“…Gray buds showed the capacity to attain reproductive maturation under simulated overwintering environments, although female boll weevils consistently failed to oviposit on the flower buds of Sphaeralcea sp. under natural conditions (Bariola et al ., 1984; Palumbo et al , 1990). Sphaeralcea flower buds may contain chemical deterrents that prevent reproductive females from depositing eggs.…”

“…High numbers of adult weevils captured in pheromone traps during overwintering months may be physiologically active and seeking hosts (Bariola et al , 1984). The habitats of overwintering weevils are not known; however, alternative foraging resources play a significant role in adult boll weevil survival, especially during cotton‐free periods (Jones et al , 1993; Hardee et al , 1999).…”

Reproductive potential of field‐collected overwintering boll weevils (Coleoptera: Curculionidae) fed on pollen in the laboratory

The reproductive potential of overwintering boll weevil, Anthonomus grandis grandis (Boheman), females collected from pheromone traps in September, November and January, fed for 1, 3, and 5 weeks on plant pollens, and then provided cotton squares, was determined in the laboratory at 27 ± 1• C, 65% RH, and a photoperiod 13 : 11 (L : D) h. Duration of pollen feeding by overwintering boll weevils did not significantly influence egg and feeding punctures, or puncture ratios (egg to total punctures) for any of the three months of parent weevil collections when provided cotton squares on a daily basis.

O objetivo do trabalho foi estimar a formação de carimãs em diferentes cultivares de algodoeiro e a sobrevivência dos bicudos no interior dessas estruturas vegetais. A formação de carimãs foi estimada nas cultivares de algodão FM 975 WS, FM 944 GL, FM 982 GL e FM 910. Maçãs secas (carimãs) de cada cultivar foram coletadas em 20 pontos amostrais em uma área de dois hectares. Os carimãs coletados foram transportados para o laboratório e dissecados para contagem dos bicudos adultos no seu interior. A sobrevivência de adultos do bicudo foi avaliada por meio da coleta de 750 carimãs da cultivar FM 910, dissecando-se posteriormente 50 carimãs a cada 15 dias, a partir da data de coleta até 210 dias, quantificando-se adultos vivos e mortos. Os adultos foram alimentados com botões florais de Hibiscus sp. até a morte. Os resultados demonstraram que a formação de maçãs secas que não se abrem (carimãs) varia com o tipo de cultivar de algodão escolhida para plantio. A grande maioria da população de bicudos aprisionados nos lóculos dos carimãs não sobrevive por longo período de tempo, embora uma porção bastante reduzida dessa população seja capaz de sobreviver e emergir dessas estruturas por mais de cinco meses.

“…Leggett and Fye (1969) reported that adults increased in remaining cotton stalks and survived through the winter until newly planted cotton was available in the spring. Large numbers of adult boll weevils captured in pheromone traps in the winter may indicate that overwintering populations may be physiologically active and seeking hosts (Bariola et al, 1984); however, researchers are still uncertain regarding the overwintering habitat. Alternative foraging resources play a significant role in adult boll weevil survival, especially in the absence of cotton (Jones et al, 1993;Hardee et al, 1999).…”

The survival of overwintering boll weevil, Anthonomus grandis grandis (Boheman), adults on non-cotton hosts in the Lower Rio Grande Valley (LRGV) of Texas was examined from 2001 to 2006. The success of the Boll Weevil Eradication Program, which was reintroduced into the LRGV in 2005, depends on controlling overwintering boll weevil populations. Laboratory studies were conducted using boll weevil adults that were captured in pheromone traps from September through March. The number of adults captured per trap declined significantly in the field from fall to the beginning of spring (3.5-7.0-fold). The proportion of trapped males and females did not differ significantly. The mean weight of boll weevil adults captured in September was 13.3 mg, while those of captured adults from November to February were significantly lower and ranged from 6.7 to 7.8 mg. Our results show that boll weevil adults can feed on different plant pollens. The highest longevity occurred when adults were fed almond pollen or mixed pollens (72.6 days and 69.2 days, respectively) and the lowest when they fed on citrus pollen or a non-food source (9.7 days or 7.4 days, respectively). The highest adult survival occurred on almond and mixed pollens [88.0%-97. 6% after 1st feeding period (10 days), 78.0%-90.8% after 3rd feeding period (10 days), 55. 0%-83.6% after 5th feeding period (10 days), and 15.2%-32.4% after 10th feeding period (10 days)]. The lowest adult survival occurred on citrus pollen [52.0%-56.0% after 1st feeding period (10 days), 13.3% after 3rd and 5th feeding periods (10 days), and 0 after 6th feeding period (10 days)]. Pollen feeding is not a behavior restricted to adult boll weevils of a specific sex or physiological state. Understanding how boll weevil adults survive in the absence of cotton is important to ensure ultimate success of eradicating this pest in the subtropics.
