Helicoverpa zea (Boddie) (Noctuidae) is a well-documented pest of agricultural crops throughout most of North and South America (Wilcox et al. 1956; Hardwick 1965, 1996; Kimball 1965; Tietz 1972; Covell 1984; Heppner 2003; Capinera 2005; Wagner 2005). Hardwick (1965), in proposing the genus Helicoverpa as distinct from Heliothis Ochsenheimer, noted the polyphagous herbivory of H. zea (see also Kimball 1965; Tietz 1972; Covell 1984; Heppner 2003; Capinera 2005; Wagner 2005), but made no mention… 
Morphological Characterization of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae: Heliothinae)
Important morphological characters of this species include: eggs with four micropylar openings, lined with 12 cells arranged in the shape of a rosette; pupa adecticous and obtect, with prominent spiracles; adults with the distal antennomere striate.
Attack and defense movements involved in the interaction of Spodoptera frugiperda and Helicoverpa zea (Lepidoptera: Noctuidae)
The fall armyworm, Spodoptera frugiperda and the corn earworm, Helicoverpa zea are among the main pests of maize and the interaction of these species and intraguild interaction is provided.
Larval Helicoverpa zea Transcriptional, Growth and Behavioral Responses to Nicotine and Nicotiana tabacum
It is suggested that an observed coincidental rise in cannibalistic behavior and regulation of proteases and protease inhibitors in H. zea larvae signify a compensatory response to induced plant defenses.
Study on Nature and Extent of Damage of Corn Earworm, Helicoverpa zea (Boddie) in Maize
It was revealed from the results that BARI Bhutta-7 was more susceptible to this pest, as it was found that the cob infestation rate was in linear progress.

In the area occupied with Bt-crops caused by their cost inefficiency, a highly important place belongs to the representatives of the order Hemiptera, which are insensitive to Cry-proteins of genetically modified insecticidal crops engineered to control the main pests from the orders Lepidoptera and Coleoptera with chewing mouthparts.
Cellular and molecular mechanisms of DEET toxicity and disease-carrying insect vectors: a review.
To protect humans from malaria, yellow fever, dengue fever, zika, and filariasis, as well as to reduce economic losses associated with crop damage, considerably more efforts are needed to characterize the interactions between insects and insect repellents/pesticides to develop more potent pest control agents.

Predatory and parasitic Lepidoptera: carnivores living on plants.
This paper summarizes the life histories of the known predatory and parasitic lepidopteran taxa, focusing in detail on current research in the butterfly family Lycaenidae, a group disproportionately rich in aphytophagous feeders and myrmecophilous habits.
The Rise and Fall of Tropical Blues in Florida: Cyclargus ammon and Cyclargus thomasi bethunebakeri (Lepidoptera: Lycaenidae).
The habitat, abundance, nectar sources, life history, and decline of endemic Cyclargus thomasi bethunebakeri is discussed and loss of habitat through coastal development is likely cause of this decline.
Invasion, Colonization, and Disturbance; Historical Ecology of the Endangered Miami Blue Butterfly
The Miami blue butterfly, Cyclargus thomasi bethunebakeri (Lycaenidae), which was widespread in coastal southern Florida in the last century, is now reduced to a few dozen individuals on a single
Caterpillars of Eastern North America: A Guide to Identification and Natural History
Given the dearth of accessible guides on the identification and natural history of caterpillars, Caterpillars of Eastern North America is a must for entomologists and museum curators, forest managers, conservation biologists and others who seek a compact, easy-to-use guide to the caterpillar of this vast region.

Butterflies of the Florida Keys
This volume begins with a brief introduction to the keys providing some of the geologic and geographic history of the area, and the biological diversity of species represented in continental butterfly faunas of neotropical forests, selected West Indian Islands, and Florida are compared and contrasted.

Field populations of the bean leaf roller, Urbanus proteus (Linn.) on snap beans, were highest during October in central Florida and mortality of eggs and the first 2 larval instars was greater than for later instar larvae which survived quite well in the field.
