CONTROL OF SCIRTOTHRIPS DORSALIS WITH FOLIAR INSECTICIDES, 2011

Evaluation of Entomopathogenic Fungi Against Chilli Thrips, Scirtothrips dorsalis

Commercial strains of entomopathogenic fungi were evaluated for control of chilli thrips, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae), an invasive pest of ornamental and vegetable plants in the Caribbean and southeastern United States. In laboratory assays, LC50 values against adult S. dorsalis were 5.1 × 10(4) CFU/mL for Beauveria bassiana GHA, with higher values 3.1 × 10(5) for Metar...

Strausbaugh, C. A., Wenninger, E. J., and Eujayl, I. A. 2014. Control of curly top in sugar beet with seed and foliar insecticides. Plant Dis. 98:10751080. Curly top in sugar beet is a serious problem that is caused by Beet curly top virus and other closely related species and transmitted by the beet leafhopper. In order to find a means of reducing curly top in sugar beet, 15 combinations of in...

Key for Identification of Adult Female of Scirtothrips dorsalis (Thysanoptera: Thripidae) Based on External Morphology

Thrips are minute insects and belong to the family thripidae of the order Thysanoptera. Thrips are less than two millimeters long, slender like and agile insects. Head of Scirtothrips dorsalis is pale in colour longer than broad, 217.5-237 μm long and 175-194 μm wide across the eyes. Eyes are redish in colour, 75-89 μm long and 63-70 μm wide at the middle and three occili are arranged triangula...

Development of a Ribosomal DNA ITS2 Marker for the Identification of the Thrips, Scirtothrips dorsalis

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...
