Title: Biology and Pest Potential of Anavitrinella pampinaria (Lepidoptera: Geometridae) in Soybeans1

Weekly sweep-net samples detected a peak population of 0.45 larvae per 10 sweeps in late August and early September. Larvae were rare in similar samples taken in 1980, however. Laboratory studies at 24°C showed that larvae require ca. 24 days to mature and that 42 days are required from egg deposition to adult emergence. Total soybean leaf consumption, 72.3 cm2, was most comparable to that of the velvetbean caterpillar, Anticarisa gemmatalis (Hubner), whereas pupal weight, 109.6 mg, was closest to that of the green cloverworm, Plathypena scabra (F.). Economic injury levels per 10 sweeps are: (R3) 93.0, (R4) 63.6, (R5) 47.4, and (R6) 17.2, indicating that the species is not a significant pest at present.Read More
