Evaluating the Effectiveness of Different Traps for Monitoring the Invasive Leaf Miner, Liriomyza huidobrensis on Potato Crop (Solanum tuberosum) in India

Potatoes (Solanum tuberosum L.; Solanaceae) are individual of the world’s four important food crops. However, it is currently endangered by the obtrusive, most devastating leaf miner, Liriomyza huidobrensis (Blanchard, 1926) (Diptera: Agromyzidae). Potato plays a important role in the Indian frugality. During the year 2020-21, the outbreak concerning this pest was noticed in the potato increasing regions of the Nilgiris district. During the period 2021, two experiments were carried out at two various locations of Nilgiris district in consideration of monitor the pest occurrence for timely application of administration practices. In this study, the effectiveness of various kinds of traps viz., embarrassing traps (yellow, white, sad) and bottle traps accompanying casein and protein hydrolysate were tested. The verdicts demonstrate that of the differing traps tested for their efficacy in fascinating the leaf miner, L. huidobrensis, the yellow difficult trap was more effective in attracting adult leaf digger flies, accompanying mean trap catches of 40.49 and 36.64 adult flies/ 10 cm2 regions at Kotagiri and Ooty, respectively. The peak population of leaf miners was noticed in the last week of April (45.67 adult flees/ 10 cm2 areas) in Ooty and the third temporal length of event or entity’s existence of June (52.33 adult flies/ 10 cm2 extents) in Kotagiri. The correlation investigation raise that the trap catches were significantly definitely correlated accompanying maximum temperature, diurnal alternative (DV), and growing era degrees (GDD). Multiple regression equating was also grown, where the abiotic factors donated 46.1% and 65.5% to the Liriomyza leaf miner populace fluctuation in the vegetable ecosystem. Yellow sticky trap maybe used as an adept tool to monitor the incidence of L. huidobrensis community. The data acquired may also be secondhand in projecting their future community by adopting pest management models.
