Abstract: |
With the aim to evaluate actual foliage loss due to potato leaf miner fly (PLMF), Liriomyza huidobrensis (Blanchard), survey sites were recognized from commercial potato pockets of Lalitpur, Kathmandu, Bhaktapur, Kavrepalanchwok, Sindhupalchwok and Makwanpur districts of Mid-Nepal in 2009. In total, 199 farmer's fields from 27 commercial potato pockets were visited and taken damage scores. The survey revealed that potato pockets of Lalitpur were the most prone area (89.3% foliage damage) to this pest followed by Kathmandu (82.6%), Bhaktapur (70%) and Kavrepalanchwok (46.5%). But damage level was comparatively lower in Sindhupalchwok (12.1%) and Makwanpur (27.9%). Damage level was found more in lower altitudes (790-1568 masl) than in higher altitudes (1560-2610 masl). Similarly, lower leaves were more damaged than the upper ones. So, altitude and plant age were two factors influencing damage by test insect. Since the pest is becoming severe and can withstand chemical sprays, it would be better to develop suitable IPM technique against this pest. Similarly, strict quarantine and awareness campaign against this insect pest are crucial to check its migration to virgin potato pockets. |
