weevil infestation counts were obtained through the operations office eacl. ..^ ak 

 and mailed to producers via the county agents. This was extremely helpful to 

 farmers wit:iin the area since they were able to use the scouts' reports in 

 determining when to apply insecticides for control. Overall, 64 different 

 newsletters were prepared and mailed to the farmers, amounting to 97,000 in- 

 dividual letters.

 the boll weevil in Oklahoma. Okla. Coop. Ext. Serv. [Rep.] CR-7172, 2 pp. 

 Sequential sampling is probably the quickest most accurate system of making 

 "treat-nontreat" decisions in insect scouting. This system usually reduces 

 sampling time by 50% over other methods. It has been used on a wide variety 

 of insects.

 9306, in control of Heliothis in cotton in U.S.Av Folia Entomol. Mex. 

 33: 15-16. 

 Bay NTN-9306 gave excellent control of Heliothis zea and H. virescens including 

 those resistant to organophosphorus compounds and good control of Alabama 

 argillacea , Spodoptera furgiperda and Lygus spp. In the control plots for 

 Heliothis spp. it gave good control of aphids, spider mites, whiteflies and 

 moderate infestations of Anthonomus grand is .
