Voorbeelden van larvae

• A single leaf was placed in each pot containing larvae and this was replaced every second day.

• The window opens when aphids are abundant enough for sufficient survival of larvae developing from eggs.

• At the same time, third instar larvae were transferred to the upper surface of the first fully opened mature leaf of individual plants.

• It was defined as the period of time until the first eggs with fully-developed first instar larvae were visible in different female age classes.

• Attention has focused almost exclusively on adult beetles, probably because their larvae are conspicuously missing from tropical foliage.

• An effect of larval food-plant on adult life-span was found with greater longevity in females that had as larvae consumed exclusively lodgepole pine foliage.

• Cattle were infested artificially with 2 x 10000 larvae and the engorging adult females counted.

• Possibly emerging young larvae still sustained some nutritive reserves from the egg stage.

• Using these methods, the resistance status of parasite populations can be analysed by testing representative numbers of individual nematode larvae or adults.

• Of these larvae 11 hatched after stimulation and the remainder died.

• Large quantities of each species should be collected, and also larvae in all their stages.

• A simplified table for staging anuran embryos and larvae with notes on identification.

• The above study suggested that dipterous larvae might be good test insects since their availability was fairly steady throughout the year.

• Mistakes are rare, since only in one case, were two wasp larvae (both first stage) found in a single ant.

• Larval performance was studied by following larvae enclosed in cages from newly moulted second instars to third instars in the field.
