MEADOW SPITTLEBUG ( Philaenus spumarius ) - MASSACHUSETTS - Counts of 20 adults per 

 100 sweeps in Hampshire County field. (Miller). WISCONSIN - Adults numerous in 

 most alfalfa swept in southern half of State. Counts 8-10 per sweep. (Wis. Ins. 

 Sur.) . 



THREECORNERED ALFALFA HOPPER (Spissistilus festinus ) - ARIZONA - Averaging 250 

 per 100 sweeps of alfalfa in Yuma Valley, Yuma County. (Ariz. Coop. Sur.). 



GRASSHOPPERS - MICHIGAN - Mostly Melanoplus f emurrubrum (redlegged grasshopper) 

 nymphs 292 in 20 sweeps of alfalfa in Ingham County. Watch field crops later in 

 season. (Ruppel, Romers). 



SOYBEANS 



SPOTTED CUCUMBER BEETLE (Diabrotica undecimpunctata howardi ) - TENNESSEE - Adults 

 4-5 per 10 stalks caused moderate damage to 2 inch tall soybeans in Franklin 

 County . (Cagle) . 



STRIPED BLISTER BEETLE ( Epicauta vittata) - IOWA - Damaged 20 rows (200 linear 

 feet each) in Ringgold County field July 7. Feeding on lower parts of soybeans 

 in Mahaska County (6 per linear foot), and Van Buren and Wapello Counties in 

 spots of 0.25-0.5 acre. Damaged end rows of field in Washington County July 7. 

 ( Iowa Ins . Sur . ) . 



THREECORNERED ALFALFA HOPPER ( Spissistilus festinus ) - ALABAMA - Adults light in 

 Dallas County. Occasional 10 to 20-inch plant falling due to earlier girdling. 

 (Smith et al. ) . 



GREEN CLOVERWORM ( Plathypena scabra ) - ILLINOIS - Still light, but situation will 

 bear watching. (SurT Bull . ) . 



PEANUTS 



A BURROWING STINK BUG (Pangaeus bilineatus ) - TEXAS - Increased slightly in Frio 

 County. Fields treated and excellent results obtained. (Green). 



LESSER CORNSTALK BORER ( Elasmopalpus lignosellus ) - TEXAS - Continuing to increase 

 in irrigated peanuts in Eastland and Comanche Counties. Most dryland peanuts 

 still small and only light infestations. Larval infestations in Hill County 10 

 percent and in Comanche and Eastland Counties ranged 0-26 percent. (Hoelscher) . 



COTTON 



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

 punctured squares averaged 3 (Inaximum 12) percent in 48 treated fields; in 11 

 untreated fields averaged 4.9 (maximum 27.3) percent. (Cowan et al.). OKLAHOMA - 

 Puncutred squares ranged 1-4 percent in Tillman County. Light to moderate in 

 Garvin County. (Okla. Coop. Sur.). AKRANSAS - Below control level in most fields. 

 Total of 6,935 fields surveyed ; 2 , 174 infested. Surveys indicate controls may be 

 needed in more fields than during 1970 for first-generation weevils. (Barnes et 

 al.). Punctured squares more than 50 percent in Pope County from overwintered 

 weevils. Numbers appear to be declining. (Boyer) . MISSISSIPPI - In delta counties, 

 punctured squares averaged 2.5 percent in 12 of 22 fields. In pheromone-baited 

 wing traps recovered 5 weevils in Washington County and 4 in Bolivar County. 

 (Pfrimmer et al.). ALABAMA - First "hatchout" of first generation on early jotton 

 over south and central areas. Egg laying in squares is general. Punctured 20-75 

 percent of squares in older fields in Greene, Dallas, Montgomery, Lee, and other 

 counties. Much cotton not fully fruiting and thereby first "hatchout" of weevils 

 just begun or not at all. Damage increased slightly in north area with occasional 

 small field approaching economic levels of 10-25 percent squares punctured. 

 Weather most favorable in 10+ years for survival of larvae and pupae in squares 

 during this first generation. (McQueen). TENNESSEE - Punctured squares ranged 10 

 to 32 percent in infested fields. Infestations heavier in older cotton. Control
