Alfalfa Weevils Influenced Parasitic wasps appear to be helping to control weevils which caused severe damage to alfalfa crops in the late 1950’s and mid 1960’5. The greatest effect of these parasitic wasps seems to be in areas of Pennsylvania where five species have become established, according to Dr. A. A. Hower, and Dr. Zane Smilowitz, en tomologists with the Agricultural Experiment Station at The Pennsylvania State University. Investigations by the Penn State entomologists indicate a definite correlation between the presence of certain parasitic species and population levels of the alfalfa weevil. The lowest weevil populations now exist in the southeastern counties. Various parasitic wasp SPECIAL FEEDER CATTLE SALE FRI., NOVEMBER 2, 2:00 P.M.

Ph. 717-354-4181 species were originally released in these counties in 1959 by en tomologists of the U. S. Depart ment of Agriculture. The heaviest populations of alfalfa weevil occur in the south central and southwestern counties, Drs. Smilowitz and Hower point out. Light to moderate numbers of weevils exist throughout the central and west central counties. In 1969, the two Penn State scientists initiated a research program to study the distribution and build-up alfalfa weevils-as well as the effect, if any, of parasitic wasps upon the weevils. Of the five established wasp species, four attack weevils in their larval stage. The fifth at tacks the adult weevil. All of the wasps deposit eggs inside live By Certain Parasitic Wasps alfalfa weevils which eventually die as a result of immature parasites feeding as larvae inside the weevils. Most noticable of all the parasitic wasps is one called Bathyplectes curculionis. This wasp is present in every region of the state. Adults of this wasp not only thrive when weevil larvae populations expand in the spring but also show some ability to produce more than one generation a year. Another very active wasp is Microctonus colesi. This parasite has increased and was present in all regions in 1972 and 1973. Establishment and build-up of another species, Microctonus aethiops, in the central and southern regions suggests that this wasp is vital, if not the most important, of the alfalfa weevil parasites. This wasp, which attacks the adult weevil, is found in greatest numbers in central and southeastern counties where it has been established the longest. The wasp destroys the reporductive organs of the adult weevil. Where M. aethiops is scarce or absent, the alfalfa weevil remains a serious pest among Holstein Banquet A former Lancaster County ag agent will be key speaker when the Lancaster County Holstein Association meets for its 23rd annual meeting and banquet Tuesday, November 6. The banquet will be held at the Good and Plenty Restaurant, Smoketown, beginning at 6:45 p.m Robert (Bob) Heilman, National Association Program Director for eastern New York state, will speak on “Science, Art and the Glamour of Our Business”.

Its spread and establishment has been very slow. To expedite build-up of M. aethiops in western counties, numbers of these wasps were collected in southeastern counties and transported to release sites in 1970 and 1971-and then more extensively in 1972 and 1973. Bathyplectes anurus, a, fourth species, appears to disperse slowly. It is a very prolific parasite once it becomes established. Since its initial release in the southeastern counties in 1963, it has remained essentially confined to that area. The fifth wasp, Tetrastichus incertus, contributes least to the control of the alfalfa weevil, in the opinion of Hower and Smilowitz. This parasite is most active during growth of the second and third crop of alfalfa. Prior to 1970 it was found throughout the state and m relatively large numbers. However, it has declined drastically in recent years and has even disappeared in the central and west central coun- ties. Its decline has come at the same time as a noticeable in crease in B. curculionis. Set For Nov. Robert D.

Minor Home Repairs Simple When it comes to doing small repairs around the house, even the most unhandy person can correct some things. Extension specialists at The Pennsylvania State University offer some in formation that might help in a pinch. For example, before painting a door, sand the edges. This prevents paint build-up that will cause the door to stick. If the lock on the door is tight or won’t turn, lubricate it with graphite which you can buy in a hardware store. If your dresser has a sticking drawer, look for shiny places on the top or bottom edges or on the sides. This will indicate where the drag is. Sand down these shiny areas. Rub the drawer and the frame where they touch with candle wax, paraffin or soap. If the drawers stick only in damp weather, the Extension specialists suggest you wait until the weather is dry and the drawers are not sticking. Then coat the unfinished wood with a penetrating sealer or with wax It the glides are badly worn, the drawer may not close all the way The drawer front strikes the frame, the drawer needs to be lifted. Remove the drawer and insert two or three large smooth head thumbtacks along the front of each glide That will be enough lift to make the drawer close PUBLIC SALE OF VALUABLE REAL ESTATE, FARM MACHINERY, PERSONAL PROPERTY & ANTIQUES On Saturday, November 3, 1973 at 10 A.M sharp at R D 2, Red Lion, Pa. m York Twp between Longstown and Cape Horn along Route 24.
