Примеры grasshopper

• However, in non-outbreak years, the overall population dynamics of grasshoppers appears to be influenced significantly by a suite of natural enemies attacking successive developmental stages.

• Some experiments were carried out on this subject with some of the common grasshoppers.

• Fungous diseases of adult grasshoppers can be ignored, for in normal years the percentage of infestation is very low, probably less than one per cent.

• All control insects survived the 9-day period of observation, while 30-95% of parasitized grasshoppers died, depending on the species (table 1).

• All branches of each plant and the ground in each square were carefully examined in order to detect the presence of any grasshopper.

• Secondary defence in the grasshopper does not occur if the spermathecae are surgically removed prior to mating.

• These grasshoppers usually occurred on leaves or branches of trees, and were flushed by the macaques' movements.

• Individual larvae were transferred with a camel's hair brush into the ruptured tympanum of each grasshopper.
