What pest is identified as the rice water weevil?

The rice water weevil is identified as Lissohoptrus oryzophilus. This insect is a significant pest affecting rice crops, particularly in the United States and other countries where rice is grown. The adult weevils feed on the leaves of rice plants, which can lead to reduced vigor and yield. They lay their eggs in the water or on the stem, and the larvae develop in the submerged parts of the plant. The rice water weevil is particularly important to monitor because of its life cycle and the potential for damage during critical growth stages of rice production.

The other options listed pertain to different pests or organisms not associated with rice water weevils. Hydrellia griseola is a species of fly, while Nezara viridula is known as the southern green stink bug, and Triops longicaudatus is a type of tadpole shrimp. None of these options have the same relationship with rice crops as Lissohoptrus oryzophilus does. Understanding the distinct characteristics and impacts of various pests is crucial for effective pest management in agricultural practices.
