The attack of the teak defoliator (Hyblaea puera) on Shisham (Dalbergia sissoo) and its environmental impacts

Abstract

In many areas, Dalbergia sissoo, sometimes called Shisham, is of great ecological and economic significance because of its sturdy wood and therapeutic qualities. However, a serious challenge to its sustainability is its vulnerability to infestation by the teak defoliator, Hyblaea puera. When H. puera larvae invade fake woods, they cause significant defoliation, which lowers photosynthetic activity and jeopardises tree health. The resulting loss of foliage impacts the natural balance of forest ecosystems in addition to reducing the grade of lumber.   Promising remedies are provided by integrated pest management strategies, which include sustainable forestry practices and biological control techniques. Furthermore, prompt action depends on early H. puera epidemic detection and surveillance. To protect Dalbergia sissoo woods from the damaging impacts of H. puera infestation, this article highlights the urgent necessity for a thorough study and the application of sustainable management approaches. Resolving these issues would protect the resilience of related socioeconomic systems that rely on this priceless tree species, in addition to maintaining the ecological integrity of Dalbergia sissoo ecosystems.
