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.
