          Abstract

          Most studies on the family Noctuidae focus on very few species that cause damage to crops; however, there is little informatión on the biology and ecology of the remaining species of noctuid moths. This work examines the relationship of the larvae of Cucullia Calendulae with their main food plant Calendula arvensis. The results showed that the larvae of this species feed on the fruiting bodies, reaching an overall incidence of ca. 30%. In addition, there was a differential distributión of larvae according to their size. Early stages were found in the reproductive structures while latter stages were found on the stems, which should be due to a defensive strategy. Furthermore, from seven characteristics of the patch taken into account, only the height of the plant explained a greater number of larvae per patch.

          La mayoría de los estudios sobre la Familia Noctuidae se centran en aquellas especies que causan daños a los cultivos, existiendo muy poca información sobre la biología y ecología del resto de especies de la Familia. Este trabajo examina la relación entre la larva del nóctuido Cucullia Calendulae y su principal planta nutricia: Calendula arvensis. Los resultados mostraron que la larva de esta especie se alimenta de los cuerpos fructíferos de la planta, llegando a dañar hasta el 30% de los mismos. Además, existió una distribución diferencial por tamaños. Las larvas de los primeros estadios se encontraban en los órganos reproductivos, mientras las de últimos estadios se localizaban mayoritariamente en los tallos de la planta, lo que podría deberse a una estrategia defensiva. Por otro lado, de las siete variables analizadas, sólo la altura de la planta explicó un mayor número de larvas por parche.

              Migratory ecology of the black cutworm.

              The long-range migration of insects in general is briefly discussed here and serves as an introduction for in-depth inquiry into the migratory ecology of Agrotis ipsilon, the black cutworm. Zoogeography, pest status and injury, and seasonal occurrence of the species are reviewed. Circumstantial evidence of long-range movement of A. ipsilon moths within both hemispheres is presented, followed by experimental evidence of long-range movement of A. ipsilon moths in China and North America. Based upon experimental evidence published by several investigators, a theory is proposed of the existence of a thermal range (0-36 degrees C) for A. ipsilon pupae that acts as the precursor for adult (moth) migration. This theory should help explain the circumstantial and empirical evidence gathered upon the annual appearance and disappearance of this species over large geographic areas.
