Damage Analysis of Chillie Thrips, Scirtothrips dorsalis Hood(Thysanoptera: Thripidae) on Grape.

An Overview of Chilli Thrips, Scirtothrips dorsalis (Thysanoptera: Thripidae) Biology, Distribution and Management

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...

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...

Estimating Bacterial Diversity in Scirtothrips Dorsalis (thysanoptera: Thripidae) via next Generation Sequencing.

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...
