“…Square fed weevils produce more eggs and live longer than do those which feed on leaves or other structures, hence pp and p(t,O) depend on F(t,a,m). Isley (1928) reported that the square reared weevils have a life expectancy ll/z times that of weevils reared on bolls. Cushman (191 1) and Sterling and Adkisson (1970) investigated the mortality of boll weevils reared on a diet of squares.…”

Can. Enr. 109: 1359-1374 (1977) A general population model for cotton growth and development is presented. The model captures the essential properties of the biological processes, and is sufficiently flexible to the incorporation of complex physiological and behavioral characteristics. The model has been used successfully to simulate the growth and development of Acala SJ-I1 cotton in California. The mathematical framework for coupling plants and herbivores has been presented, and the biological implications of their damage to the plant examined in a very general way.

“…Boll weevils have been reported to prefer squares over bolls for oviposition and feeding (Hunter 1912, Howard 1921, and intermediate-sized squares (Hunter and Pierce 1912), 300 Ð 350 mg (Everett and Earle 1964) or 319 mg, on average (Everett and Ray 1962), are preferred. In terms of reproduction in the laboratory, Isley (1928) reported that diets of squares or small bolls were essential for reproduction and that boll-fed weevils oviposited signiÞcantly less than square-fed weevils. Adult female boll weevils fed on large squares (5.5Ð 8-mm-diameter) became gravid 3.8-fold more, and developed 4.8-fold more eggs, than females fed match-head (2Ð3-mm-diameter) squares, or postbloom (1Ð2-d-old), young (5Ð10-d-old), or old (3Ð5-wk-old) bolls (Showler 2004).…”

Relationships of Different Cotton Square Sizes to Boll Weevil (Coleoptera: Curculionidae) Feeding and Oviposition in Field Conditions

Feeding and oviposition preferences of the boll weevil, Anthonomus grandis grandis Boheman, for four different cotton square size classes in field conditions of the Lower Rio Grande Valley of Texas were studied during 2002 and 2003. Percentages of large (5.5-8-mm-diameter) squares used for oviposition and feeding were greater than pinhead or match-head squares. The preference for large squares as food and associated accelerated fecundity explain the substantial boll weevil population buildups that occur after large squares form. Medium-sized (3-5.5-mm-diameter) squares also were used but less than large squares. Feeding and oviposition on pinhead (1-2-mm-diameter) and match-head (2-3-mm-diameter) squares were negligible. Although planting date did not affect oviposition or feeding preferences for squares larger than pinhead and match-head sizes, the least amount of either damage to large squares was found in the earliest plantings during both years. This study indicates that pinhead and match-head squares, regardless of planting date, do not require pesticide applications to protect against boll weevil feeding and oviposition.

“…However, available estimates of oviposition or fecundity from laboratory studies have either omitted useful descriptions of the sizes and numbers of cotton squares provided to weevils (Cushman 1911, Isley 1928, Cole and Adkisson 1982 or if the number of squares provided were less than the average daily production of eggs (Lambert et al 1979, Roach 1979 and thus may have been limiting. Our objectives were to gain additional insight into the inßuences of square availability on potential population growth by examining the rates at which feeding and oviposition punctures are produced, and the survival of offspring in response to discrete levels of square availability.…”
