Voltinism and the Induction of Aestival Diapause in the Colorado Potato Beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)
Field studies over 3 yr demonstrated that overwintering populations of the Colorado potato beetle in upstate New York and on Long Island are composed of adults from both the first and second summer generations. The two populations from the climatically different regions differ in their responses to environmental factors that influence voltinism. The critical photoperiod for aestival diapause in...
متن کاملVoltinism and Laboratory Rearing of Microvelia Hinei (heteroptera: Gerromorpha: Veliidae)
Voltinism in Microvelia hinei was studied in southern Illinois during 1989 and 1990. This species apparently overwintered as adults, which became active in late April; adults were last collected in late September. First instars were found from mid-May to late June, second instars from early-May to late October, third instars from mid-May to mid-July, fourth instars from mid-May to mid-August, a...
متن کاملInduction of pupal diapause and photoperiodic sensitivity during early development of Sarcophaga peregrina larvae.
Effects of long day and short day treatments during the embryonic and larval stages on induction of pupal diapause were studied on a diapausing race of Sarcophaga peregrina. Two long day (15L 9D) cycles during 2 days before or after the larviposition completely stopped the induction of pupal diapause on larvae which grow in short day condition before and after the long day treatment. The sensit...
متن کاملAdaptive latitudinal cline of photoperiodic diapause induction in the parasitoid Nasonia vitripennis in Europe.
Living in seasonally changing environments requires adaptation to seasonal cycles. Many insects use the change in day length as a reliable cue for upcoming winter and respond to shortened photoperiod through diapause. In this study, we report the clinal variation in photoperiodic diapause induction in populations of the parasitoid wasp Nasonia vitripennis collected along a latitudinal gradient ...
متن کاملPhotoperiodic Control of Diapause Induction in the Larva of Lucilia Caesar
Diapause in insects is herein defined as a state of arrested growth and development which, unlike quiescence, persists until the animal undergoes a certain, well-defined sequence of physiological events that enables development to be resumed. In the green blowfly, Lucilia caesar L., a facultative diapause occurs in the 3rd-instar larva after cessation of feeding but before puparium formation. T...
