Abstract:

When 4-, and 16-row trap plots were planted to cotton 2 weeks earlier than normal, both types of plots were equally effective in attracting overwintered Anthonomus grandis Boheman. When the plots were treated with aldicarb, a large proportion of the boll weevils that emerged before the squaring of the normal crop was attracted to the special plots and killed. When the plots were baited with grandlure, they attracted more of the boll weevil populations than plots that were not baited. Also, when trap plots were treated for control of Heliothis spp. 3 weeks after the sidedress application of aldicarb, the remainder of the fields did not require treatment against this pest until after insecticide was applied to control boll weevils. Plots sprayed with methyl parathion resulted in fewer Heliothis larvae than did aldicarb treatments.
