Effects of Fenitrothion and Aminocarb, at Doses Giving Low Mortality, on Surviving Eggs and Larvae of the Eucalypt-Defoliating Chrysomelid Beetle Paropsis Atomaria Ol. Iii. Histological Changes in Treated Larvae.

Abstract

The treatment of larvae of Paropsis atomaria Ol. with low doses of fenitrothion or aminocarb caused disintegration of the cell structure of the alimentary canal, reducing food digestion and absorption [see preceding abstract, etc.]. The growth of the larvae decreased progressively as the dose increased, and the fat-body was reduced. Muscle damage was also evident.
