Abstract: Avaliou-se o efeito do regulador de crescimento de insetos lufenuron (Match CE) sobre a fecundidade dos adultos e a viabilidade de ovos de Diabrotica speciosa (Germar) (Coleoptera: Chrysomelidae), em laboratório. Adultos recém-emergidos da criação foram separados por sexo, colocando-se um casal por gaiola de acrílico transparente. Quinze casais foram alimentados com folhas de feijão (Phaseolus vulgaris L.) tratadas com lufenuron, durante 13 dias após o acasalamento. Após esse período, os insetos foram alimenta… Show more

“…Negative effects on fecundity and fertility of some insect species caused by chemical compounds were also found by other authors. Ávila and Nakano (1999) evaluate the toxic effects of the growth regulator lufenurom (0.33 g a.i ha) on adult fecundity and egg viability of Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae) in the laboratory. The authors say the low number of eggs (177.5) as well as their low viability (19.8%) obtained from couples who have ingested the insecticide can be explained by trans ovarian transmission, affecting embryonic development and preventing larvae hatching.…”

“…Efeito prolongado com 100% de inviabilidade de ovos da joaninha predadora Cryptolaemus montrouzieri Mulsant foi constato por Hatting & Tate (1995) após 20 dias da pulverização das plantas de citros com triflumurom e piriproxyfem. Ávila & Nakano (1999) também verificaram acentuado efeito do lufenurom sobre a produção de descendentes por fêmeas de Diabrotica speciosa (Germar) após serem alimentadas com folhas de feijoeiro tratadas com 0,033% de lufenurom. De acordo com Cassana et al (1999), fêmeas de Ceratitis capitata (Wied.)…”

“…Por possuírem ação predominante na fase jovem e por ingestão, os IRC têm sido uma opção para o controle de larvas desfolhadoras em geral. No entanto, esses produtos têm apresentado efeito na fecundidade e na viabilidade de ovos em insetos de diferentes ordens (Grosscurt 1978, Smagghe & Degheele 1994, Ávila & Nakano 1999.…”

“…In this sense, it is possible that effect over the spermatogenesis or oogenesis in insect occurred, although study shows that the effect of lufenuron on Diabrotica speciosa females wasn´t necessarily sterilizing [28].…”
