Примеры larva

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

• One day before each new infestation the beans were carefully mixed to achieve a random distribution of host larvae.

• 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.

• To obtain infested fruits, a third instar larva was placed into a small plastic dish (diameter 17 mm, height 11 mm).

• 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.

• One larva was observed to pass through six larval 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.

• Many of these doomed larvae had crawled onto the sides of the vial rather than remaining on the food.

• Captive agoutis and squirrels readily ate larvae when presented without the surrounding endocarp, and preferred larvae to seeds.
