“…Results of this study support these previous reports, but also suggest opportunity to reduce overwintering boll weevil populations through delayed planting of cotton. This tactic has been used successfully in other regions of Texas (Masud et al 1985, Fuchs et al 1998, and, based on seasonal patterns of survival observed in this study, could provide substantial benefits to boll weevil eradication efforts currently being conducted in the Lower Rio Grande Valley.…”

The overwintering ecology of the boll weevil, Anthonomus grandis Boheman, in the subtropics is poorly understood. Knowledge of seasonal patterns of host-free survival may be important to eradication efforts in the Lower Rio Grande Valley of Texas. The host-free survival of weevil cohorts emerging between 1 June and 3 November 1994 was examined. Weevils were fed either outdoors for 21 d (9 cohorts), outdoors for 28 d (6 cohorts), or under controlled conditions (29.4 ± 1°C, 13:11 [L:D] h photoperiod; 5 cohorts) for 21 d. Weevils were fed cotton (Gossypium hirsutum L.) squares or bolls, depending on availability in the field, and were subsequently held without food in the same environment in which they were fed. Survival of weevils fed outdoors exhibited a marked seasonal pattern in which greater survival was associated with the later cohorts. However, survival of cohorts fed and held under controlled conditions exhibited no seasonal pattern. When survival was adjusted for degree-day accumulations, using a base temperature of 12.8°C, differences in survival curves of weevils fed outdoors were reduced but not eliminated. During the periods of highest degree-day accumulations, most cohorts fed outdoors for 21 d exhibited greater survival than those fed outdoors for 28 d, and survival tended to be greater for weevils fed under controlled conditions than for weevils fed outdoors. These observations suggest the feeding period duration influenced subsequent survival. The observed influence of temperature on host-free survival suggests the opportunity to reduce overwintering weevil populations in subtropical regions through a delayed planting tactic.

“…Based on detailed studies of boll weevil diapause and overwinter survival (Rummel and Adkisson 1970, White and Rummel 1978, Slosser 1978, Rummel and Carrol 1985, a uniform delayed planting strategy was developed in the Texas Rolling Plains as a means to maximize suicidal emergence of postdiapause weevils (Slosser 1978). During the past decade, this program has significantly reduced losses to boll weevil and substantially increased the profitability of cotton production in the region (Walker 1984, Masud et al 1984. Several workers have suggested that a similar program of uniform delayed planting might effectively suppress damage by pink bollworm in the southwestern United States (Adkisson et al 1962).…”

“…During the past two decades, regional control programs for cotton pests have been implemented in several areas of the United States (Henneberry et al, in press). The more important of these include the Heliothis Management Program in Arkansas (Phillips and Nicholson 1979) and several management or eradication programs for boll weevil (Davich 1976, Andrews 1981, Hamer et al 1983, Masud et al 1984, Farr and Lane 1987, Summy et al 1988a, Brazzel 1989). Operational differences notwithstanding, these programs share one common denominator, i.e., the objective of obtaining effective control through an orga¬ nized and concerted attack on the pest population, rather than individual infestations.…”

“…It is important that the policy variable be constant in sign and the nearer the upper and lower bounds of parameters over many specifications, the more confident one can be about inferences made from results. A recent study by Masud et al, 1985b, used this method to evaluate economic implications of a regional uniform planting date (UPD) cotton production sys- tem on the Texas Rolling Plains and mainly concentrated on the UPD variable.…”

This study evaluated implications of increased bollworm problems in a 20-county area of the Texas High Plains relative to cotton yields and economic impact. Results did not indicate a serious effect of bollworms upon lint yield when insecticides were used for control. However, estimated annual reduction in farmer profit due to the bollworm for 1979-81 was over $30 million. Yields were estimated to decline about 300,000 bales without insecticide use and about 30,000 bales with insecticide use. This decline suggests potentially serious implications for the comparative economic position of cotton in this region if insecticide resistance were to develop among insect pests.
