PROTEINS, CARBOHYDRATES AND LIPIDS IN THE LARVAE, PUPAE AND ADULTS OF PECAN WEEVIL, CURCULIO CARYAE HORN

Abstract

Pecan weevil larvae, in the 4th instar, held at 20°C showed a rapid decline in fatty acids, carbohydrates and proteins with time. Regression analysis of the fatty acid data (with time) gave a best fit for a polynomial expression, whereas both protein and carbohydrate fit a logarithmic curve. The larvae at 20°C pupated in an average of 42 days. The average life span of adults fed sucrose water was 82 days.
