Researchers' Proposals

Assessment of pesticide side-effects on natural enemies and its

possible use for species separation

There is practically no information on the pesticide tolerance of the

recently recognized Chrysoperla species and also their

identification is problematic. The following research project would

be of importance for IPM:

1. Testing of pesticides on natural enemies (different sibling

species of the Chrysoperla carnea complex, Cocccinella

septempunctata, etc.) to find selective preparations and save them

from pesticide applications.

2. Measuring of AChE activity of the sibling species of Ch. carnea

complex to distinguish them from each other (possibility of a

biochemical species separation).

3. Study of the European distribution of the Ch. carnea complex.
