The nutrition during pupation
and after adult enclosure affects offspring rates to a greater extent than the nutrition during the larval stage (partial eta squares: 0.
Beetles in their larval state bore large holes in long bones to use the inner cavity as a pupation
PHOTO : Corrugated paper rings, such as this one held by entomologist Leslie Lewis, form pupation
sites for corn borer larvae during laboratory rearing.
Buckeye-butterfly larvae dining on such plants ate about 15 percent more than their counterparts eating plants grown at today's carbon dioxide levels, took 10 percnt longer to reach pupation
and were visibly weaker, report ecologist Eric Fajer and his co-workers at Harvard University.
1 mg/mL of 20E adversely affected survival and pupation
of P xylostella larvae.
One week after pupation
, the cocoons were harvested and thirty cocoons in good condition were cut open from each batch.
to the adult stage typically takes 9 to 15 days under normal temperatures.
On every alternate day, the water from the culture tray was changed carefully until pupation
All larvae were exposed till pupation
and mortality was recorded at 24 h intervals.
Most EAB larvae were in their ultimate instar and near pupation
Raised commercially, BSF larvae are self-harvesting at the time of pupation
, crawling away from their contained food source and into strategically located containers allowing large quantities to be collected and processed.
After the host has been infected, larval and pupal development of male parasitoids in the two orders follow a similar pattern of endoparasitic developmental stages, pupation
and the emergence of a free-living adult.
