Adult chilli thrips have pale bodies with dark wings and typically are less than 2 mm in length. Crop yields were often significantly greater when oxamyl followed fumigation, as compared to fumigation only, which could be due to a reduction in root-knot nematode damage (and in the case of eggplant also reduced foliar damage by insects), and/or to a carbamate growth stimulant response. It is a major pest of many host plants, including vegetable, ornamental and fruit crops. Symptoms and host range were similar to those described for infection by Cucumber leaf spot virus (CLSV) (1). We also provide student loans to assist in the education of our members. Based on the serological relationships of NPs, tospoviruses are classified into three serogroups and four distinct serotypes. Chilli thrips can cause serious damage to plants, as they have piercing mouthparts that extract the contents of epidermal cells, leading to necrosis of plant tissue.
