MATHIAS HOLTZ, Anderson et al. IS THE ASOCIATION OF PODISUS NIGRISPINUS AND SPECIES OF THE TRICHOGRAMA POSIBLE IN PROGRAMS OF BIOLOGICAL CONTROL IN FORESTS?. Idesia [online]. 2006, vol.24, n.2, pp.85-88. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292006000200010.

Alternatives for the control of pests in forest sectors have been searched. A possibility is the use of the biological control with predators and parasitoids. The objective of this work was to evaluate the parasitism of different Trichogramma species in P. nigrispinus egges. For each treatment fifteen P. nigrispinus egges, of the same posture, with one day of age, were agglutinated in rectangles of celestial blue cardboard. They were exposed to the parasitism of 5 female Trichogramma species for 24 hours. Besides those that underwent the tests, P. nigrispinus egges that were not submitted to the parasitoid presence were used. There were parasitoid adults’ that originated from of those eggs born and the viability of all of the five species used was not affected. The predator P. nigrispinus and the parasitoid Trichogramma can be used in programs of biological control.
