“…This observation corroborates of De Cock et al (1996), who reported a high toxicity of imidacloprid insecticide to fifth instar nymphs and adults of P. maculiventris by ingestion as compared to topical exposure. De Clercq et al (1995) found higher mortality caused by diflubenzuron in the drinking water to P. maculiventris than pyriproxyfen; however diflubenzuron was not active by residual and direct contacts.…”

“…Nymphs of P. maculiventris were more susceptible after topical exposure to imidacloprid than adults (De Cock et al, 1996) what was also found for P. nigrispinus after topical exposure to gamma-cyhalothrin. This may explain the different cuticular penetration rate of insecticides topically applied to P. maculiventris (Yu, 1988).…”

“…Para tiametoxam foi constatada predação, embora os predadores se apresentassem em estado moribundo, com falta de coordenação e sem capacidade de locomoção durante a avaliação, considerando-se 100% de mortalidade neste tratamento. Toxicidade semelhante foi observada por De Cock et al (1996) para P. maculiventris tratado residualmente com o neonicotinóide imidaclopride. Por outro lado, o metiocarbe causou 100% de mortalidade dos predadores e não foi observada predação.…”

“…De Cock et al (1996) determinaram CL 50 de 86,7 e 179,3 mg de i.a./l, por contato residual e tópico do diafentiurom, respectivamente, para adultos do percevejo predador P. maculiventris. Esses valores, embora considerem 50% de mortalidade da população, são 30,7 e 14,8 vezes menores que a concentração recomendada para o controle de pragas do algodoeiro e usada neste estudo (400 g i.a./ha em 150L/ha; Tabela 1.…”
