Resumo: The behavior of Aphidius sp. and B. brassicae populations on cabbage cultivars Kobayashi, Roxo, Chato de Quintal, Coração de Boi and Matsukase were studied in natural field conditions. Monthly samples were collected from August to December 1995. Leaf discs measuring 6.1cm2 were taken from sites showing higher aphid concentration from each most infected leaf. The percentage of parasitized insects was determined by the number of mummified aphids among the total on each leaf disc. Although Roxo and Kobayashi cultivars showed the highest aphid infestation, they were the least parasitized by Aphidius sp., with 23.3% and 25% parasitism, respectively. Coração de Boi and Chato de Quintal cultivars were the least infested by the aphid, but showed the highest parasitoid populations, as 51.7% and 67.5% respectively. The lower aphid and parasitoid populations were observed on Matsukase cultivar. Chato de Quintal, Coração de Boi and Matsukase cultivars presented a high aphid and parasitoid populations in August, which decrease in September and December and rose in October and November. On Kobayashi and Roxo cultivars both populations increased until November and decreased in December. Generally, higher B. brassicae and Aphidius sp. populations were found during August, October and November. The average parasitism in all cultivars was 36%. The highest parasitism level was 55.8, observed in August. KEY-WORDS: Aphidius; Brevicoryne brassicae; comportamento; parasitism; behavior.

Estudou-se o comportamento das populações de Aphidius sp. e B. brassicae nas cultivares de repolho ‘kobayashi’, ‘roxo’, ‘chato de quintal’, ‘coração de boi’ e ‘matsukase' em infestações naturais no campo. As amostragens foram mensais, de agosto a dezembro de 1995, coletando-se de cada folha mais infestada um disco foliar de 6,1 cm2 de área, no ponto de maior concentração de pulgões. O percentual de parasitismo foi determinado contando-se o número de pulgões mumificados em relação ao total de cada disco foliar. As cultivares ‘roxo’ e ‘kobayashi’ foram as mais infestadas pelo pulgão, no entanto apresentaram o menor índice de parasitismo por Aphidius sp., com 23,3% e 25% respectivamente, enquanto a ‘coração de boi’ e ‘chato de quintal’ foram as menos infestadas pelo pulgão, mas apresentaram as maiores populações do parasitóide, com 51,7 e 67,5% de parasitismo. As menores populações do pulgão e do parasitóide foram observadas na cultivar ‘matsukase’. As cultivares ‘matsukase’, ‘chato de quintal’ e ‘coração de boi’ apresentaram altas populações do pulgão e do parasitóide nos meses de agosto, outubro e novembro. Nas cultivares ‘kobayashi’ e ‘roxo’ houve um crescimento de ambas as populações até novembro. No geral as maiores populações de B. brassicae e do Aphidius sp. foram observadas nos meses de agosto, outubro e novembro. O parasitismo em B. brassicae observado em todas as cultivares, foi de 36,3% e o maior índice ,55,8%, foi observado no mês de agosto.
