Prüfung der Auswirkungen von Pflanzenschutzmitteln auf Nutzarthropoden und deren Einbeziehung in die Zulassung

Tests of side-effects of pesticide on beneficial arthropods and their incorporation into registrationSimulated by the expences of integrated plant protection and based on the plant protection law of the Federal Republic of Germany, a German working group (directed by the Biologische Bundesansalt) since 1970 and an International (WPRS) Working Group since 1974 intiated a systematic study of side-effects of pesticides on beneficial (entomophagous) arthropods. The present status of this work is being reported which intends to obtain guide-lines for tests following standardized principles, which will allow, at first ona voluntary basis, acceptance os a test complementary to the protocol for registration as presently applied. This was officially started in the Fed, Rep. of Germany on October 1, 1975, covering, at first, 3 common and important species of entomophagous parasites (in the laboratory) and one field test developed for the surveys of the fauna of apple trees. Some details of the test, the evaluation of results, and the contributions of experts from member countries of WPRS/IOBC are reported upon. This complementary test, geared from the beginning at an international cooperation, will lesd in all co-operating countries to an enlarged basis for a correct assessment of the total impact of pesticides as it is needed for an effective applicaton of integrated plant protection.
