in dryland cotton in Grady County. Damage averaged 25 percent in some fields where 

 rain hindered controls. Light to moderate in Bryan, Garvin, and Cotton Counties. 

 Larvae averaged 5 percent and eggs 7 percent in Newcastle area, McClain County. 

 (Okla. Coop. Sur.). ARKANSAS - Infestations near normal for August. Of 6,972 

 fields surveyed, 5,475 infested and 1,505 needed controls. (Boyer et al.). 

 LOUISIANA - Egg counts increased in Red River Valley; indicates new generation. 

 (Tynes et al.). In Madison Parish, damaged squares in 104 of 109 plots. Infesta- 

 tions ranged 1-10 (averaged 3.5) percent in infested plots. Moths increased; 

 total of 116 H. zea collected. (Cleveland et al.). MISSISSIPPI - In delta counties, 

 moth collections increased but no eggs in terminals. Trap located top of 90-foot 

 building z'ecovered over twice as many H. zea as trap located at 6 foot level. 

 May indicate long range dispersal underway. Damaged squares averaged 0.8 (maximum 

 2) percent in 6 of 8 fields. (Pfrimmer et al.). Few eggs noted statewide. Survey 

 of late instar larvae from Noxubee County indicate 80 percent H. virescens . 

 (Robinson) . TENNESSEE - H. zea continues to increase sharply in rank cotton 

 throughout western areas. Eggs and larvae ranged 1-25 per 100 terminals. Eggs 

 on underside of leaves, on stems, squares, and down in plant. Much damage 

 expected where control not timed to kill small larvae. Further increase expected. 

 (Locke) . 



ALABAMA - Heliothis zea moth flights very heavy in south and central areas and 

 increased in northern areas. Egg laying heavy, counts of 5-100 per 100 stalks in 

 many south and central area fields. Very few moths observed in south areas. 

 (McQueen). GEORGIA - During period ending August 14, egg laying remained heavy 

 in southern areas, up to 100 eggs and 0-15 larvae per 100 terminals. (Womack) . 

 For period ending August 21, eggs ranged 0-52 (averaged 14) and larvae 2-30 

 (averaged 8) per 100 squares in 30 Randolph and Terrell County fields; some 

 difficulties in control (Womack); square damage light in Spalding County. 

 (Tippens) . SOUTH CAROLINA - In Aiken County, total of 1,512 moths recovered 

 from light trap during period August 9-12. (Nettles). In Florence County, popula- 

 tions continue to increase. In light trap collected 665 H. zea and one H. 

 virescens . (Taft et al.). Egg laying increased statewide. Appears to be no 

 distinct broods in fields, with first instar to full-grown larvae present in same 

 fields. Generally crop damage much lower than that caused by populations in 

 August 1970. (Sparks). NORTH CAROLINA - Larvae increased from less than 10 to 

 50+ in 1.5 weeks in Johnston County. Also increasing in Bertie County. (Bradley). 



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

 punctured squares averaged 16.7 (maximum 40.3) percent in 10 treated fields; 

 averaged 27.6 (maximum 51.1) percent in 12 untreated fields. (Cowan et al.). 

 OKLAHOMA - Infestations ranged 15-45 percent on cotton in Tillman County and 

 10-20 percent in Jackson and Marshall Counties. Moderate in Bryan and Garvin 

 Counties and in Cotton County. (Okla. Coop. Sur.). ARKANSAS - Young adults in 

 blooms in many fields. Of 6,972 fields surveyed, 5,755 infested and 1,708 needed 

 controls. (Boyer et al.), LOUISIANA - Expect another peak emergence from squares 

 on ground August 16-23. Populations still heavy in many fields. (Tynes et al.). 

 In Madison Parish, no weevils recovered from sticky traps. E>unctured squares 

 ranged 7-59 (averaged 25.9) percent in 109 plots. (Cleveland et al.). MISSISSIPPI - 

 In delta counties, punctured squares averaged 16.6 (maximum 62.5) percent in 7 

 of 8 fields. No weevils taken on pheromone- baited wing traps. (Pfrimmer et al.). 

 TENNESSEE - Damage heavy in late cotton. Control difficult due to rains and rank 

 cotton. Small boll damage heavy in fields where squares scarce. Migration to those 

 counties to north occurring where no infestations noted earlier in season. 

 Punctured squares in some of these areas as high as 60 percent. Further increase 

 expected throughout cotton-growing area. Many fields of older cotton have "cut- 

 out" and are no longer attractive to weevils in western areas. (Locke). ALABAMA - 

 Adults still heavy throughout south and central areas and major cotton-producing 

 areas of Tennessee River Valley. (McQueen). GEORGIA - During period ending August 

 14, punctured squares ranged 2-78 percent in Gordon County (Dyer, Womack); 

 increased in southern areas, punctured squares up to 85 percent in fields where 

 controls stopped or delayed. (Womack). For period ending August 21, punctured 

 squares ranged 0-35 percent in 30 fields in Randolph and Terrell Counties, where 

 control practices satisfactory (Womack); percent punctured squares, 7 in treated
