquito, Aedes aegypti (Diptera: Culicidae).
TLDR
Ecdysteroid titers and expression profiles of ecdysone-regulated genes were determined during the last instar larval and during the pupal stages of Aedes aegypti to lay a solid foundation for future studies on the hormonal regulation of development in mosquitoes. Expand
Molting in workers of the Formosan subterranean termite Coptotermes formosanus.
TLDR
The Formosan subterranean termite, Coptotermes formosanus, with its huge colonies, is a major urban pest in several southern states and Hawaii as well as in South Asia and the high juvenile hormone III titer may also be involved in causing defaunation. Expand
Effects of Parasitism by the Braconid Wasp Cotesia congregata on Metabolic Rate in Host Larvae of the Tobacco Hornworm, Manduca sexta.
TLDR
Examination of growth rates, gas exchange patterns and energy metabolism of tobacco hornworm larvae parasitized by the braconid wasp Cotesia congragata found no correlation with hemolymph ecdysteroid titers, contrary to initial expectation. Expand
Host-parasitoid interactions relating to penetration of the whitefly, Bemisia tabaci, by the parasitoid wasp, Eretmocerus mundus
TLDR
Results provide new information regarding the timing and dynamics of parasitoid oviposition and egg hatch as related to larval penetration, parasitoids-induced changes in whitefly development, molting hormone titers and the process of capsule formation. Expand
The nymphal-adult molt of the silverleaf whitefly (Bemisia argentifolii): Timing, regulation, and progress.
TLDR
This study is the first to describe the regulation, timing, and progress of the nymphal-adult molt and of the structural changes that accompany nympha-adult metamorphosis in the SLWF. Expand
Methods and Markers for Synchronizing Maturation of Fifth-Stage Larvae and Pupae of the European Corn Borer, Ostrinia nubilalis (Lepidoptera: Pyralidae)
TLDR
In insects reared under a photoperiod of LD 16:8 and 30°C, the ocellar pigment became diffuse and disappeared during the first 24 h of the pupal stage, and the future compound eyes looked like very dark spheres. Expand
Timing and ecdysteroid regulation of the molt in last instar greenhouse whiteflies (Trialeurodes vaporariorum).
TLDR
This study is the first to investigate the timing and regulation of the molt, to monitor ecdysteroid titers in precisely staged 4th instar whiteflies and to examine the internal anatomical changes associated with metamorphosis in these tiny homopteran insects. Expand
Mode of action of methoprene in affecting female reproduction in the African malaria mosquito, Anopheles gambiae.
TLDR
The data suggest that ecdysteroid titers are correlated with Vg synthesis, and methoprene affects vitellogenesis by modulating ecdysone-regulated action in A. gambiae. Expand
The broadly insecticidal Photorhabdus luminescens toxin complex a (Tca): Activity against the Colorado potato beetle, Leptinotarsa decemlineata, and sweet potato whitefly, Bemisia tabaci
Toxin complex a (Tca), a high molecular weight insecticidal protein complex produced by the entomopathogenic bacterium Photorhabdus luminescens, has been found to be orally toxic to both the ColoradoExpand
