Population ecology of onion leaf miner, Liriomyza hoidobrenssis (Blanchard) on garlic agro-ecosystem in Manipur, India


O Hemchandra, H Pravash Singh, M Bineshwar Singh

Liriomyza huidobrensis (Blanchard), the onion leaf miner or commonly known as pea leaf miner, is a highly polyphagous and cosmopolitan in distribution capable of inflicting severe damage to vegetable crops as well as various ornamental plants. Affected crops include field and glasshouse grown vegetable and flowers. Studies on population ecology of onion leaf miner on garlic agro-ecosystem were carried out for three cropping seasons (2017-18, 2018-19 and 2019-2020) in Manipur. Initially the pest density was very low i.e., 0.20 larvae/plant during first, second and third year, respectively. Their abundance gradually increased reaching the peak values of 16.15 larvae/plant, 28.05 larvae/plant and 20.45 larvae/plant with the infestation of 90 % (2017-2018), 70 % (2018-19) and 95 % (2019-2020) during March. The correlation coefficient showed higher temperature, lower relative humidity, lower total rainfall, longer duration of sunshine hours and higher wind speed seem to favour the pest population build up.
