1. Understanding Jassids: Biology and Behavior

To effectively control jassids, it’s crucial to understand their biology and behavior. Jassids, also known as leafhoppers, belong to the family Cicadellidae. The species that commonly affects tea plantations is Empoasca flavescens, often referred to as the tea jassid.

Life Cycle of Jassids

Eggs: Female jassids lay eggs inside the leaf tissue or tender stems.
Nymphs: The jassid nymph stage consists of five instars, each lasting about a week.
Adults: Mature jassids are small, green, wedge-shaped insects about 3-4 mm long.

The entire life cycle from egg to adult typically takes 3-4 weeks, depending on environmental conditions. Understanding this cycle is crucial for timing control measures effectively.

Behavior and Feeding Habits

Jassids are sap-sucking insects that feed on the undersides of tea leaves. Both adults and nymphs extract plant sap using their piercing-sucking mouthparts. This feeding activity leads to various symptoms and damage to the tea plants.

2. The Impact of Jassids on Tea Plantations

The presence of jassids in tea plantations can have severe consequences for both the quantity and quality of tea production. Let’s examine the various ways in which these pests affect tea plants:
