The thrips Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an invasive pest that poses a significant economical threat to U.S. agriculture and trade. In this study, DNA sequence data and polymerase chain reaction (PCR) were utilized to develop a molecular diagnostic marker for S. dorsalis. The DNA sequence variation from the internal transcribed spacer 2 (ITS2) region of nuclear ribosom...
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...

The last 2 decades have produced a better understanding of insect-microbial associations and yielded some important opportunities for insect control. However, most of our knowledge comes from model systems. Thrips (Thysanoptera: Thripidae) have been understudied despite their global importance as invasive species, plant pests and disease vectors. Using a culture and primer independent next-gene...
A field experiment was conducted during the summer 2019 to manage significant pests and diseases of groundnut. Four farming methods were evaluated against Aphis craccivora, Scirtothrips dorsalis, Spodoptera litura andearly leaf spot (Cercospora arachidicola). Among different methods, Natural (NF) (neemastra @ 625 lit/ha) significantly reduced craccivora (3.92 aphids /plant) dorsalis (11.80%) at...
