Abstract
Performance of various trap crops in the management of Thrips tabaci L. in onion crop
Highlights
Thrips tabaci L. is a polyphagous and severe pest that cause considerable losses to onions throughout the world
Significant influence of the cultivation of trap crops was recorded on population of T. tabaci as comparatively more overall mean attraction of thrips was observed on marigold (11.61±0.40 thrips per plant), followed by fennel (8.51±0.30 thrips per plant), whereas, the minimum population was observed on carrot (5.77±0.25 thrips per plant)
Thrips tabaci was recorded since the transplanting of onions and the same showed a gradual rise till its maximum vegetative growth and declined towards the maturity of crop
Summary
Thrips tabaci L. is a polyphagous and severe pest that cause considerable losses to onions throughout the world. Thrips tabaci (Thysanoptera: Thripidae) is considered as one of the severe and damaging insect pests of onions throughout the world [6] Both adults and nymphs attack onion plant since its transplanting and could results in massive decline in the production [7]. Indiscriminate and uncaring use of these chemicals led to several serious problems for growers, their health and animals like toxic effects on non-target animal and insect species, resistance development in target pest due to the improper applications [13] Due to such problems, researchers and growers have developed and adopted other control methods like trap cropping to manage the populations of noxious pests including T. tabaci [14]. All the analysis was made using STATISTIX 8.1 computer software
