Mature Larval Dispersal and Adult Emergence of the Economically Significant Pest, Scirtothrips aurantii Faure (Thysanoptera: Thripidae), in Commercial Citrus
Scirtothrips aurantii Faure (Thysanoptera: Thripidae) is a major pest of citrus fruit in subtropical southern Africa. Population monitoring is an important aspect of S. aurantii control, but additional information is required on its phenology. Dispersal of mature larvae onto the soil surface from the tree canopy, and emergence of adults, were assessed using dispersal/emergence (D/E) traps in an...
متن کاملMolecular identification key for pest species of Scirtothrips (Thysanoptera: Thripidae).
Effective plant quarantine and biological control initiatives require rapid and accurate identification of exotic and potentially invasive taxa that may cause high economic losses or environmental damage. The genus Scirtothrips Shull includes several species that are serious agricultural pests, and, because of their minute size and cryptic behavior, prone to undetected transport through interna...
متن کاملDevelopmental and reproductive biology of Scirtothrips perseae (Thysanoptera: Thripidae): a new avocado pest in California.
The developmental and reproductive biology of a new avocado pest, Scirtothrips perseae Nakahara, was determined in the laboratory at five constant temperatures, 15, 20, 25, 27.5 and 30 degrees C. At 20 degrees C, S. perseae exhibited greatest larval to adult survivorship (41%), and mated females produced a greater proportion of female offspring at this temperature when compared to 15, 25, 27.5 ...

متن کاملPredation behaviors of Franklinothrips orizabensis (Thysanoptera: Aeolothripidae) towards Scirtothrips perseae and Heliothrips haemorrhoidalis (Thysanoptera: Thripidae)
The foraging behaviors of predatory female Franklinothrips orizabensis Johansen towards Scirtothrips perseae Nakahara and Heliothrips haemorrhoidalis (Bouch e) in avocado leaf arenas were videotaped and analyzed. F. orizabensis encountered and attacked more second instar S. perseae with 80% ðn 1⁄4 113Þ attacks on this life stage being observed compared to 20% on first instars ðn 1⁄4 28Þ when eq...
