Estratégias de controle biológico de Urbanus acawoios (Williams, 1926) (Lepidoptera: Hesperiidae) e avaliação fitossanitária de Clitoria fairchildiana após ocorrência de pragas

Abstract

This work was conducted in distinct steps, involving different experimental, thus yielding two chapters. The first concerns the analysis of biological control tactics U. acawoios, which evaluates the feasibility of creating emerged parasitoids of caterpillars and pupae of U. acawoios; the caterpillars where emerged Cotesia sp. and pupae Brachymeria ovata and Diptera: Tachinidae. Which suggests the creation of the first two. And then in lab testing the efficiency of four entomopathogens U. acawoios caterpillars by a bioassay with six treatment solution diluted in 100 ml of distilled water and Tween Witness and the remaining 95ml solution plus 5 mL of concentrated Agent: with 3 species of entomopathogenic fungi (Beauveria bassiana, Metarhizium anisopliae, Cladosporium sp.) and 2 isolates of Bacillus thuringiensis isolated from Agribio ® and Dipel ®, with 4 replications. After 24h the bioassay facility, daily observations of caterpillars were held for 7 days to verify the same mortality. All treatments showed pathogenicity in U. acawoios caterpillars. The second chapter is about the evaluation of plant Clitoria fairchildiana analysis through an evaluation form, analyze the phytosanitary aspects of C. fairchildiana in Paracambi, where the species is recovered as an element of urban forestry and residential area in Seropédica . Also noted the presence of the psyllid Euphalerus clitoriae Burckhardt and Guajará, (2000) (Hemiptera: Psylloidea) and termites, and fungal species Fusarium sp. and Verticillium sp .. There was a greater presence of insects and fungi in Paracambi, but this was not statistically significant when compared with Seropédica. Thus, it is concluded that C. fairchildiana is able to restore after having suffered great injury U. acawoios caterpillars, thus not justifying their removal or replacement by other species.
