b) Coconut rhinoceros beetle life stages: E = eggs, L1-3 = larval instars 1-3, PP = prepupae

Dallwitz R, Wardhaugh KG (1984) Overwintering of prepupae
of Lucilia cuprina (Diptera: Calliphoridae) in the Canberra region.
In insect and butterflies it initiates and maintains metamorphosis from larvae to prepupae
and pupae (Bathori et al.
Trees were harvested in February and March with insects still at their overwintering larval or prepupae
stage about a centimeter inside the phloem.
About 60 tons of fresh prepupae
can be self-harvested from one 100,000-hen caged layer house in five months.
carpocapsae nematodes in moist soil, along with larvae of western corn rootworm and prepupae
of Colorado potato beetle--two of American agriculture's most notorious pests.
Fourth instar larvae transform into prepupae
SURVIVAL (%) AT VARIOUS TEMPERATURES OF THE DIFFERENT INSTARS, TOTAL LARVAL STAGE, PREPUPAE
, PUPAE AND TOTAL PRE-IMAGINAL STAGE OF HARMONIA AXYRIDIS AND CHRYSOPERLA EXTERNA FED ON RHOPALOSIPHUM PADI.
, pupae, and adults of a Coleoptera were found under the bark of the trunks, and larvae in P.
The mortality of the first instar larvae was 95%, and that of the prepupae
and pupae reached 100%.
Likewise the survival rates from prepupae
to pupae (Su2) of F.
At the second sampling date, prepupae
were found and 7.
