Biologia de dichelops melacanthus (heteroptera: pentatomidae) alimentado com diferentes dietas naturais

Abstract

The bed bug, Dichelops melacanthus, commonly known as belly-green bed bug has been cited in crops such as soybeans, maize (second crop) and wheat. To do so, it is necessary to know the biological parameters of the same, in order to enable its creation in the laboratory. In this way the objective of the study was to determine if natural diets based on seeds favor the development and reproduction of Dichelops melacanthus under controlled conditions. The work was carried out in the Entomology Laboratory of the Universidade Federal da Fronteira Sul, Campus Laranjeiras do Sul-PR, where different natural diets were tested: Peanut seeds, skinless sunflower, chickpeas, dry soybeans, The experimental design was a randomized complete block design with 7 treatments and 4 replicates (n = 4). The development of the third young phase until adulthood was evaluated, viability, adult weight, sex ratio and longevity. It is concluded that the natural diet of sunflower seed without skin, used from the third young phase, presented the best biological parameters, when compared to the other diets evaluated. In relation to fertility and fecundity, the diet with skinless sunflower seeds was efficient for the breeding of the pentatomids.
