The parasitoids were given 4 d to oviposit
on the nymphs, after which they were removed from the cages.
javanus females are synovigenic; that is, they emerge with high numbers of immature eggs and only few mature eggs but continue to produce eggs throughout the adult stage, implying that females can start to oviposit
in host caterpillars just after emergence.
19 eggs per day after stored for 5 days and 8.3 eggs
albina exhibits kleptoparasitic behaviour and oviposits
preferentially in partially buried dung balls of a single species out of a selection of possible local hosts.
For Jayasingh and Taffe (1982) the cells closest to the nests' entrance present a higher rate of parasitism due to higher exposure and also because parasitoids can oviposit
through the closed nest and cell partitions (Coville, 1982).
Size of clutch based on oviposited
eggs averaged 9.8 [+ or -] 2.2 (range 4-14, n = 39) and averaged 9.5 [+ or -] 2.1 (range 414, n = 49) when counts of corpora lutea (including those that oviposited
) were included.
All the engorged sandflies in two groups were given sugar syrup every morning and observed until they oviposited
3) suggested that oviposition was not affected until temperatures on the cool and moist side were below 14[degrees]C: they curtailed oviposition rather than oviposit
in unfavorable conditions (Fig.
castoris parasitize the host, and the life cycle is unique in that it is completed in its entirety upon the host, save for three brief periods (Wood 1965): gravid females briefly abandon their hosts to oviposit
on debris within beaver lodges or burrows where their eggs hatch after ~32 days; emergent larvae subsequently migrate to an available host and undergo three instar stages of development, with mature third-instars leaving the host to pupate in elevated soil of lodges and burrows, and adults emerging after 11-22 days, depending on ambient temperature.
Following copulation, couples normally remained in tandem to oviposit
. A ratio of 6:1, tandem oviposition to single female oviposition, n=56, was found.
Of course, the initial recolonization of recently burned savanna is necessary to ensure butterflies have a chance to oviposit
Tobacco budworm moths oviposit
on CU 165 leaves, but most of the newly hatched budworm larvae die.
