The shock insect sampling method is derived from the beat cloth method, and was developed to overcome the low performance of latest on sampling small and easy flying insects, like parasitoids of the orders Diptera and Hymenoptera, and to a less extent, predators of the orders Coleoptera and Hemiptera. Instead of beating soybeans to displace insects, supposedly falling onto the beat cloth, a potent and broad spectrum insecticide is applied on a very high rate. The logic is that insects are quichly affected by the insecticide, preventing them from leaving the area, and being killed in minutes, thus falling straight direct to the cloth placed in the soil, between the soybean rows. The cloths were examined 15 minutes after the insecticide application, and the insects transferred to labeled plastic bags for laboratory counting. To compare results obtained by sampling insects with the beat cloth, the shock and the sweep net methods, 5 experiments were set up in Londrina-PR, Brazil. Results indicated that the number of predators collected by both shock and beat cloth are similar, but the shock method extracted a consistently higher number of species of the orders Diptera and Hymenoptera. The experimental data variability, as measured by a binomial model obtained from the dispersion of standart deviation in each sampling date, demonstrated that the shock method has a consistent lower variability index. The sweep net extracted less insects and presented the highest dispersion of the standard deviations. These results can easily been explained due to the less disturbing procedures for insect sampling, on comparing either sweep net or beat clock to the shock method, as plants are not even touched or approached, because insecticide is applied with a bar sprayer long enough to avoid walking close to the sampling area.
