(3 reps per gp with 12 larvae per rep) Larvae were fed daily from Day 4 to Day 8. Pupal cumulative mortality was assessed on day 15. Adult emergence rate assessed on day 22. Based on measured dietary doses, the ED50 (adult emergence) was 200 Aug a.s./larva (1262 mg a.s./kg diet). Values for ED10 and EC10 were 75.6 Aug a.s./larva and 477 mg a.s./kg diet, respectively.
