• Some methods of biological pest control have proved useful against lygus bugs.
• It is being studied for use against lygus bug on cotton and thrips in vegetables.
• Tarnished plant bugs ( Lygus rugulipennis ) are true bugs, members of the order Hemiptera, related to squash bugs and stink bugs.
• The lygus injects a poisonous substance into the seeds on the skin of strawberries, causing the seeds to die and making for misshapen berries.
• Agricultural pests like " Lygus hesperus " damage cotton and other crops because they secrete PGs in their saliva that digest plant tissue.
• This species is extremely similar to " Lygus pratensis ", although on average it is slightly smaller, with a shorter membrane.
• This species is very similar to " Lygus wagneri ", but usually it is slightly larger, has longer membrane and a more densely pubescent corium.
• "Schinia lynx " ( Lynx Flower Moth ) caterpillars feed on the flowers and seeds of Annual Fleabane and other fleabanes, and " Lygus lineolaris " ( Tarnished Plant Bug ) sucks the plant juices.
• So-called trap crops _ flowers, alfalfa _ planted alongside cash crops attract beneficial insects and simultaneously take care of such nasty critters as the lygus bug, a small insect that winters in the hills and comes down to the valley in spring.
• However, given a flavor choice of strawberry or alfalfa, the lygus will go for alfalfa every time, leaving the berries unmolested and proving that organic methods not only make good sense on ecological grounds but are also cost-effective, Jones says.
• Most of the pests found were western flower thrips ( " Frankliniella occidentalis " ), " Lygus " species such as the tarnished plant bug ( " L . lineolaris " ), and various spider mites from the family Tetranychidae.
• For example, wasps of the genus " Peristenus " are parasitoids of lygus bugs; an adult wasp will inject an egg into a lygus nymph, and once the egg hatches the wasp's larva will consume the nymph from the inside out.

• Specific pest species that have been successfully controlled by pyrethrum include : potato, beet, grape, and six-spotted leafhopper, cabbage looper, celery leaf tier, Say s stink bug, twelve-spotted cucumber beetle, lygus bugs on peaches, grape and flower thrips, and cranberry fruitworm.
• A 2011 study based on a survey of 1, 000 randomly selected farm households in five provinces in China found that the reduction in pesticide use in Bt cotton cultivars was significantly lower than that reported in research elsewhere : The finding was consistent with a hypothesis that more pesticide sprayings are needed over time to control emerging secondary pests, such as aphids, spider mites, and lygus bugs.
• Other significant global pests of cotton include the pink bollworm, " Pectinophora gossypiella "; the chili thrips, " Scirtothrips dorsalis "; the cotton seed bug, " Oxycarenus hyalinipennis "; the tarnish plant bug, " Lygus lineolaris "; and the fall armyworm, " Spodoptera frugiperda ", " Xanthomonas citri subsp . malvacearum ".
