Heliothis Peltigera

AbstractHelicoverpa armigera (Hübner), H. assulta Guenée and Heliothis peltigera (Denis & Schiffermüller) were collected as mixed populations from safflower and the wild host Datura metel, from Patancheru, Andhra Pradesh, India, in 1992 and 1993, and their toxicological responses to insecticides determined. Both Helicoverpa armigera strains were highly resistant to cypermethrin, fenvalerate, endosulfan and quinalphos insecticides, based on resistance ratios relative to laboratory reared susceptible strains. There was no evidence of resistance development in H. assulta and Heliothis peltigera to the same chemicals. Light trap data collected from 1974 to 1987 showed that Helicoverpa armigera was at least 100 × more abundant than the other two species over most of the cropping season. Peak catches of H. assulta and Heliothis peltigera were confined to defined times in the season, corresponding with the flowering and fruiting periods of their respective host plants; August-October for Helicoverpa assulta and November-December for Heliothis peltigera. Helicoverpa armigera on the other hand, because of its high polyphagy on commercial and wild hosts, was abundant between August and April. Resistance has not developed in H. assulta and Heliothis peltigera in southern India, probably because of their restricted host range, limiting exposure to insecticides.

Damage Symptoms

In June 2015, infestations of sunflower crops by the bordered straw Heliothis peltigera (Lepidoptera: Noctuidae) were recorded in rural areas of the Regional Unit of Drama, N. Greece. Larval feeding-damage symptoms were observed on leaves and buds of sunflower plants, mostly at pre-flowering growth stages. Infestations were recorded in approximately 80% of the inspected sunflower fields, the infestation levels, however, were low (<5%) apparently resulting in no economic damage. The presence of H. peltigera has been reported in Southern and Central Europe, Canada, the Middle East and Africa, infesting several hosts. Infestations of sunflower crops have been reported in India, Pakistan and Sudan. To our knowledge, this is the first report of H. peltigera infestations on sunflower crops in Greece and possibly in Europe.

AbstractThe sexual behaviour of Heliothis peltigera (Denis & Schiffermüller) was studied in the laboratory. Calling activity was very low during the first five hours of scotophase and then increased sharply, particularly in six-to eight-day old females. Peak activity was observed, in all ages tested, between eight and nine hours into scotophase. Calling in six-day old females was significantly higher than in two-day old females but no significant differences were detected between four-to eight-day old females. Maximal amounts of pheromone were found in the pheromone glands of five-to eight-day old females in the second half of scotophase. Male activity was monitored in a wind tunnel. There was no response to pheromone lures during the first two days, then flying activity increased sharply and maintained its high level until the eighth day. Peak activity was observed between six and eight hours into scotophase. Mating activity was very low during the first five hours of scotophase and then increased sharply, with 61.8% of the observed pairs mating between six and eight hours into scotophase. The sexual behaviour of H. peltigera was very similar to the reported behaviour of the sympatric species Helicoverpa armigera (Hübner) indicating that the reproductive separation of the two species is not affected by temporal factors, but depends mainly on the species-specific pheromone blends.
