          Abstract

          A biologia do percevejo predador Orius insidiosus (Say), utilizando como alimento, adultos de Caliothrips phaseoli (Hood), foi estudada em câmara climática com temperatura de 25±1°C, 70±10 % de UR e 12h de fotofase. O período de desenvolvimento ninfal foi de 10,2 dias, não apresentando diferença significativa para machos e fêmeas. A duração do estágio ninfal foi 1,9, 1,7, 1,4, 1,8 e 3,1 dias para o 1º, 2º, 3º, 4º e 5º ínstares, respectivamente. A viabilidade ninfal foi de 69,0%, sendo que a maior mortalidade ocorreu no 2º ínstar (16,0%). O. insidiosus predou 73,7 tripes durante todo o estágio ninfal. O consumo de presas pelas ninfas de O. insidiosus aumentou com os sucessivos instares: 6,1, 9,0, 11,4, 16,7 e 29,3 tripes do 1º ao 5º ínstares, respectivamente. Não houve diferença no tempo de busca para os diferentes ínstares do predador, sendo que durou em média 52 min., a captura da presa foi dificultada pela intensa reação de defesa apresentada pela mesma, que consistiu na sua maioria, em saltos e pequenas corridas. As fêmeas ovipositaram 77,8 ovos com viabilidade de 71,6% e com um período embrionário de 5,3 dias. A longevidade das fêmeas (21 dias) foi significativamente maior que a dos machos (12,4 dias). O consumo das fêmeas foi de 159,1 tripes e o dos machos de 60,7 tripes. Não foi observada diferença no tempo de busca para os diferentes instares de O. insidiosus. Os resultados indicam que adultos de C. phaseoli são presas adequadas ao desenvolvimento e reprodução do predador O. insidiosus.

          The biology of Orius insidiosus (Say) fed on thrips Caliothrips phaseoli (Hood) was studied in a climatic chamber at 25±1°C, 70±10% RH and 12h photophase. Nymphal developmental time (10.2 days) was the same for males and females. The durations of the nymphal instars were 1.9, 1.7, 1.4, 1.8 and 3.1 days for the 1st, 2nd, 3rd, 4th and 5th instars respectively. Nymphal survival was 69%, and the highest mortality occurred at the 2nd instar. O. insidiosus consumed 73.7 C. phaseoli throughout its nymphal stage. The amount of prey fed upon by O. insidiosus nymphs increased during the successive instars: 6.1, 9.0, 11.4, 16.7 and 29.3 thrips from the 1st to the 5th instar respectively. Females laid 77.8 eggs. Egg development in O. insidiosus took 5.3 days and only 71.6% of the eggs hatched. Female longevity was significantly higher (21 days) than that of males (12.4 days); consequently, females ate more thrips (159.1) than the males (60.7). The search time of O. insidiosus was the same for all instars. Thus, adults of C. phaseoli were proved suitable to the development and reproduction of the predator O. insidiosus.

            Bionomics of the Anthocoridae.

            J Lattin (1999)
            The family Anthocoridae (Hemiptera:Heteroptera) contains between 400 and 600 species distributed worldwide, chiefly on the continents but also on oceanic islands. They are small (1.4-4.5 mm) and common to a wide variety of habitats. Many are found in cryptic habitats such as galls, several widespread genera are surface feeders on small arthropods (Anthocoris, Orius, and Tetraphleps), and others can be found in ant nests and, especially, under bark. Wing polymorphism is common in this family, often associated with the cryptic habit. Most known species are predaceous, though some take plant food as well (e.g. Orius insidiosus, Orius pallidicornis). A few of these are believed to be entirely phytophagous (Paratriphleps laeviusculus). Their small size and often generalized feeding habits have resulted in about 30 introduced species, mostly accidental. A few have been introduced deliberately as biological control agents (Anthocoris spp., Montandoniola moraguesi, O. insidiosus, Orius tristicolor, and Tetraphleps spp.). Most nonindigenous species seem to have been distributed as a result of human activities, especially commerce. The predaceous habits of many Anthocoridae have attracted the attention of researchers who work in agroecosystems. Integrated pest management programs often include these predators, which has given us greater knowledge about these species than those found in natural ecosystems. Exciting discoveries about the attractiveness to these bugs of certain volatile plant and arthropod compounds are opening new areas of investigation into their chemical ecology. The reactions of these tiny predators will surely become better understood as a result.
