“…We have maintained newly emerged overwintering adult boll weevils alive in petri dishes on prickly pear (Opuntia sp.) fruit, common to Mesoamerican tropics and subtropics, for Ͼ3 mo (A.T.S., unpublished data), whereas overwintering boll weevils fed on cotton seedlings, terminals, or squares survived averages of 8.1, 45, and 80 d, respectively (Fenton andDunnam 1929, Hunter andHinds 1905).…”

Field experiments in the subtropical Lower Rio Grande Valley of Texas were conducted to determine the extent of adult boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), dispersal from cotton, Gossypium hirsutum L., fields during harvest operations and the noncotton-growing ("overwinter") period between 1 September and 1 February. Using unbaited large capacity boll weevil traps placed at intervals extending outward from commercial field edges, boll weevils did not move in substantial numbers during harvest much beyond 30 m, primarily in the direction of prevailing winds. From traps placed in fallow cotton; citrus; lake edge; pasture; treeline; sorghum, Sorghum bicolor (L.) Moench, and sugarcane, Saccharum spp., habitats during the overwinter period, the most boll weevils were collected in the fallow cotton fields and adjacent treelines during the fall. However, the greatest abundances of boll weevils were found in citrus orchards in the spring, before newly planted cotton fields began to square. One of the three lake edges also harbored substantial populations in the spring. Egg development in females was not detected between November and April, but in cotton fields most females were gravid between May and August when cotton fruiting bodies were available. Mated females, as determined by discoloration of the spermatheca, made up 80-100% of the female population during November and December but declined to approximately 50% in February. The lower incidence of mating indicates a reduction in physical activity, regardless of overwinter habitat, until percentages increased in March and April after cotton fields had been planted and squares were forming.

“…Everett and Ray (1964) concluded that boll weevils prefer squares weighing an average 319 mg, which are Ϸ11Ð12 d old and Ϸ6 mm in diameter (Jones et al 1975). Fenton and Dunnam (1929) stated that weevils most frequently deposited eggs in squares from 6 d old until 3 d before bloom. In squares Ϸ3 d from blooming, feeding punctures were more numerous.…”

“…However, not all developmental stages of cotton squares or bolls are preferred equally by ovipositing females, nor is it likely that all stages are equally suitable for development of weevil larvae. Fenton and Dunnam (1929) observed that egg deposition was most frequent in squares from 6 d old to 3 d before bloom, after which feeding punctures were more numerous. Cate et al (1979) reported that ovipositing females avoided squares Ͻ7 mm in diameter, whereas McGovern et al (1987) found that squares Ͼ8 mm were less preferred than smaller squares for oviposition.…”

Understanding the critical host plant factors that determine oviposition behavior and survival of boll weevil, Anthonomus grandis grandis Boheman, on cotton, Gossypium hirsutum L., is important for developing successful pest management strategies. However, published information is both conflicting and limited regarding how different cotton fruit sizes affect boll weevil oviposition choices and subsequent larval survival to adulthood. Consequently, we used a standard based on fruit size diameter to evaluate boll weevil feeding and oviposition punctures, and survival to adulthood on 10 different cotton fruit sizes: squares of diameter 1.5-2.0 (pinhead), 3.0-3.5 (matchhead), 5-6, 7-8, or 9-10 mm; candle; and bolls of diameter 10-15, 15-20, 20-30, or >30 mm. Oviposition and feeding punctures were significantly affected by cotton fruit size. Females did not oviposit in pinhead squares. The fewest eggs were oviposited in boll sizes >30 mm. The highest number of eggs was recorded in square sizes of 5-6 and 7-8 mm. Boll weevil survival to adulthood was highest on square sizes of 7-8 or 9-10 mm (58.6-59.7%). No survival occurred in matchhead squares or bolls >30 mm. Duration of development was longest on boll sizes of 15-20 and 20-30 mm (18.2-18.8 d). The growth index (percentage immature survival divided by immature developmental time) of female boll weevils was 2.8-fold higher in 7-8-or 9-10-mm diameter squares than in 20-30-mm diameter bolls. This study will improve our capacity to develop methods to predict fruit losses and changes in boll weevil populations in the field, given a starting density of fruit suitable for oviposition, and a corresponding initial population density of weevils.

“…Females fed on water and honey survived 24 to 102 days (Willard), and averaged about two weeks during August (Folsom) However, two larvae may mature on a large bollworm (Willard) ( Willard ) Life cycle. The incubation period averaged 24 hours in August and September (Fenton and Dunnam, 1929), a little less than 24 (Folsom, 1936) and 18 to 28 hours in Hawaii (Willard, 1927). At Tallulah, Louisiana, the feeding-growing period of the larva required only three days, as a rule, but four were sometimes needed in September and October (Folsom).…”
