SJpplementary Notes 16 Abstract These proceedings include twelve contributed papers and the product of four working groups that either directly or indirectly address ways inwhich radar might be used as an observing tool for entomological studies and pest management in the United States. Population processes of flying insects are reviewed with emphasis on species where migration is a clear component of their life history. Known radar capabilities as they relate to insect detection and flight study are presented through several papers that relate actual field studies, and the prospects for using various types of radars are considered. The working groups developed a variety of project plans for the future use of radar as a field tool for insect flight studies. Specific recommendations are presented for entomological projects, a large scale pest management program, and various aspects of radar hardware development and data analysis necessary for effective implementation of the radar tool for insect oriented programs. 17.

From May 2-4, 1978 a multi-institutional body of forty scientists from Canada, Great Britain, and the United States attended this workshop and developed these recommendations, with no specific charge to direct them to any particular governmental agency. The detailed recommendations in the Summary, and in each session report, are useful for directing ongoing programs, as well as for developing new programs. There is no question that the use of radar in pest management can potentially lead to important changes in pest management practices, with annual benefits to society of hun­ dreds of millions of dollars. Specific attention was called to the fall armyworm: a moth only capable of surviving southward from the southernmost regions of the United States. By September each year close to $500,000,000 damage to agriculture is done as this species migrates northward to Canada. However, migration is a significant factor in the popula­ tion dynamics of many more species of pest insects than the fall armyworm. Yet for most such insects migration is not adequately understood, even though such an understanding is necessary to reduce effectively the annual loss to agriculture of billions of dollars. The basic problem lies in the present lack of techniques to observe this migration.

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

Pattemore3 and Melanie Hagen4 1Ecoinformatics & Biodiversity, Department of Bioscience, Aarhus University, Ny Munkegade 114, DK-08000 Aarhus C, Denmark 2Institute for Biodiversity and Ecosystem Dynamics (IBED), University of Amsterdam, PO Box 94248, 1090 GE Amsterdam, The Netherlands 3The New Zealand Institute for Plant & Food Research Limited, Private Bag 3230, Waikato Mail Centre, Hamilton 3240, New Zealand 4Genetics & Ecology, Department of Bioscience, Aarhus University, Ny Munkegade 114, DK-08000 Aarhus C, Denmark ABSTRACT Radio telemetry has been widely used to study the space use and movement behaviour of vertebrates, but transmitter sizes have only recently become small enough to allow tracking of insects under natural field conditions. 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.

The tribe Gazerini as previously delimited was found to be paraphyletic with respect to the genera Ceretes, Divana, Riechia, Frostetola, and Oiticicastnia. The genera Castnia, Geyeria, and Athis were also found to be non-monophyletic taxa. The mimicry pattern had multiple independent origins in the Neotropical castniids, and at least two lineages, Riechia and Prometheus, are involved in Batesian mimicry rings with unpalatable butterfly models in the tribes Acraeini and Heliconiini (Nymphalidae). We propose for Castniini 13 new synonymies and 27 new combinations. Geyeria strigata (Walker, 1854) is revalidated. The generic placements of Athis superba (Strand, 1912) and Castnia eudesmia Gray, 1838 are questionable, but presently upheld. © 2014 The Linnean Society of London, Zoological Journal of the Linnean Society, 2014, 170, 362–399. doi: 10.1111/zoj.12102 ADDITIONAL KEYWORDS: Batesian mimicry – new synonyms – taxonomy.

RESUMEN. Se colectaron nueve ejemplares pertenecientes a dos especies de la familia Castniidae: Athis delecta (Shaus, 1911) (un ejemplar) fue registrada en vegetación de Matorral y Athis inca oriza- bensis (Strand, 1913) (ocho ejemplares) en Selva baja subcaducifolia con elementos de Encino y Bosque mesófilo. Athis delecta representa un nuevo registro para Tamaulipas, mientras que la segunda especie se reafirma para Tamaulipas, pero es nuevo registro para Querétaro. The taxonomic knowledge of this family is limited mainly because they are very rare in natural ecosystems, their endemism, small geographical distribution, scarcity of specimens in scientific collections (Miller 1972, González & Fernández-Yépez 1993, Lamas 1993), and also there are limited studies on the group. Castniid moths are medium to large in size, from 20 to 110 mm; they are related to Cossidae and Hesperiidae, the distal portion of the antenna is similar to that of the Hesperiidae with a club and apiculus and the presence of three cubital veins on the wings. Few species are dimorphic in coloration although both sexes are similar in appearance (Miller 2000). At present almost 90 species belonging to 33 genera are recognized, even though some authors mention up to 106 different species (Lamas 1995, Miller 2000, González et al.

  • 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).

Yet we know very little about the complex migratory movements of these tiny animal migrants and less still about what causes their populations to fluctuate in space and time. Understanding the reason for these population level changes is important, especially for insect species that are agricultural pests and disease vectors.

  • Female Bias in an Immigratory Population of Cnaphalocrocis
    www.nature.com/scientificreports OPEN Female bias in an immigratory population of Cnaphalocrocis medinalis moths based on feld surveys and laboratory tests Jia-Wen Guo 1, Fan Yang1,2, Ping Li1, Xiang-Dong Liu 1, Qiu-Lin Wu1,3, Gao Hu 1* & Bao-Ping Zhai1* Sex ratio bias is common in migratory animals and can afect population structure and reproductive strategies, thereby altering population development. However, little is known about the underlying mechanisms that lead to sex ratio bias in migratory insect populations. In this study, we used Cnaphalocrocis medinalis, a typical migratory pest of rice, to explore this phenomenon. A total of 1,170 moths were collected from searchlight traps during immigration periods in 2015–2018. Females were much more abundant than males each year (total females: total males = 722:448). Sex-based diferences in emergence time, take-of behaviour, fight capability and energy reserves were evaluated in a laboratory population. Females emerged 0.78 days earlier than males. In addition, the emigratory propensity and fight capability of female moths were greater than those of male moths, and female moths had more energy reserves than did male moths. These results indicate that female moths migrate earlier and can fy farther than male moths, resulting more female moths in the studied immigratory population. To ensure the survival, reproduction and growth of their populations, animals have evolved a series of adaptive life history strategies, such as sex diferences in migratory strategies. Sex ratio bias is common in migratory ani- mals and afects population development1–3. sex diferences in reproductive behaviour and life history lead ani- mals to adjust the sex structure during migration to change population structure.
