WebLygus bugs damage fruit by puncturing individual seeds; this, in turn, stops development of the berry in the area surrounding the feeding site. Straw-colored seeds that are large and hollow are a good indication of lygus bug damage. Lygus bug damage is more of a problem in strawberry-growing areas where continuous fruit production occurs. Web18 iul. 2016 · The authors optimize the insecticidal activity of a Bacillus thuringiensis crystal protein and produce transgenic plants that are resistant to feeding damage by Lygusspecies. Lygus species of plant-feeding insects have emerged as economically important pests of cotton in the United States. These species are not controlled by …

WebA new phenomenon of proliferation and branching of cotton has spread through most of the cotton growing areas in Israel in the past few years. Aphids, green leafhoppers and mites were ruled out as possible causal agents of branching. Leaf damage and bud destruction, similar to those observed in the field, were obtained by prolonged feeding of a laboratory … Web1 dec. 2002 · Lygus lucorum Meyer-Dür, Adelphocoris fasciaticollis Reuter and Adelphocoris lineolatus (Goeze) (Hemiptera: Miridae) are important secondary insect pests in cotton fields in northern China.
