Resumen

ZACHRISSON, Bruno; POLANCO, Pamela  y  MARTINEZ, Onesio. Biological and reproductive performance of Oebalus insularis Stal (Hemiptera: Pentatomidae) on different host plants. Rev. Protección Veg. [online]. 2014, vol.29, n.2, pp.77-81. ISSN 1010-2752.

Obtaining eggs of Oebalus insularis Stal., for the multiplication of Telenomus podisi Ashmead depends on the quality of the food provided by diverse host plants. Therefore, the biological and reproductive performance of O. insularis on Oryza sativa L. and Echinochloa colona (L.) was determined at 28+2°C, 80 + 5% of relative humidity and 12 hours photophase. The duration of the period of nymph eclosion until the emergence of the adult of O. insularis varied between 20,9 and 21,2 days, for O. sativa and E. colona, respectively. The longevity of the female and male of O. insularis was statistically similar on both host plants. The female longevity was higher than that shown by the male, varying between 15 and 12 days, respectively. The O. insularis female fed with E. colona presented a high number of eggs per batch, total number of eggs per female and the eclosion rate of nymphs was higher. The biological and reproductive parameters of this insect confirmed their adaptation to the alternative host E. colona, optimizing the production of eggs subjected to T. podisi parasitism.
