Estudou-se a biologia de Dysdercus peruvianus Guérin-Méneville, percevejo manchador do algodoeiro, em sete temperaturas (18, 20, 22, 25, 28, 30 e 32ºC), visando a determinação das suas exigências térmicas para programas de manejo de pragas do algodoeiro. O desenvolvimento embrionário de D. peruvianus não se completou a 32ºC. Nas demais temperaturas, embora tenha ocorrido uma variação do período ovo-adulto de 25,1 dias (30ºC) a 68,5 dias (18ºC), os insetos apresentaram sempre cinco ínstares. A maior mortalidade na fase ninfal foi registrada nas temperaturas mais altas, evidenciando a adaptação de D. peruvianus às baixas temperaturas, embora a mortalidade em todas as temperaturas tenha sido elevada nos dois primeiros ínstares. O limiar térmico inferior de desenvolvimento de D. peruvianus (temperatura base) foi de 12,86ºC para o ciclo total, com exigências térmicas de 419,66 graus dias. O limiar inferior de desenvolvimento foi de 10,46ºC para a fase de ovo, sendo crescente do 1º ao 4º ínstar ninfal (respectivamente, 9,98, 12,58, 13,73 e 13,93ºC), diminuindo no último ínstar (11,91ºC).

ABSTRACTDespite the great morphological diversity of insects, there is a regularity in their digestive functions, which is apparently related to their physiology. In the present work we report the de novo midgut transcriptomes of four non-model insects from four distinct orders: Spodoptera frugiperda (Lepidoptera), Musca domestica (Diptera), Tenebrio molitor (Coleoptera) and Dysdercus peruvianus (Hemiptera). We employed a computational strategy to merge assemblies obtained with two different algorithms, which substantially increased the quality of the final transcriptomes. Unigenes were annotated and analyzed using the eggNOG database, which allowed us to assign some level of functional and evolutionary information to 79.7% to 93.1% of the transcriptomes. We found interesting transcriptional patterns, such as: i) the intense use of lysozymes in digestive functions of M. domestica larvae, which are streamlined and adapted to feed on bacteria; ii) the up-regulation of orthologous UDP-glycosyl transferase and cytochrome P450 genes in the whole midguts different species, supporting the presence of an ancient defense frontline to counter xenobiotics; iii) evidence supporting roles for juvenile hormone binding proteins in the midgut physiology, probably as a way to activate genes that help fight anti-nutritional substances (e.g. protease inhibitors). The results presented here shed light on the digestive and structural properties of the digestive systems of these distantly related species. Furthermore, the produced datasets will also be useful for scientists studying these insects.

Studies were carried out to evaluate the insecticidal activity of Pilocarpus spicatus Saint-Hilaire (Rutaceae) essential oil (EO) on the development of the Hemiptera Dysdercus peruvianus (Guérin-Méneville, 1831) and Oncopeltus fasciatus (Dallas, 1852). Gas Chromatography/Mass spectrometry analysis revealed a chemical composition with sabinene (32.27%) and sylvestrene (27.26%) as major constituents. Topical and continuous treatment with the pure EO induced 100% of mortality while serial dilutions of the EO induced different levels of lethality in a dose response manner. Median lethal dose (LD50) and lethal dose 90% (LD90) were determined. Malformations in insects and permanent or supernumerary nymphs were often observed after treatments, and the use of scanning electron microscopy allowed the analysis of morphological changes. The different biological effects of P. spicatus EO point out its potential as a rich source of bioactive molecules to be used as an alternative control method against agricultural pest insects.
