Resumo: | Several psiculture stations that deal with fingerlings or ornamental fishes rearing have presented some problems with larvae preying, post-larvae and fingerlings by Odonata Order insect nymphs. Thus, the aim of this work was to survey the Odonata species present in fish-raising tanks in two towns of the Midwest region of Minas Gerais, and also to evaluate the effect of Bacillus thuringiensis var. Barjac israelensis on Pantala flavescens nymphs (Fabricius, 1798) (Odonata: Libellulidae). Fortnightly collections were performed over a three month period. The adult insects were captured with entomological nets and the nymphs with fine mesh sieves, coupled to wooden handles. The captured nymphs were taken to the laboratory where they were individualized in 2L plastic foam boxes and sealed in its upper extremity with tulle. Soon after the adults emergence, they were killed, packed into envelopes and sent to be identified. The laboratory experiments were conducted in an acclimatized room at 25 ± 2°C, RH of 70 ± 10% and 12-hour photophase. Second instar P. flavescens nymphs were packed individually into plastic foam boxes containing 500mL of chlorine free water each one. When they were in the third, fifth and seventh instars, they were treated with B. thuringiensis var. israelensis through the microbial product Vectobac® in granulate formulation. The product was directly applied to the rearing container water at the concentration denoted for the control of culicidae larvae, two superior concentrations, two inferior and also another one, where the product was not applied. The evaluations were done at 24, 48 and 72 hours after the product application, recording the dead insects number in each treatment. In both experiments, the nymphs were fed with Culicidae larvae and new-born fishes of the species Poecilia cf. vivipara Schneider, 1801. The following species were identified: Ischnura fluvialis Selys, 1876; Aphylla theodorina (Navas, 1933); Brachymesia furcata (Hagen, 1861); Erythrodiplax fusca (Rambur, 1842); Miathyria marcella (Selys, 1857); Micrathyria almeidai Santos, 1945; Micrathyria hesperis Ris, 1911; Orthemis discolor (Burmeister, 1839); Perithemis mooma Kirby, 1889 and P. flavescens. There were no significant microbial product effects on the studied species |

There were no significant microbial product effects on the studied speciesVárias estações de piscicultura que trabalham com a produção de alevinos ou peixes ornamentais têm apresentado problemas relacionados à predação de larvas, pós-larvas e alevinos por ninfas de insetos da Ordem Odonata. Dessa forma, objetivou-se fazer um levantamento de espécies de odonatos presentes em tanques de criação de peixes em dois municípios da região centro-oeste de Minas Gerais, assim como avaliar o efeito de Bacillus thuringiensis var. israelensis de Barjac sobre ninfas de Pantala flavescens (Fabricius, 1798) (Odonata: Libellulidae). Durante um período de três meses, foram realizadas coletas quinzenais, sendo os insetos adultos capturados com o auxílio de redes entomológicas e as ninfas, através de peneiras de malha fina, acopladas a cabos de madeira. As ninfas capturadas foram levadas para o laboratório onde foram individualizadas em caixas de isopor com capacidade para 2L, vedadas em sua extremidade superior com filó. Logo após a emergência dos adultos, esses foram mortos, acondicionados em envelopes e enviados para serem identificados. Os experimentos laboratoriais foram conduzidos em sala climatizada à 25 ± 2°C, UR de 70 ± 10% e fotofase de 12 horas. Ninfas de segundo ínstar de P. flavescens foram individualmente acondicionadas em caixas de isopor contendo cada uma 500mL de água livre de cloro e, estando essas no terceiro, quinto e sétimo ínstares, foram tratadas com B. thuringiensis var. israelensis, através do produto microbiano Vectobac®, em formulação granulada. O produto foi aplicado diretamente na água do recipiente de criação, em concentração indicada para o controle de larvas de culicídeos, duas concentrações superiores e duas inferiores a essa, além da testemunha, na qual não se aplicou o produto. As avaliações foram realizadas a 24, 48 e 72 horas após a aplicação do produto, registrando-se o número de insetos mortos em cada tratamento. Em ambos os experimentos, as ninfas foram alimentadas com larvas de mosquito da Família Culicidae e peixes recém-nascidos da espécie Poecilia cf. vivípara (Schneider, 1801). Foram identificadas as seguintes espécies: Ischnura fluvialis Selys, 1876; Aphylla theodorina (Navas, 1933); Brachymesia furcata (Hagen, 1861); Erythrodiplax fusca (Rambur, 1842); Miathyria marcella (Selys, 1857); Micrathyria almeidai Santos, 1945; Micrathyria hesperis Ris, 1911; Orthemis discolor (Burmeister, 1839); Perithemis mooma Kirby, 1889 e P. flavescens.
