Abstract:
The exclusive food source for silkworm (Bombyx mori L.) is mulberry leaf and productivity of quality mulberry leaves is crucial for successful sericulture. However, mulberry plants are susceptible to various pests, among which the mulberry pyralid, Glyphodes pyloalis Walker (Lepidoptera: Pyralidae) poses a significant threat to mulberry particularly in the temperate region of Jammu & Kashmir, India. The larvae of this pest exhibit voracious feeding behaviour towards mulberry leaf which compromises its nutritional quality and synchronization in the lifecycle of the pest and silkworm rearing ultimately impacts the growth, development and cocoon production of silkworms during the summer and autumn seasons. The present study assessed the impact of Glyphodes pyloalis Walker infestation on major nutrients and biochemical compounds of eight mulberry genotypes viz., Goshoerami, KNG, Koksu-21, Koksu-20, Ichinose, Enshutakasuke, Kairiyoroso and Kanva-2. Significant reductions were recorded in nitrogen, phosphorus, potassium, total protein, total carbohydrate and chlorophyll content in infested leaves when compared to healthy leaves. Additionally, a rise in total phenol content was observed in the infested leaves. These results highlight the importance of managing G. pyloalis in order to maintain the leaf quality which is essential for the productivity of the sericulture industry.
