Meeting Abstract 92.5  Wednesday, Jan. 7  On the physiological determination of body size in Manduca sex: What is the critical weight? HELM, Bryan R*; DAVIDOWITZ, Goggy; University of Arizona bhelm@email.arizona.edu In holometabolous insects, adult body size is determined by exponential growth that occurs during the larval stage. As a result, 90% of growth occurs during the last […]

Meeting Abstract 92.1  Wednesday, Jan. 7  Competition of tyrosine with alkylphenols during shell hardening in new cuticle of lobsters CHEN, Ming*; JOCOBS, Molly/W; LAUFER, Hans; Univ. of Connecticut laufer@uconn.edu Alkylphenols, anthroprogenic estrogenic endocrine distrutors, were found in naturally occurring lobsters (Homarus americanus) with or without epizootic shell disease. We hypothesize that alkylphenols interfere in shell hardening during […]
