“…The black cutworm, Agrotis ipsilon (Hufnagel), migrates in most of its range and is one of the few species for which complete two-way migration has been demonstrated experimentally , Showers 1997. In North America, a colonizing generation of A. ipsilon migrates northward in the spring , Showers et al 1989, Hendrix and Showers 1992 and a later generation migrates southward in the fall . It has been suggested that A. ipsilon enters reproductive diapause, or delayed maturity, before its annual southward migration because late in the season more males are attracted to light traps than to pheromone traps (Willson et al 1981, Levine et al 1982) and most females remain unmated Showers 1982, Clement et al 1985).…”

“…Identification of pollen found on or in an insect is used to determine the insect's feeding and migratory activities (Hendrix & Showers 1992;Gregg et al 1993;Lingren et al 1993Lingren et al , 1994Berkhousen & Shapiro 1994;Loublier et al 1994). Because some plants grow only in certain ecological zones or geographic locations, the identification of pollen from those plant species can be used to determine the geographical origin of the insect.…”

“…Hendrix & Showers (1992) found that black cutworm [Agrotis ipsilon (Hufmagel)] and armyworm [Pseudaletia unipuncta (Haworth)] adults captured in Iowa and Missouri contained pollen from plants that only grew in South and Southwest Texas. The identification of this pollen indicated that these insects migrated over 1300 km.…”

Os Usos do Pólen e suas Implicações na Entomologia RESUMO -Palinologia é o estudo dos grãos de pólen produzidos por plantas sementeiras (angiospermas e gimnospermas) e esporos (pteridófitas, briófitas, algas e fungos). O pólen representa a flora terrestre e pode ser útil em muitas disciplinas: é único, não deteriora facilmente e é um marcador natural. O pólen pode ser usado para determinar os mecanismos de polinização, os recursos de forrageamento, as rotas de migração e locais fontes de insetos e outros polinizadores. O pólen fornece meios para análises paleoambientais de rochas terrestres sendo de interesse de geólogos. Também auxilia a explicar as correlações de ambientes terrestres com as sucessões marítimas e é usado para determinar trocas ecológicas e ambientais. Recentemente, a palinologia tem sido utilizada nos meios forenses. Esse artigo introduz a idéia do uso do pólen em várias disciplinas e, em particular, na entomologia. PALAVRAS-CHAVE: Pólen, entomopalinologia, forense, aerobiologia.ABSTRACT -Palynology is the study of pollen grains produced by seed plants (angiosperms and gymnosperms) and spores (pteridophytes, bryophytes, algae and fungi). It represents the land flora and can be use in many different disciplines. Pollen is distinctive, does not easily decay and is a natural marker. Pollen can be used to determine pollination mechanisms, foraging resources, migration routes and source zones of insects and other pollinators. It provides a means for paleoenvironmental analyses of terrestrial rocks and is of interest to geologists. Pollen also aids in the correlation of terrestrial with marine successions and is used to determine environmental and ecological changes. Recently, palynology is used in forensics. This manuscript introduces the ideas of using pollen in a variety of disciplines, in particular in entomology.

“…From the pollen found on several species of butterflies and moths, Mikkola (1971) determined that some of these insects migrated to Finland. Hendrix and Showers (1992) Lingren et al (1993; found Citrus spp. pollen on corn earworm (Helicoverpa zea Broddie) adults that were captured in Oklahoma, indicating that the moths had migrated over 1000 km from South Texas.…”

Cotton pollen is thought to exist in the gut of boll weevils for at least 24 hours. Because finding whole or broken cotton pollen grains are valuable clues in determining when boll weevils were living in cotton, the retention of cotton pollen in the gut of the weevil was examined. Boll weevils were fed cotton buds, cotton flowers, and water for five days, then they were placed into cleaned cages without any food. However they were allowed to drink water freely. Weevils were examined at 0, 24, 48, 72, 96, and 120 hours after the buds and flowers were removed. One hundred weevils were dissected at each time interval, and each gut was placed onto a glass slide. Light microscopy was used to determine the presence or absence of cotton pollen. More weevils (63%) at 0 hours contained pollen than weevils at any other interval. Whole pollen grains were not found in weevils after 24 hours. The 120 hour interval contained a single weevil with pollen. In the laboratory test, whole cotton pollen grains indicated that feeding on cotton occurred within 24 hours. When only halves and fragments of pollen were found, cotton feeding occurred 48-120 hours earlier. Additionally, when six or more cotton pollen grains were found in a weevil, it had fed on cotton within 24 hours. This information narrows the boll weevil dispersal times and distances from cotton fields and overwintering areas.
