Resumen de Influencia da radiaçao gama sobre adultos de "Tuta absoluta" (Meyrick)(Lepidoptera: Gelechiidae): nota
This work was carried out to verify the consumption of three lepidopterous eggs, Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Pyralidae), Sitotroga cerealella (Olivier, 1819) (Lepidoptera: Gelechiidae) and Anagasta kuehniella (Zeller, 1879) (Lepidoptera: Pyralidae) by Ceraeochrysa paraguaria (Navás, 1920) (Lepidoptera: Chrysopidae) and its effects on C. paraguaria development. The laboratory conditions were kept at 25 ± 2 ºC, 70 ± 10% RU and 14 hours of photofase. Larvae tests showed the following results: larval period was 14.40, 10.40 and 10.50 days and larvae viability 93.33%, 100.00% and 96.60% to larvae feeding on D. saccharalis, S. cerealella and A. kuehniella eggs, being the egg consumption 705,80, 972,10 and 934,24, respectively. The pupal period an pupae viability were 11.90, 13.13 and 12.63 days, and 90.00%, 90.00% and 86.67%, respectively for A. kuehniella, S. cerealella and D. saccharalis. C. paraguaria have had excellent development and viability under different food conditions, showing a great viability for mass rearing programs.
