Striped-neck cricket

Systematic position: The Metioche vittaticollis belongs to the order Orthoptera, family Gryllidae. This insect is widely recognized in the agricultural landscapes of Asia, where it is classified as a pest of significant concern for cereal production systems.

Host plants: The primary host for this species is rice (Oryza sativa). However, because of its opportunistic feeding habits, it can also be found on various grasses and associated weeds, which allows the population to persist even when rice is not actively available in the fields.

Biology and life cycle: The life cycle involves incomplete metamorphosis. Eggs are usually laid in stems or moist substrate. Nymphs pass through several instars, feeding actively. Their development is highly influenced by climatic conditions, with high humidity and warmth facilitating faster growth rates and increased reproductive success throughout the season.

Damage and economic significance: The economic damage is primarily caused by both adults and nymphs feeding on the reproductive parts of the rice plant. By consuming pollen and the contents of developing grains, they interfere with the fertilization process, which directly results in reduced grain yield and lower-quality yields that do not meet market standards.

Control measures: Management of this pest requires a strategic approach.

• Removing alternate host plants and weeds in and around the fields.
• Implementation of synchronized planting dates to limit the availability of susceptible plant stages.
• Applying targeted insecticides only when scouting confirms high infestation levels.
• Encouraging natural predators and parasitoids that help regulate cricket populations in the ecosystem.
