ABSTRACT CABRERA, JUAN CARLOS. Interactions between Spodoptera frugiperda (Lepidoptera: Noctuidae) and Bt-transgenic sweet corn. (Under the direction of Fred Gould and George G. Kennedy). Field experiments were conducted to investigate the effects of Cry1Ab toxin of Bacillus thuringiensis expressed in transgenic sweet corn (Attribute) on larval dispersal and larval density of the fall armyworm, Spodoptera frugiperda (Smith), which could affect rates of adaptation to Bt corn. Crop phenology and agronomy were also tested to determine the affects of rapid corn maturation and tillers on insect survival. Behavior and dispersal of larvae from the neonate to 10 day-old larval stage was measured in single variety plots of Bt and conventional plants. Each plot was artificially infested with one egg mass to test the hypothesis that Bt toxins affect larval behavior, increasing dispersal of early instars. Results indicated that crawling behavior of neonates was similar in both varieties but larvae settled faster on conventional plants. Larval dispersal among plants was also statistically similar in both varieties at all sampling dates. In separated plots, two larval densities and three planting dates were studied. Mortality of fall armyworm larvae in Bt sweet corn was not density-dependent. Early entry of the corn plant into reproductive stage apparently affected larval survival. There is not differential larval utilization and survival in tillers versus main whorls of Bt and non-Bt plants. Insect adaptation to Bt toxins is likely affected by larval dispersal and rapid maturation of corn plants.

Origins of Six Species of Butterflies Migrating Through Northeastern
diversity Article Origins of Six Species of Butterflies Migrating through Northeastern Mexico: New Insights from Stable Isotope (δ2H) Analyses and a Call for Documenting Butterfly Migrations Keith A. Hobson 1,2,*, Jackson W. Kusack 2 and Blanca X. Mora-Alvarez 2 1 Environment and Climate Change Canada, 11 Innovation Blvd., Saskatoon, SK S7N 0H3, Canada 2 Department of Biology, University of Western Ontario, Ontario, ON N6A 5B7, Canada; [email protected] (J.W.K.); [email protected] (B.X.M.-A.) * Correspondence: [email protected] Abstract: Determining migratory connectivity within and among diverse taxa is crucial to their conservation. Insect migrations involve millions of individuals and are often spectacular. However, in general, virtually nothing is known about their structure. With anthropogenically induced global change, we risk losing most of these migrations before they are even described. We used stable hydrogen isotope (δ2H) measurements of wings of seven species of butterflies (Libytheana carinenta, Danaus gilippus, Phoebis sennae, Asterocampa leilia, Euptoieta claudia, Euptoieta hegesia, and Zerene cesonia) salvaged as roadkill when migrating in fall through a narrow bottleneck in northeast Mexico. These data were used to depict the probabilistic origins in North America of six species, excluding the largely local E. hegesia. We determined evidence for long-distance migration in four species (L. carinenta, E. claudia, D. glippus, Z. cesonia) and present evidence for panmixia (Z. cesonia), chain (Libytheana Citation: Hobson, K.A.; Kusack, J.W.; Mora-Alvarez, B.X. Origins of Six carinenta), and leapfrog (Danaus gilippus) migrations in three species. Our investigation underlines Species of Butterflies Migrating the utility of the stable isotope approach to quickly establish migratory origins and connectivity in through Northeastern Mexico: New butterflies and other insect taxa, especially if they can be sampled at migratory bottlenecks. -

