nymphs ranged 2-4 per sweep in alfalfa and red clover in Queen Annes, Talbot, 

 Kent, and Caroline Counties. (U. Md . , Ent . Dept . ) . 



SOYBEANS 



MEXICAN BEAN BEETLE ( Epilachna varivestis) - INDIANA - Damaged soybeans in Morgan 

 Clark, Jennings, and Scott Counties. Infestations in central and south-central 

 districts represent extensions of damage range in State. (Matthew). 



SOUTHERN CORN ROOTWORM (Diabrotica undecimpunctata howardi) - KENTUCKY - Adults 

 per 100 sweeps averaged 35 in soybeans in Warren County, 5^0 in no-till soybeans 

 in Logan County. (Harnett). 



TWOSPOTTED SPIDER MITE ( Tetranychus urticae ) - MARYLAND - Light but slowly 

 increasing in several areas of Dorchester, Wicomico, Caroline, Talbot, Kent, and 

 Queen Annes Counties. Some yellowing along border rows in several fields in Queen 

 Annes County. (U. Md . , Ent. Dept.). 



PEANUTS 



LESSER CORNSTALK BORER ( Elasmopalpus lignosellus ) - OKLAHOMA - Increasing in Bryan 

 County peanuts. Currently moderate. (Okla . Coop. Sur.). 



COTTON 



BOLL WEEVIL ( Anthonomus grandis ) - TEXAS - In McLennan and Falls Counties, 

 punctured squares averaged 5.4 percent in 9 treated fields, averaged 6.3 percent 

 in 32 untreated fields. Infestations still light. (Cowan et al.). For Boll Weevil 

 in High Plains seepage 553. OKLAHOMA - Punctured squares ranged 25-30 percent in 

 early cotton in Blair and Warren areas of Jackson County. Ranged 2-3 percent in 

 other areas of Jackson County and in Tillman and Harmon Counties. Moderate in 

 Cleveland and Bryan Counties, light in Caddo County. (Okla. Coop. Sur.). 

 ARKANSAS - Adults emerging, infestations increasing. Of 7,202 fields checked, 

 4,215 infested; 300 or 4 . 2 percent needed treatment. (Boyer et al.). TENNESSEE - 

 Punctured squares ranged 1-83 percent in regularly infested cotton-growing area. 

 Most fields infested just above 10 percent control level. Dry weather caused 

 considerable reduction in larvae. Most of first generation emerged at this time. 

 If dry weather continues there will be definite reduction of second-generation 

 weevils which should start emerging by August 1. (Locke). LOUISIANA - Punctured- 

 square counts heavy in scattered fields statewide period ending July 19. Damage 

 levels earlier than usual in some fields. Expect punctured square counts to 

 increase next 10 days. Start control when 25 percent punctured squares observed. 

 (Tynes et al.). In Madison Parish, 28 weevils recovered from 190 wing traps; 

 total to date 5,040. Punctured squares averaged 8.8 percent in 8 of 15 fields. 

 Infestations in 84 of 96 plots checked. (Cleveland et al.). 



MISSISSIPPI - A. grandis infestations ranged 2.3-21 percent in 87 fields checked

 Calhoun Counties. (Sartor). In delta counties, punctured squares averaged 19.2 

 percent in 4 of 6 fields. Some fields treated. Collected 2 weevils in pheromone- 

 baited wing traps in Washington County. (Pfrimmer et al.). GEORGIA - Light to 

 heavy in southern area. (Womack, July 17). Punctured squares averaged 16 percent 

 in treated plots, 45 percent in untreated plots in Spalding County. (Tippins). 

 NORTH CAROLINA - Punctured bolls ranged 0-30 percent and 70-80 percent of bolls 

 dropped in 20 acres of cotton near Pembroke, Robeson County. Crop in maximum 

 fruiting stage. (Johnson). 



BOLLWORMS ( Heliothis spp.) - NEW MEXICO - Light and spotty in cotton surveyed in 

 Dona Ana County . (N.M. Coop. Rpt . ) . TEXAS - In McLennan and Falls Counties, eggs 

 averaged 7 (maximum 15.7) and larvae 8.9 (maximum 22) per 100 terminals in 9 

 treated fields. Eggs averaged 1.2 (maximum 10) and larvae 0.4 (maximum 4.6) per 

 100 terminals in 32 untreated fields. Damaged squares averaged 7 percent in 9
