Abstract

GOMEZ, Victor A. et al. Biological aspects of Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae) reared in laboratory with different insects diets. Rev. Soc. Entomol. Argent. [online]. 2013, vol.72, n.1-2, pp.27-34. ISSN 0373-5680.

The study was done on the biological aspects of Piezodorus guildinii under laboratory conditions. The objective was to evaluate the development of nymphs in four natural diets and an artificial one. Diet N1 (Phaseolus vulgaris) lasted 35.09 days and diet N4 (Glycine max, Arachis hipogaea and Phaseolus vulgaris) lasted 23.60 days, with a lower mortality (20%). Artificial and natural diets with peanuts (A. hipogaea) did not allow the development of nymphs. In the adult phase three natural diets were evaluated. The entire cycle was larger in the N1 diet with 40.20 days and in the N4 diet with 28.80 days. The shortest preoviposition period was N6 diet with 11.13 days, (G. max, A. hipogaea, P. vulgaris and Ligustrum lucidum). The egg masses average from diets N4 and N6 were similar, 9.2 and 9.4 respectively. It was observed a higher viability in diet N6 with an average of 80%.
