Oviposition behavior of Neomegalotomus parvus (West.) (Hemiptera: Alydidae): Daily rhythm and site choice
Anais da Sociedade Entomológica do Brasil 29 (3), 391-400
Abstract: Neomegalotomus parvus (West.) behavior related to choosing crevices of pigeon pea, Cajanus cajan (L.) Millsp., pods to lay eggs were studied. Blocking antennae, tarsi, eyes, abdomen, or all structures simultaneously, did not affect the site of the pod (crevices) chosen to lay eggs. Oviposition occurred mainly in the afternoon. Most eggs were laid from 4 to 6 pm. Females moved antennae alternately up and down. Dabbing/antennation was accomplished, first with antennae and then with antennae and labial tip and the ovipositor was exposed and swept over the surface of the pod, leading to oviposition. Eggs were held together with an adhesive substance. Mechanoreceptors were observed on the ovipositor.
