The fall armyworm is one of the most important crop pests worldwide, and the parasitoid wasp T. remus is considered a potential control agent. Through laboratory evaluation, it was found that the selected isoline maintained good flight capacity and parasitism efficiency, with optimal flight performance at specific temperature and humidity levels.
The widely distributed, polyphagous fall armyworm, Spodoptera frugiperda (J.E. Smith, 1797), is one of the most important crop pests worldwide. The egg-parasitoid wasp, Telenomus remus Nixon, 1937, is frequently described as a possible control agent for S. frugiperda. We selected an isoline of T. remus and evaluated its parasitism potential (for 24 h) in S. frugiperda eggs, in laboratory conditions, and also its ability to fly at different temperatures and relative humidity levels, aiming to provide basic information about this isoline. The selected isoline maintained good flight capacity without affecting its parasitism efficiency or developing inefficient haplotypes for biological-control programs, compared across generations to a regularline laboratory-reared for more than 60 generations. The flight capacity of the isoline was best at 25-30 & DEG;C and relative humidity 70-90%.
