Larval performance was studied by following larvae enclosed in cages from newly moulted second instars to third instars in the field.
Mistakes are rare, since only in one case, were two wasp larvae (both first stage) found in a single ant.
The above study suggested that dipterous larvae might be good test insects since their availability was fairly steady throughout the year.
A simplified table for staging anuran embryos and larvae with notes on identification.
Large quantities of each species should be collected, and also larvae in all their stages.
Of these larvae 11 hatched after stimulation and the remainder died.
Using these methods, the resistance status of parasite populations can be analysed by testing representative numbers of individual nematode larvae or adults.
Possibly emerging young larvae still sustained some nutritive reserves from the egg stage.
