A simple apparatus to separate mosquito larvae from field collected samples.

Ecological studies of larval mosquitoes usuallv require collecting numerous samples. Mani, samples containing mosquito larvae contain substantial quantities of debris which must be separated from the larvae. This can be a tedious and time consuming task. Water claritv mav also make separation of larvae and pupae from the sample difficult. We developed a simple and inexpensive apparatus that can be used to seoarate larvae and pupae from field collected samples during ecological studies of larval mosquitoes in Argentina. The apparatus is reliable and saves time. The separator (Fig. 1) is constructed of a wide mouth, transparent, screw top glass jar (A) of the desired volume. Plastic may be used but
