Antheraea mylitta

Antheraea mylitta, commonly referred to as the Indian tussar moth, belongs to the family Saturniidae (order Lepidoptera). While it is an economically significant species for silk production, its larvae can act as defoliators when their natural population density exceeds the carrying capacity of their host plants in specific forestry environments.

The host range of this insect includes various tree species, with a particular affinity for members of the Fagaceae family, such as Quercus (oak), as well as Terminalia and Shorea species. The larvae are voracious feeders, capable of consuming significant amounts of foliage within a short window of time.

The life cycle follows a complete metamorphosis: egg, larva, pupa, and adult. The larval stage is the primary period of impact. During their development through multiple instars, the caterpillars grow rapidly and require substantial nutrient intake. Following the larval phase, the insect spins a peduncled cocoon, which is a hallmark of this species, attached to the twigs of host trees.

The primary damage is caused by extensive leaf consumption, which leads to total or partial defoliation. This process deprives the tree of its primary photosynthetic organ, leading to physiological stress, reduced radial growth, and increased susceptibility to droughts or secondary pest infestations. In high-density outbreak areas, this can negatively impact the health of entire plantation stands.

Effective pest management for Antheraea mylitta relies on an integrated approach. Standard procedures include:

• Constant monitoring of egg masses during peak oviposition periods.
• Targeted application of biological insecticides such as Bacillus thuringiensis.
• Manual removal of cocoons to suppress future generations.
• Encouraging natural biological control agents, including various predatory insects and birds.
