4. Describe the incident identified in the study (e.g. study demonstrates an increased risk to non-Hodgkin's Lymphoma after exposure to pesticide X)

A repeat dose dietary exposure test to honey bee larvae was conducted using MON 0139 (MON 0139 = 46.1% a.e.; glyphosate IPA salt in water) using dietary doses of 5.1, 12.8, 31.9, 80 and 200 Aug a.s./larva (corresponding to 11.0, 27.5, 68.7, 172 and 429 Aug product/larva) + positive negative control gps. (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. The respective NOED was 80 Aug a.s./larva and the corresponding NOEC was 505 mg a.s./kg diet.
