%X Effect of bean genotypes, insecticides, and natural products on the control of Bemisia tabaci (Gennadius) biotype B (Hemiptera: Aleyrodidae) and Caliothrips phaseoli (Hood) (Thysanoptera: Thripidae). The influence of bean genotypes associated with neem oil as insecticide was evaluated to control B. tabaci (Gennadius) biotype B and C. phaseoli (Hood) during the wet season sowing. The experimental design used was the randomized block arrangement in a 4x4x3 factorial scheme, represented by genotypes, neem oil and insecticides respectively, with three replications. The genotypes Carioca, IAC Harmonia, IAC Centauro and P谷rola were used. The evaluations were done at 14 and 42 days after seedling emergence, bycounting B. tabaci biotype B eggs and nymphs and C. phaseoli nymphs in the genotypes leaf. Conclusion: The B. tabaci biotype B eggs and nymphs number were smaller in IAC Centauro and higher in IAC Harmonia. The tested genotypes were similarly infested by C. phaseoli. IAC Centauro and IAC Harmonia genotypes associated with neem oil (highlighting the full dose 每 1%) provided lower number of whitefly eggs and thrips nymphs. Neem oil at the full dose alsoreduced whitefly nymph number. In the tested genotypes the insecticide provided reduction in the number of whitefly eggs and nymphs as well in the thrips nymphs, with increase in therecommend dose. Avaliou-se a influ那ncia de gen車tipos de feijoeiro associado 角 aplica  o de 車leo de nim e inseticida no controle de B. tabaci (Gennadius) bi車tipo B e C. phaseoli (Hood) na 谷poca de semeadura ※das 芍guas§. O delineamento experimental utilizados foi o de blocos casualizados dispostos em um esquema fatorial 4 x 3 x 3, representado por variedades, 車leo de nim e inseticidas, respectivamente, com tr那s repeti  es. Utilizaram-se os gen車tipos Carioca, IAC Harmonia, IAC Centauro e P谷rola. As avalia  es foram realizadas dos 14 aos 42 dias ap車s a emerg那ncia das plantas, contando-se o n迆mero de ovos e ninfas de B. tabaci bi車tipo B e ninfas de C. phaseoli nos fol赤olos dos gen車tipos. Concluiu-se: o n迆mero de ovos e ninfas de B. tabaci bi車tipo B foi menor em IAC Centauro e maior em IAC Harmonia. Osgen車tipos testados foram igualmente infestados por C. phaseoli. IAC Centauro e IAC Harmonia associado ao 車leo de nim e com destaque a dose cheia (1,0%), propiciaram menor n迆mero de ovos de mosca branca e de ninfas tripes, e o 迆ltimo deles atuou reduzindo o n迆mero de ninfas de mosca branca. Nos gen車tipos testados o inseticida proporcionou redu  o no n迆mero de ovos e ninfas de mosca branca e de ninfas de tripes, com incremento na dose recome
