Developmental and hormonal regulation of midgut remodeling in a lepidopteran insect, Heliothis virescens
Midgut tissue undergoes remodeling during metamorphosis in insects belonging to orders Lepidoptera and Diptera. We investigated the developmental and hormonal regulation of these remodeling events in lepidopteran insect, Heliothis virescens. In H. virescens, programmed cell death (PCD) of larval midgut cells as well as proliferation and differentiation of imaginal cells began at 108 h after ecd...
متن کاملMolecular analysis of Campoletis sonorensis virus DNA in the lepidopteran host Heliothis virescens.
Nucleic acid hybridization techniques were used to analyse the fate of Campoletis sonorensis virus (CsV) DNAs in naturally parasitized and virus-injected Heliothis virescens larvae. Viral DNA persisted in injected H. virescens larvae from 0 to 10 days post-injection but no increase in the amount of viral DNA could be detected. Similarly, no increase in the amount of viral DNA was detected in na...
متن کاملGeneration of a Transcriptome in a Model Lepidopteran Pest, Heliothis virescens, Using Multiple Sequencing Strategies for Profiling Midgut Gene Expression
Heliothine pests such as the tobacco budworm, Heliothis virescens (F.), pose a significant threat to production of a variety of crops and ornamental plants and are models for developmental and physiological studies. The efforts to develop new control measures for H. virescens, as well as its use as a relevant biological model, are hampered by a lack of molecular resources. The present work demo...
متن کاملEnzymes and resistance to insecticides in Heliothis virescens.
762 between the tracheoles and the internal tissues. In resistant insects phosphine slowly reacts with some component of the membrane which retards its entry but may slowly oxidize it to hypophosphite. Since this site is not the toxic lesion no harm is done. In susceptible insects phosphine is transported unchanged into the internal tissues where it disrupts sensitive redox systems thus generat...
متن کاملGenes encoding candidate pheromone receptors in a moth (Heliothis virescens).
The remarkable responsiveness of male moths to female released pheromones is based on the extremely sensitive and selective reaction of highly specialized sensory cells in the male antennae. These cells are supposed to be equipped with male-specific receptors for pheromonal compounds, however, the nature of these receptors is still elusive. By using a combination of genomic sequence analysis an...
