AbstractThe growth parameters for cotton (Gossypium hirsutum L.) were examined via optimization studies to determine if the observed values were optimal for the season lengths and weather patterns found in California and Nicaragua. The parameters observed for Nicaraguan cotton were further examined to determine if predation by boll weevil (Anthonomus grandis Boh.) of small cotton fruit (squares) could explain the observed discrepancies. All of the observed growth parameters except the fruit bud production rate for the Acala SJ II variety of cotton which is grown in California appeared to be reasonably optimal for California condition (i.e. boll weevil does not occur in California). By contrast, the parameters for the Nicaraguan variety were sub-optimal if boll weevil was excluded from the analysis, but near optimal if the population dynamics of pest were included.

Abstract The boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), can remain inside dry and deformed reproductive structures of cotton, Gossypium hirsutum Linnaeus (Malvaceae), known as dry bolls, during the cotton fallow to infest the next cotton crop. In this study, the influence of cotton cultivars and sowing densities on the formation of dry bolls was evaluated. In addition, dry bolls were dissected and internal structures that were related to boll weevil development were estimated. Finally, the presence and survival of boll weevils inside dry bolls were evaluated. The results indicate that the number of dry bolls, empty pupal cells, and emergence holes was influenced by cultivar and not by sowing density. Almost one-quarter (22.53%) of adult boll weevils examined was found alive inside the dry bolls after 10 weeks, which is slightly longer than the duration of cotton fallow in Brazil’s main cotton-producing regions. Therefore, remaining inside the dry bolls is an important survival strategy for boll weevils during the cotton fallow period, and cotton cultivars with a greater propensity for the formation of dry bolls might favour survival of the pest during this period.

Adequate Management

The feeding and oviposition behavior of boll weevil in new cotton cultivars is essential for an adequate management. The objective of this study was to evaluate the vertical distribution of squares punctured for feeding and oviposition of the pest in the cultivars NuOPAL, DeltaOPAL, FMT-701, FMX-910 and FMX-993, and record the most and least preferred times of feeding and oviposition. The number of squares used for boll weevil feeding and oviposition were evaluated weekly in three parts of plant canopy. It was observed that, regardless the cultivar, A. grandis preferred to lay eggs in squares located in the upper part and feed on squares in the middle and upper parts. The boll weevil preferred to feed on cultivar FMT-701 in the beginning of the period of cotton flowering and fruiting, and the cultivars NuOPAL, DeltaOPAL, FMX-910 and FMX-993 throughout the whole period of flowering and fruiting. A. grandis preferred to lay eggs on cultivars NuOPAL, FMT-701 and FMX-993 at the beginning and end of flowering and fruiting of plants, while the cultivars DeltaOPAL and FMX-910 are used for oviposition throughout the period of flowering and fruiting.

Com o objetivo de obter linhagens resistentes ao bicudo-do-algodoeiro (Anthonomus grandis Boheman), a Embrapa-Centro Nacional de Pesquisa de Algodão vem testando progênies oriundas de raças primitivas de algodoeiro herbáceo (Gossypium hirsutum L.) originárias do México e da América Central, que apresentam níveis aceitáveis de resistência ao bicudo. Em 1991 e 1992, as progênies em BC1F5 e BC1F6 oriundas das linhagens Texas 277, Texas 326 e Texas 1180, Texas 297, Texas 339, Texas 766 e Texas 1134, foram avaliadas com relação à resistência ao bicudo. O delineamento experimental utilizado foi o de blocos ao acaso, com seis repetições. A unidade experimental foi constituída por duas fileiras de 5 m, sob um espaçamento de 0,75 m x 0,20 m. As parcelas foram infestadas com adultos do bicudo recém-emergidos, a uma taxa de 10.000 adultos/ha. Aos seis dias após a liberação dos adultos, as parcelas foram pulverizadas com Cipermethrim, sendo realizadas em intervalos semanais. Foram procedidas cinco avaliações através da coleta de 33 botões florais ao acaso, por parcela. Os maiores níveis de resistência ao bicudo foram obtidos pelas progênies Texas 326-95-1, Texas 277-87-5, Texas 1180-99-2, Texas 297 e Texas 339, com redução de ataque de 44,0, 41,2, 32,0, 40,4 e 36,4%, respectivamente, em relação à testemunha CNPA 6H.
