Results and discussion
Any other information on results incl. tables
The LOEL was about 50 ppm for drosophila and in a similar range for house flies. Surviving animals often exhibited morphological abnormalities on adult emergence though pupal development appeared outwardly normal. Mating of adults emerging from sublethal treatment resulted in normal development of second-generation adults of drosophila. This indicates that 2-Imidazolidinone is not a typical sterilant for this species, but rather an inhibitor of drosophila pupal development. On the other hand, 2-Imidazolidinone proved to be a sterilant in female house flies by preventing oviposition. In the milkweed bug, both sexes are rendered sterile on treatment of either young adults or last-instar nymphs.
