Abstract The mortality of the Alabama argillacea and Chrysodeixis includens (Lepidoptera: Noctuidae) larvae caused by the kaolin inert powder and the entomopathogenic fungus Beauveria bassiana were determined under laboratory conditions. Using the caterpillar submersion method, the CG 138 B. bassiana isolate was more pathogenic to A. argillacea than the CG 70, GC 82, ESALQ 634, and ESALQ 645. All five tested isolates caused similar mortality of C. includens. The mortality of first-instar larvae of A. argillacea and C. includens by feeding on leaf-disc impregnated with B. bassiana (CG 138) and kaolin was also determined. Higher A. argillacea mortalities were observed in the B. bassiana (CG 138) treatments, regardless of the presence of kaolin. However, the activity of kaolin + B. bassiana (CG 138) against C. includens was higher than each ingredient alone, indicating an additive action against C. includes larvae. The mortality of A. argillacea and C. includens larvae treated with kaolin + B. bassiana (CG 138) was similar, and the A. argillacea mortality was higher than that of C. includens with kaolin and B. bassiana (GC 138) separated. The treatment kaolin + B. bassiana (CG 138) is promising for the simultaneous management of these two defoliator pests, mainly A. includes. In addition, the monophagous A. argillacea is more susceptible to both kaolin and B. bassiana (GC 138) than the polyphagous C. includens, suggesting that the nutritional ecology plays an important role in the susceptibility of these defoliator species to alternative insecticides.

Alabama argillacea é uma importante praga desfolhadora da cultura do algodoeiro no Brasil e em países produtores como Austrália, Burkina, China, Índia entre outros. Ela acarreta destruição da área foliar, comprometendo taxas fotossintéticas e a produtividade da pluma e do caroço. Objetivou-se estudar a atratividade e preferência alimentar de A. argillacea a genótipos de algodoeiro. Avaliou-se a atratividade e preferencia alimentar de lagartas do curuquerê em teste de chance de escolha nos genótipos TB 87, TB 85, TB 91 e Grandless. O delineamento experimental foi blocos ao acaso, com quatro tratamentos, 10 repetições e quatro horários de avaliação (15 minutos, 45 minutos, 1 e 2 horas). O genótipo de algodoeiro menos preferido e atrativo para alimentação é o Grandless enquanto que as cultivares TB 87, TB 85, e TB 91 são mais atacadas pelas lagartas. Dentre os genótipos avaliados, a Grandless apresenta menos susceptibilidade em mesmas condições de ataque.

O objetivo do trabalho foi avaliar a ocorrência de lagartas em função do manejo de inseticidas e modos de utilização de cultivares de algodoeiro. O delineamento foi em blocos casualisados, em esquema fatorial 2 x 3, com seis tratamentos e cinco repetições, totalizando 30 parcelas. Os tratamentos foram: 1) Cultivar Nuopal (com inseticida) (100% Bt); 2) Cultivar Deltaopal (com inseticida) (100% não Bt); 3) Cultivar Nuopal centro (80%) e bordadura Deltaopal (20%) (com inseticida) (80% Bt + 20% não Bt); 4) Cultivar Nuopal (sem inseticida) (100% Bt); 5) Cultivar Deltaopal (sem inseticida) (100% não Bt) e 6) Cultivar Nuopal centro (80%) e bordadura deltaopal (sem inseticida) (80% Bt + 20% não Bt). Realizaram-se amostragens semanais em 10 plantas por parcela de Alabama argillacea, Heliothis virescens e Spodoptera frugiperda. A ocorrência de A. argillacea e H. virescens foi menor nos tratamentos com a cultivar transgênica. Não ocorreram diferenças entre a cultivares quanto à ocorrência de S. frugiperda. O manejo das cultivares com inseticida obteve maior eficiência comparada ao tratamento sem inseticida no controle das lagartas.

ABSTRACT Among the options to control Alabama argillacea (Hübner, 1818) and Heliothis virescens (Fabricius, 1781) on cotton, insecticide spraying and biological control have been extensively used. The GM'Bt' cotton has been introduced as an extremely viable alternative, but it is yet not known how transgenic plants affect populations of organisms that are interrelated in an agroecosystem. For this reason, it is important to know how the spatial arrangement of pests and beneficial insect are affected, which may call for changes in the methods used for sampling these species. This study was conducted with the goal to investigate the pattern of spatial distribution of eggs of A. argillacea and H. virescens in DeltaOpalTM (non-Bt) and DP90BTMBt cotton cultivars. Data were collected during the agricultural year 2006/2007 in two areas of 5,000 m2, located in in the district of Nova América, Caarapó municipality. In each sampling area, comprising 100 plots of 50 m2, 15 evaluations were performed on two plants per plot. The sampling consisted in counting the eggs. The aggregation index (variance/mean ratio, Morisita index and exponent k of the negative binomial distribution) and chi-square fit of the observed and expected values to the theoretical frequency distribution (Poisson, Binomial and Negative Binomial Positive), showed that in both cultivars, the eggs of these species are distributed according to the aggregate distribution model, fitting the pattern of negative binomial distribution.
