Thesis.  aTest treatments of a nuclear polyhedrosis virus (NPV) and the insecticides carbaryl and methomyl were applied to naturally occurring field populations of the velvetbean caterpillar (VBC), Anticarsia gemmatalis Hubner, on soybean to determine their efficacy in reducing VBC larval populations and their effect on naturally occurring epizootics of the entomogenous fungus Nomuraea rileyi (Farlow) Samson. Virus treatments consisted of 30, 58, 58 plus 0.5 lbs of benomyl, and 115 larval equivalents (LE)/acre. Insecticde treatments consisted of carbaryl at 0.25, 0.06, 0.03, and 0.003 lb of active ingredients (AI)/acre and methomyl at 0.25, 0.06, 0.03, and 0.006 lb AI/acre. Laboratory studies were also conducted to determine efficacy of the virus and its persistence inthe field. All viral doses were effective in suppressing VBC populations below damaging levels even at 19 days after one application of NPV. Most larval mortality occurred at 6, 7, and 8 days spraying, but laboratory tests revealed that the infected larvae ceased feeding after the 4th day. Tests on viral persistence of activity in the field showed that the NPV retained 65% to 70% of its original activity 7 days after.  abiological control  achemical control  aentomology  aAnticarsia Gemmatalis  aBaculovirus  aControle Biológico  aControle Químico  aEntomologia  aFungo  aInseticida  aNomuraea Rileyi  aSoja  aFungus  aInsect pest  aInsecticide  aInseto praga  aNuclear polyhedrosis virus  aSoybean  aVírus da poliedrose nuclear