Challenges and Prospects in the Telemetry of Insects

Here, we review the available literature on insect telemetry using active (battery-powered) radio transmitters and compare this technology to harmonic radar and radio frequency identification (RFID) which use passive tags (i.e. without a battery). The first radio telemetry studies with insects were published in the late 1980s, and subsequent studies have addressed aspects of insect ecology, behaviour and evolution. Most insect telemetry studies have focused on habitat use and movement, including quantification of movement paths, home range sizes, habitat selection, and movement distances. Fewer studies have addressed foraging behaviour, activity patterns, migratory strategies, or evolutionary aspects. The majority of radio telemetry studies have been conducted outside the tropics, usually with beetles (Coleoptera) and crickets (Orthoptera), but bees (Hymenoptera), dobsonflies (Megaloptera), and dragonflies (Odonata) have also been radio-tracked. -
Climate and Rice Insects
367 Climate and rice insects R. Kisimoto and V. A. Dyck SUMMARY limatic factors such as temperature, relative humidity, rainfall, and mass air C movements may affect the distribution, development, survival, behavior. migration, reproduction, population dynamics, and outbreaks of insect pests of rice. These factors usually act in a density-independent manner, influencing insects to a greater or lesser extent depending on the situation and the insect species. Temperature conditions set the basic limits to insect distribution, and ex- amples are given of distribution patterns in northeastern Asia in relation to temperature extremes and accumulation. Diapause is common in insects indigenous to the temperate regions, but in the tropics, diapause does not usually occur. it is induced by short photoperiod, low temperature, and sometimes the quality of the food to enable the insect to overwinter. Population outbreaks have been related to various climatic factors, such as previous winter temperature, temperature of the current season, and rainfall. High temperature and low rainfall can cause a severe stem borer infestation. Rainfall is important for population increase of the oriental armyworm, and of rice green leafhoppers and rice gall midges in the tropics. The cause of migrations of Mythimna separata (Walker) has been traced to wind direction and population growth patterns in different climatic areas of China. It is believed that Sogatella furcifera (Horvath) and Nilaparvata lugens (Sta1) migrate passively each year into Japan and Korea from more southerly areas. Probably these insects spread out annually from tropical to subtropical zones where they multiply and then migrate to temperate zones. Considerable knowledge is available on the effects of climate on rice insects through controlled environment studies and careful observations and statistical comparisons of events in the field, However, much more conclusive evidence is required to substantiate numerous suggestions in the literature that climatic factors are related to, or cause, certain biological events. -
Quantifying Dispersal in British Noctuid Moths
Quantifying dispersal in British noctuid moths Hayley Bridgette Clarke Jones Doctor of Philosophy University of York Biology September 2014 1 Abstract Dispersal is an important process in the ecology and evolution of organisms, affecting species’ population dynamics, gene flow, and range size. Around two thirds of common and widespread British macro-moths have declined in abundance over the last 40 years, and dispersal ability may be important in determining whether or not species persist in this changing environment. However, knowledge of dispersal ability in macro-moths is lacking because dispersal is difficult to measure directly in nocturnal flying insects. This thesis investigated the dispersal abilities of British noctuid moths to examine how dispersal ability is related to adult flight morphology and species’ population trends. Noctuid moths are an important taxon to study because of their role in many ecosystem processes (e.g. as pollinators, pests and prey), hence their focus in this study. I developed a novel tethered flight mill technique to quantify the dispersal ability of a range of British noctuid moths (size range 12 – 27 mm forewing length). I demonstrated that this technique provided measures of flight performance in the lab (measures of flight speed and distance flown overnight) that reflected species’ dispersal abilities reported in the wild. I revealed that adult forewing length was a good predictor of inter- specific differences in flight performance among 32 noctuid moth species. I also found high levels of intra-specific variation in flight performance, and both adult flight morphology and resource-related variables (amount of food consumed by individuals prior to flight, mass loss by adults during flight) contributed to this variation. -
Appendix A: Monarch Biology and Ecology
Appendix A: Monarch Biology and Ecology Materials for this appendix were adapted from MonarchNet.org, MonarchJointVenture.org, MonarchLab.org, and MonarchParasites.org. Monarch Life Cycle Biology: Overview: All insects change in form as they grow; this process is called metamorphosis. Butterflies and moths undergo complete metamorphosis, in which there are four distinct stages: egg, larva (caterpillar) pupae (chrysalis) and adult. It takes monarchs about a month to go through the stages from egg to adult, and it is hormones circulating within the body that trigger the changes that occur during metamorphosis. Once adults, monarchs will live another 3-6 weeks in the summer. Monarchs that migrate live all winter, or about 6-9 months. Monarch larvae are specialist herbivores, consuming only host plants in the milkweed family (Asclepiadacea). They utilize most of the over 100 North American species (Woodson 1954) in this family, breeding over a broad geographical and temporal range that covers much of the United States and southern Canada. Adults feed on nectar from blooming plants. Monarchs have specific habitat needs: Milkweed provides monarchs with an effective chemical defense against many predators. Monarchs sequester cardenolides (also called cardiac glycosides) present in milkweed (Brower and Moffit 1974), rendering them poisonous to most vertebrates. However, many invertebrate predators, as well as some bacteria and viruses, may be unharmed by the toxins or able to overcome them. The extent to which milkweed protects monarchs from non-vertebrate predators is not completely understood, but a recent finding that wasps are less likely to prey on monarchs consuming milkweed with high levels of cardenolides suggests that this defense is at least somewhat effective against invertebrate predators (Rayor 2004). -
