 non-target insects following the fourth year of the High Plains Boll 

 Weevil Control Program. Tex. Tech. Coll. Entomol. Rep. 68-2 (Suppl.), 

 12 pp. 



The High Plains Boll Weevil Control Program of 1967 had ro roajor adverse effect 

 on the 1968 spring and early summer populations of beneficial insects found in 

 non-cultivated land. In past years data from both cotton and pasture have 

 indicated possible over-recovery in cotton in various areas in the control 

 zones; however, the 1968 data from pasture only indicate no differences be- 

 tween the areas within the control zones and the untreated area. In 1967 

 special emphasis was placed upon a test evaluating the comparative effect of 

 ultra-low volume Malathion and ultra-low volume Guthion on beneficial insects. 

 In general, the effects of Malathion and Guthion upon the non-target insects 

 were the same as the check and any apparent difference is probably due to 

 experimental variation. Only one cotton sample was taken before the first of 

 July due to the small size of the cotton. After further studies and statistical 

 analysis of ample data, comparison of 1968 data with past data can be expected 

 to yield more conclusive results.

In laboratory tests conducted in Mississippi in 1975, boll weevils, Anthonomus 

 grand is Boheman, were confused when the atmosphere was saturated with grand- 

 lure (I, (+)-cis-2-isopropenyl-l-methylcyclobutaneethanol; II, (Z)-3,3-dimethyl- 

 A^t^-cyclohexaneethanol; III, (Z)-3,3-dimethyl-A^ »°'-cyclohexaneacetaldehyde; 

 and IV, (E)-3,3-dimethyl-A^'°'~cyclohexaneacetaldehyde). In field tests, 

 grandlure did not cause confusion. Inhibition was indicated in field tests 

 when the 2 aldehyde components were used alone.
