“…Para as condições do sudeste do Texas e do nordeste do México foram identificados grãos de polén pertencentes a 15 famílias de plantas (BENEDICT et al,1991), enquanto que no Mississipi (EUA) encontradas 82 famílias, 132 gêneros e 28 espécies, sendo as plantas da família Asteraceae (Compositae) os recursos mais explorados por este inseto (HARDEE; JONES e ADAMS, 1999). Na Argentina, Cuadrado e Garralla (2000) encontraram grãos de polén em bicudos procedentes de regiões produtoras de algodão associados às famílias Malvaceae, Compositae, Solanaceae, Euphorbiaceae, Amaranthaceae, Leguminosae (atualmente Fabaceae) e Polygonaceae.…”

RESUMO -O bicudo-do-algodoeiro (Anthonomus grandis Boheman) (Coleoptera: Curculionidae) é um dos principais fatores limitantes para a expansão da cultura do algodão. Ele apresenta diferentes aspectos biológicos e comportamentais que garantem seu sucesso na exploração do agroecossistema algodoeiro. O objetivo deste trabalho foi identificar os recursos alimentares utilizados pelo bicudo na safra e entressafra de cultivos de algodão localizados nos municípios de Iuiu e Correntina (BA) e em ambientes de Caatinga e Cerrado, contíguos aos algodoais, respectivamente. As coletas dos adultos foram realizadas no período de fevereiro a setembro/2013 por meio de armadilhas com feromônio. As amostras foram processadas para identificação dos tipos polínicos encontrados no aparelho digestivo dos insetos. Os resultados indicaram que a praga explora 22 famílias botâni-cas como fonte de alimento, das quais 16 na Caatinga e 5 no Cerrado. Nos bicudos coletados em algodão foram encontrados 8 gêneros botânicos em Iuiu e 10 em Correntina, sendo apenas três coincidentes aos dois cultivos (Angelonia, Mimosa e Myrcia sp.1). Grãos de Pólen de 26 gêneros de plantas foram identificados para Caatinga e 6 para o Cerrado, ocorrendo três gêneros comuns às duas áreas (Myrcia sp.2, Eucalyptus e Mimosa). O bicudo explora fontes alternativas de alimento nas principais regiões produtoras de algodão da Bahia, com destaque para a Caatinga, que apresenta maior quantidade de famílias e gêneros botânicos utilizados pela praga.Palavras chaves: Anthonomus grandis.

ALTERNATIVE POLLEN SOURCES FOR BOLL WEEVIL IN TWO COTTON GROWING AREAS OF BAHIA STATEABSTRACT -Cotton boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae), is one of the most limiting factors for cotton crop expansion. It presents different biological and behavioral aspects that ensure its success on this agroecosystem. This research aimed to identify pollen sources used by this insect during harvest and intercrop periods of cotton cultivations in Iuiu and Correntina -BA, Brazil; moreover, evaluating Caatinga and Cerrado neighboring areas. Adult insect samplings were made from February to September of 2013, through pheromone traps. Samples were analyzed to identify the pollen types inside the digestive system of insects. The results indicated that the pest explores 22 botanical families as nourishment source, from which 16 in Caatinga and five in Cerrado. Regarding crop samples, eight genera were found in Iuiu and Correntina, being three found in both areas (Angelonia, Mimosa and Myrcia sp.1). Pollen from 26 genera were identified for Caatinga and six for Cerrado, with three genera in common for both (Myrcia sp.2, Eucalyptus, and Mimosa). The boll weevil uses alternative sources of food within the main cotton growing regions in Bahia State, highlighting the Caatinga with most of the botanical families and genera explored by the pest.

“…Asteraceae, Cheno-Am and Poaceae pollen have been reported as alternative food sources. Pollen from 14 non-malvaceous plant families including Asteraceae, Cheno-Am and Poaceae was found in boll weevils captured in southern Texas and in northeastern Mexico (Benedict et al, 1991). Asteraceae, Poaceae and Cheno-Am pollen have been found in weevils captured in Tamaulipas, Mexico, Mississippi and Texas (Jones et al, 1993;Hardee et al, 1999;Jones & Coppedge, 1999).…”

“…Both the larvae and adults forage on pollen. The larval stage is restricted to foraging within flower buds and fruits of the cotton tribe (Gossypieae) of the Malvaceae (cotton family; Lukefahr & Martin, 1962;Burke & Clark, 1976;Benedict et al, 1991). However, the adults are not restricted and can fly to other flowering plants.…”

“…Initially, only taxa in the Malvaceae such as Abutilon, Callirhoë, Cienfuegosia, Hibiscus, Malvaviscus, Sphaeralcea, Sida and Wissadula were known as foraging resources for adult boll weevils (Coad, 1914;Gaines, 1934;Szumkowski, 1953Szumkowski, , 1954Stoner, 1968;Cross et al, 1975). Today, the list of adult foraging resources has expanded to include numerous non-malvaceous taxa (Benedict et al, 1991;Jones et al 1993;Jones, 1997;Hardee et al, 1999;Jones & Coppedge, 1999.…”

“…Pollen grains were identified and counted via compound light microscopy to the lowest taxonomic level possible based on comparisons with pollen from the Areawide Pest Management Research Unit Pollen Reference Collections. Chenopodiaceae and Amaranthus (Amaranthaceae) pollens are morphologically too similar to distinguish and were pooled as 'Cheno-Am' (Martin 1963;Benedict et al 1991;Hardee et al 1999;Jones & Coppedge 1999).…”

An unexpected outbreak of boll weevils, Anthonomus grandis , an insect pest of cotton, across the Southern Rolling Plains (SRP) eradication zone of west-central Texas, USA, was detected soon after passage of Tropical Storm Erin through the Winter Garden district to the south on 16 August 2007. The synchrony and broad geographic distribution of the captured weevils suggest that long-distance dispersal was responsible for the reinvasion. We integrated three types of assessment to reconstruct the geographic origin of the immigrants: (i) DNA fingerprinting; (ii) pollen fingerprinting; and (iii) atmospheric trajectory analysis. We hypothesized the boll weevils originated in the Southern Blacklands zone near Cameron, or in the Winter Garden district near Uvalde, the nearest regions with substantial populations. Genetic tests broadly agree that the immigrants originated southeast of the SRP zone, probably in regions represented by Uvalde or Weslaco. The SRP pollen profile from weevils matched that of Uvalde better than that of Cameron. Wind trajectories supported daily wind-aided dispersal of weevils from the Uvalde region to the SRP from 17 to 24 August, but failed to support migration from the Cameron region. Taken together the forensic evidence strongly implicates the Winter Garden district near Uvalde as the source of reinvading boll weevils.
