THE Light reactions and feeding activity of larvae of the cutworm tryphaena pronuba l. (lepidoptera: noctuidae). part ii. field investigations
1964
MADGE, DAVID S.
Field observations are correlated with laboratory experiments (Part I). Instar I larvae are diurnal, instars III to VII larvae nocturnal and instar II larvae intermediate. The entry of instar I larvae into the soil is determined by decrease in light and fall in temperature. The activity of instars III to VII larvae is generally unaffected by temperature but is mainly related to absence of light. Instar I larvae are indifferent to moonlight; instar VII larvae are repelled by it.
