Egg development and larval behavior of phanerotoma flavitestacea hymenoptera braconidae when parasitizing the eggs of anagasta kuehniella lepidoptera pyralidae after reaching different stages of development



Egg development and larval behavior of phanerotoma flavitestacea hymenoptera braconidae when parasitizing the eggs of anagasta kuehniella lepidoptera pyralidae after reaching different stages of development



Entomophaga 24(3): 237-246



When lepidopterous eggs of varied ages (1 h-5 days) are offered to parasitic females of P. flavitestacea Fisch, where the parasitic egg is deposited depends on the developmental stage of the host egg at the time of oviposition. When the host egg is 1 h-3 days old, the laying takes place in the yolk. If the parasite egg is deposited in a 4 day old or an older host egg, it is directly laid in the host embryo. It seems that the penetration of the parasitic egg or larva is only a passive movement caused by the migration of the yolk into the midgut of the host embryo. These different points and the effect of the sting of the ovipositor on the host embryo, the nature of the elimination of the supernumerary larva, are discussed.
