DECIDUOUS FRUITS AND NUTS 



CODLING MOTH ( Laspeyresla pomonella ) - WASHINGTON - On apple near Yakima, Yakima 

 County. First-brood entries still occurring; overlap of first and second broods 

 likely. Second-brood moths expected about July 15 in earliest areas. Estimated 

 damage 50 percent on unsprayed trees. (Johnson). CALIFORNIA - Second-generation 

 moth populations of concern to walnut growers in San Benito County. Bio-control 

 about eliminated aphid populations on walnuts. Without aphid treatments, L. porao- 

 nella may require separate treatment. (Cal. Coop. Rpt.). UTAH - Moderate~in Salt 

 Lake, Davis, and Washington County orchards during period ending July 9. (Burning- 

 ham, Huber) . COLORADO - Second-brood moths taken in attractant traps in most of 

 Western Slope areas; counts variable. (Bulla). MASSACHUSETTS - Larvae very active 

 in unsprayed and poorly sprayed apple orchards in Hampshire, Hampden, Worcester, 

 and Middlesex Counties. (Wilder, Jensen). 



PLUM CURCULIO ( Conotrachelus nenuphur ) - MICHIGAN - Unusual number of larvae and 

 uncommon amount of damage noted in harvested cherries. Apparently due to poor 

 spray timing or controls used. (Thompson). 



SAN JOSE SCALE ( Quadraspidiotus perniciosus ) - WASHINGTON - First-generation 

 crawlers still emerging on peach, 30 days after first crawlers seen. (Johnson). 



PEACH TWIG BORER ( Anarsia lineatella ) - WASHINGTON - On peach trees near Yakima, 

 Yakima County. First summer generation shoot strikes noted July 7. (Johnson). 



TARNISHED PLANT BUG ( Lygus lineolaris ) - MASSACHUSETTS - Causing much damage to 

 peaches statewide. (Jensen) . 



PEAR PSYLLA ( Psylla pyricola ) - UTAH - Collected in Salt Lake County during period 

 ending July 9. This is a new county record. (Davis, Burningham) . MICHIGAN - Eggs, 

 nymphs, and adults from overlapping summer generations making effective control 

 difficult. (Thompson). CONNECTICUT - Difficult to control on pears in Glastonbury 

 area. (Savos, Kollas) . 



PEARSLUG ( Caliroa cerasi ) - UTAH - Damage moderate to cherry and pear foliage in 

 some Salt Lake and Davis County orchards (Burnigham) and severe in some Weber, 

 Cache, and northern Davis County cherry orchards (Davis) . 



CHERRY FRUIT FLY ( Rhagoletis cingulata ) MICHIGAN - Emergence complete in southwest 

 counties. Adults still numerous in traps north of Oceana County. (Thompson). First 

 larvae collected July 13 in Manistee and Oceana Counties. Recovered from tart 

 cherry samples at Hart. (Hanna) . 



APPLE MAGGOT ( Rhagoletis pomonella ) - MINNESOTA - Adults reported in two locations 

 in Lake Minnetonka area and at New Ulm. Only single specimens taken. (Minn. Ins. 

 Rpt.). WISCONSIN - Adult activity increased but still later and less intense than 

 in 1970. (Wis. Ins. Sur.). MICHIGAN - Light, erratic, and unpredictable through- 

 out much of State. Emergence about 2-3 weeks behind schedule for southern counties; 

 probably affected by recent drought. First flies trapped in Allegan and Kalamazoo 

 Counties July 12, (Thompson) . MASSACHUSETTS - Adult emergence increasing rapidly 

 statewide. (Jensen). CONNECTICUT - Adult emergence increased rapidly; collections 

 on false apple lures reported from Glastonbury, Bethel, New Haven, and Storrs. 

 (Savos , Kollas) . 



TWOSPOTTED SPIDER MITE ( Tetranychus urticae ) - MASSACHUSETTS - Causing some prob- 

 lems in apple orchards in Worcester and Middlesex Counties. (Jensen). COLORADO - 

 Building up in apple orchards in Mesa, Delta, and Montrose Counties. Range 2-10 

 per leaf, mainly in centers of trees. Miticide recommended in third cover spray. 

 (Bulla). Heavy in several peach orchards of Vineland area in Mesa County. (Sisson) . 



FALL WEBWORM ( Hyphantria cunea) - NORTH CAROLINA - Damaging over State. Second to 

 fourth instars infesting 30+ percent of pecans in Jones and Craven County area. 

 Webs observed on 1-5 limbs per tree. (Hunt). SOUTH CAROLINA - Light on pecans in
