PROBLEM TO BE SOLVED: To provide a pest control agent for mosquito larvae that has small environmental burden and can efficiently control mosquito larvae with a small amount of agent.SOLUTION: Provided is a pest control agent for mosquito larvae characterized in containing an insecticidal protein against mosquito larvae that is produced by microorganism, in particular Bacillus thuringiensis, and an attractant for mosquito larvae. In said pest control agent, it is preferable that the attractant be an attractant also having an attracting action for predatory organisms of mosquito larvae. By applying the pest control agent to the habitat of mosquito larvae, mosquito larvae can be efficiently controlled with a small amount of active ingredients.SELECTED DRAWING: Figure 2【課題】環境負荷が小さく、少量の薬剤で効率的に蚊の幼虫を駆除することが可能な蚊の幼虫用駆除剤を提供する。【解決手段】微生物、中でもバチルス・チューリンジェンシス（Bacillus thuringiensis）が産生する、蚊の幼虫に対する殺虫性タンパク質と、蚊の幼虫の誘引物質を含有してなることを特徴とする蚊の幼虫用駆除剤。当該駆除剤において、前記誘引物質が、蚊の幼虫の捕食生物の誘引作用を併せ持つ誘引物質であることが好ましい。 当該駆除剤を、蚊の幼虫の生息場所に施用することによって、蚊の幼虫を少量の有効成分で効率的に駆除することができる。【選択図】図２
