A PUNCTUREVINE SEED WEEVIL (Microlarinus lareynii ) - OKLAHOMA - Adults reared 

 from puncturevine (Tribulus terrestris ) seed collected in Grady and Payne 

 Counties. These are new county records. (Okla. Coop. Sur.). 



A BRACONID (Trioxys pallidus ) - CALIFORNIA - Biological control by this species 

 of Chromaphis jugTandicola (walnut aphid) throughout most of State satisfactory. 

 This hymenopterous parasite introduced from Iran has become established in most 

 walnut-growing areas. Growers normally combine aphid and Laspeyresia pomonella 

 (codling moth) control; when aphid populations failed to develop, codling moth 

 control overlooked. Expect some nut damage. (Cal. Coop. Rpt.). 



MONARCH BUTTERFLY (Danaus plexippus ) - VIRGINIA - Adults moderate in Botetourt 

 and Roanoke Counties on September 26. (Miller). 



FEDERAL AND STATE PLANT PROTECTION PROGRAMS 



COMSTOCK MEALYBUG (Pseudococcus comstocki ) - CALIFORNIA - Survey continued in 

 Strathmore, Tulare County area. Three properties suspect. Recent finds in 

 Strathmore and Porterville received treatment. Treatments of infested plants, 

 other than mulberry, accomplished. In Lindsay, mortality counts made in treat- 

 ment area. So far kill has been excellent. (Cal. Coop. Rpt.). 



EUROPEAN PINE SHOOT MOTH (Rhyacionia buoliana ) - OREGON - Surveys of infested 

 areas in Umatilla County showed no infestations at Hat Rock and Umatilla; light 

 populations detected in Port of Umatilla area. Heavy at McNary Dam where controls 

 may be needed in 1972. Estimated 9 percent of pines in Hermiston which were 

 sprayed in 1969 sustained light damage this year. Compares with 7 percent in 

 1970. Appears that little population increase occurred during 1971. (Larson). 



GRASSHOPPERS - KANSAS - During annual fall survey, an estimated 710,000 acres of 

 cropland infested with 8 or more per square yard. Primarily in north-central, 

 central, and northeast crop districts. In these areas, dominant species, Melanoplus 

 bivittatus , M. dif f erentialis , M. sanguinipes , and M. femurrubrum. Most heavy 

 populations Tound in submarginal land and legumes. Other areas with populations 

 averaging above 8 per square yard confined to Meade, Clark, Comanche, Barber, 

 Kiowa and Pratt Counties and include adjoining sectors of Ford, Edwards, Stafford, 

 and Kingman Counties. Heavy infestations in this area usually scattered and 

 especially found in dry alfalfa and short grasses. Dominant species, Aulocara 

 elliotti , Ageneotettix deorum , Philibostroma quadrimaculatum , Melanoplus coloradus . 

 Other range spe ies common. Aeoloplus turnvulli common in western areas, economic 

 importance questionable; at one locati'on (south of Arkansas River at Syracuse) 

 26 different species noted. Populations greater than 8 per square yard found in 

 all districts, but only in isolated fields. Parasite and predator populations 

 generally low statewide. (Bell, Hohnholt) . 



GYPSY MOTH (Porthetria dispar ) - Male moths trapped in all but 2 MARYLAND 

 counties. Weekly shipments of Ooencyrtus kuwanai (an encyrtid wasp) continue 

 to States outside regulated area. Over one million specimens of this egg parasite 

 shipped for release, in ALABAMA, MARYLAND, NORTH CAROLINA, OHIO, VIRGINIA, and 

 in FLORIDA. TENNESSEE - To date all trapping negative. (PPD) . PENNSYLVANIA - 

 Numerous egg clusters found in plantation of Christmas trees east of Deer Lake, 

 Schuylkill County. (Kadow) . 



TULIPTREE SCALE (Toumeyella liriodendri ) - CALIFORNIA - Several infestations on 

 tulip trees in Sonoma , Sonoma County. Infestation of 3 to 24 per limb collected 

 by J. Sallee. Determined by T. Kono. This is a new county record and the 

 second known infestation. (Cal. Coop. Rpt.). 



ORIENTAL FRUIT FLY (Dacus dorsalis ) - CALIFORNIA - Male trapped at Pacific Beach, 

 San Diego County on September 30, determined this species October 1. Additional 

 trapping planned. Male reported previously September 8 at Garden Grove, Orange 

 County. See CEIR 21(39) :686. (PPD).
