The Scirtothrips perseae species-group (Thysanoptera), with one new species from avocado, Persea americana.
نویسندگان
چکیده
Following recent molecular studies on avocado thrips, a new species is described from Costa Rica, Ecuador, and Colombia from the young leaves of avocado, Persea americana. Scirtothrips hansoni sp.n. is closely related to the Californian pest, S. perseae, and also to S. astrictus from Costa Rica that remains known from a single female. An illustrated key to these three species is provided.

Foreign exploration for Scirtothrips perseae Nakahara (Thysanoptera: Thripidae) and associated natural enemies on avocado (Persea americana Miller)
Scirtothrips perseae Nakahara was discovered attacking avocados in California, USA, in 1996. Host plant surveys in California indicated that S. perseae has a highly restricted host range with larvae being found only on avocados, while adults were collected from 11 different plant species. As part of a management program for this pest, a ‘‘classical’’ biological control program was initiated and...
متن کاملAvocado thrips: New challenge for growers
Avocado thrips arrived in California in 1996. Since then, we have made substantial progress in our understanding of this pest. We now know the area of origin of the avocado thrips and have compiled an inventory of other potential pest thrips species on avocados in Mexico and Central America. Trials have helped us to identify several selective insecticides for use in treating avocado thrips in o...

Results of analyses of molecular sequence (COI, 28S-D2) and morphology (21 character states) data, both alone and combined, were used to determine relationships between 18 species of Scirtothrips (Thysanoptera: Thripidae, Thripinae). Two species of Neohydatothrips from Panama were used as the outgroup. Five major pest Scirtothrips were included in these analyses: S. aurantii, S. citri, S. dorsa...
متن کاملThe economic impact of Scirtothrips perseae Nakahara (Thysanoptera: Thripidae) on California avocado production
In 1996, Scirtothrips perseae Nakahara (Thysanoptera: Thripidae) invaded California avocado orchards and moved pest management practices that relied almost exclusively on biological control to strategies dependent on insecticides to maintain thrips densities below economically damaging levels. By 1998, average losses due to thrips feeding damage in untreated infested groves reduced industry rev...
متن کاملComparison of Scirtothrips Perseae (thysanoptera: Thripidae) Infestation Levels on Avocado Fruit and Leaves
Avocado fruit can be severely damaged by Scirtothrips perseae (Thysanoptera: Thripidae) in southern California. Scirtothrips perseae is found on leaves and fruit, but its prevalence on one versus the other substrate has not been documented. In this study, the occurrence and infestation levels of S. perseae on avocado leaves and fruit during late spring and summer were compared at three sites in...
