Abstract

Populus spp. belongs to the deciduous flowering plants in the family Salicaceae, primarily located in the Northern Hemisphere, including Trans-Himalayan, cold arid desert Ladakh. In Ladakh, it is predominantly cultivated in irrigated land patches along the riverbanks. This plant holds significant economic value as its wood is extensively used in furniture-making and house constructions. Recently, a highly successful pest, identified as Pheosia albivertex (Hampson 1983), was observed infesting the Populus plantations, marking a new record of insect infestation. The pest causes complete defoliation, particularly during midsummer, which is the prime foliage period. The initial sighting of this insect occurred in Dyanguchay village, Suru-valley, Kargil district of the union territory of Ladakh. However, during a thorough three-year-and-five-month investigation from April 2019 to August 2022, it was found spreading to neighbouring areas. Consequently, without timely control measures, it poses a significant threat to the popular plantation in Ladakh and other adjoining areas.

首次报告印度拉达克的入侵害虫 Pheosia albivertex（Hampson，1983 年）（鳞翅目：啄木鸟科）在白杨（莎草科）上的分布情况

杨属植物属于莎草科落叶开花植物，主要分布在北半球，包括跨喜马拉雅山脉的寒冷干旱沙漠拉达克。在拉达克，它主要种植在河岸灌溉地块。这种植物具有重要的经济价值，因为它的木材被广泛用于家具制造和房屋建筑。最近，人们在杨树种植园中发现了一种非常成功的害虫，被确认为 Pheosia albivertex（汉普森，1983 年），这是一种新的虫害记录。这种害虫会造成完全落叶，尤其是在仲夏的黄金落叶期。最初发现这种昆虫的地方是拉达克联邦领地卡吉尔地区苏鲁谷的 Dyanguchay 村。然而，在 2019 年 4 月至 2022 年 8 月为期三年零五个月的彻底调查中，发现这种昆虫蔓延到了邻近地区。因此，如果不及时采取控制措施，它将对拉达克和其他毗邻地区的流行种植构成重大威胁。
