Conteúdo: | Larvae of the velvetbean caterpillar Anticarsia gemmatalis Hubner were collected from soybean (Cdycine (L) Merrili) to determine their population leveis and percentage of infection by the fungus, Norma rileyi (Farlow) Samson. Seasonal population levels of larvae and adults of the carabid predator, Casorm argentaw granulatum (Perty) were determined by pitfall trap collections. The relationship between resurgence of Anticarsia and populations of C41osoma, geocorids, and nabids as influenced by insecticides was studied. Fungus attack began in February during the poci developrnent stage when the third generation of Anticarsia larvae were reaching a peak and 100% of larvae observed on foliage were infected three weeks later. Activity of C's coincided closely with population levels of the third generation of Anticarsia Geocorid and nabid populations were severely affected by monocrotophos and methyl parathion treatments whereas diflubenzuron, a chitin inhibitor, had no apparent deleterious effect.
