Infestations of insects such as corn earworm, Heliothis zea (Boddie), tobacco budworm, H. virescens (Fabricius), and fall armyworm, Spodoptera frugiperda (J.E. Smith), usually spread from southern to northern parts of the United States and Canada each year where they cause millions of dollars in economic losses. Since they do not survive the winter in these northern locations, they must disperse from their winter habitats each year. These winter habitats are assumed to be in the southern United… 
Migration and the Life History Strategy of the Fall Armyworm, Spodoptera Frugiperda in the Western Hemisphere
The fall armyworm, Spodoptera frugiperda (J. E. Smith), has a high reproductive rate of 900–1000 eggs per female, a relatively short generation time of 30 days and good dispersal ability. These
Migratory ecology of the black cutworm.
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, which should help explain the circumstantial and empirical evidence gathered upon the annual appearance and disappearance of this species over large geographic areas.

Identification of associations between atmospheric factors and noctuid population dynamics and migratory flights will improve the ability to predict infestations by pest species throughout their broad seasonal range expansion.
Insect Dispersal on Tenerife, Canary Islands: High Altitude Fallout and Seaward Drift
Insect dispersal on the large oceanic island of Tenerife was studied by sampling the "biological fallout" of insects (and other arthropods) on mountain snowfields and also collecting them from the
Radar observations of the spring migration into northeastern China of the oriental armyworm moth, Mythimna separata, and other insects
Abstract. 1. The spring migration of the oriental armyworm moth, Mythimna separata (Walker), and other insects into northeastern China was observed by radar at a site in central Jilin province.
Estimation of the Potential Infestation Area of Newly-invaded Fall Armyworm Spodoptera Frugiperda in the Yangtze River Valley of China
This study simulated and predicted the possible flight pathways and range of the populations using a numerical trajectory modelling method combining meteorological data and self-powered flight behavior parameters of FAW to understand the potential infestation area of newly-invaded FAW from the Yangtze River Valley.
Mosquito ecology in relation to land-use changes and potential West Nile virus in Newfoundland
The research provided the data needed to estimate the level of risk for human and animal exposure to West Nile virus and the impact of land-use on mosquitoes if the risk of vectored disease transmission increases due to enhanced mosquito breeding seasons.
Behavior and ecological genetics of wind-borne migration by insects.
Advances in knowledge of the genetics of migratory potential have provided a basis for understanding how the stochastic effects of the winds on destinations and the pattern of habitat distribution in space and time maintain variation in these traits in populations of wind-borne migrants.
The Ecology of Heliothis Species in Relation to Agroecosystems
As key pests of several agricultural and horticultural crops, the four species I have singled out for review have attracted an enormous volume of research work and the literature on their ecology, biology and management is vast.
Possible windborne transmission of giant willow aphid Tuberolachnus salignus (Gmelin) (Hemiptera: Aphididae: Lachninae) westward from New Zealand to Australia
It is demonstrated using the HYSPLIT air trajectory model that it is possible that the giant willow aphid was carried on a reverse trajectory from New Zealand to southern Tasmania, explaining its first appearance within 3 months in Australia and New Zealand.


Corn Earworm Moth: Vertical Distribution in Nocturnal Flight
Adult Heliothis zea (Boddie) were trapped at 15 levels in conical-type blacklight traps on a television tower, indicating that flights of corn earworm moths commonly occur at altitudes above 1000 feet and may further indicate mass migration of corn Earworm moth.
Observations of the flight behaviour of the army worm moth, Spodoptera exempta, at an emergence site using radar and infra‐red optical techniques
Studies were made in Kenya of the flight behaviour of African armyworm moths which had emerged from areas previously infested with‘gregarious’ Caterpillars, and moths were observed to disperse rapidly during their migration.
Corn Earworms: Capture of Adults in Light Traps on Unmanned Oil Platforms in the Gulf of Mexico
Four battery operated light traps located ca. 20, 46, 66, and 100 miles from shore were operated on unmanned oil platforms in the Gulf of Mexico from Sept. 11 to Oct. 21, 1973. All traps captured
Six cruises were made aboard ships in the Pacific during 1967 and 1968 to continue studies of trans-oceanic dispersal of insects. Specimens obtained together with new and modified equipment and
The Influence of Off-Shore Platforms on Insect Dispersal and Migration
Understanding of insect dispersal-migration, including behavior, physiology, and diversity of the species involved, has developed slowly and is concerned with return-flight, survival-based migrations.
An Operational Three-Dimensional Trajectory Model
Abstract A numerical model is developed to compute three-dimensional trajectories from operational wind forecasts generated by the six-layer primitive equation model of the National Meteorological
