MGI ,9 ,YGbiulE<? •.amrfnsl OL Lancaster Farming, Saturday, July 6,1974—11 To produce codling moth virus, for example, Dr. Bode and Douglas G. Baugher, reasearch assistant, rear large numbers of moths in a laboratory. In the process, larvae are produced. When the larvae are 10 days old, they are diets inoculated with the virus. In this manner larvae become infected. The virus enters susceptile cells within a larva and causes these cells to produce more virus like itself. As the new virus is produced, the infected cells are destroyed and the larva begins to die. By the time the larva dies, most of the internal tissues have liquified. This liquid contains 1 to 10 billion birus granules. When the skin of a larva is broken, out flows the liquid containing the virus. Virus-killed larvae are stored in a refrigerator until needed. For experimental applications to trees, the Penn State researchers add water and shake the mixture to create a suspension. The project is carried out within the Agricultural Experiment Station at Penn State * In field tests last year, Dr. Bode measured dosages of the virus in “larval equivalents.” One larval equivalent is the amount of virus obtained from one larva. The Penn Staters used about 50 larval equivalents of virus in one-gallon of water for each apple tree. The virus was sprayed with a backpack mistblower. This season about 25,000 larval equivalents of virus will be used in field experiments. Before insect viruses are acceptable for field use, something needs to be done to protect their life span, Dr. Bode stated. Applied to foliage, they are inactivated rapidly by ultraviolet radiation from the sun. Of all material tested to block solar radiation, powdered charcoal was the most ef fective at the Biglerville Fruit Research Laboratory. Virus suspensions containing powdered charcoal were more effective than virus used alone in reducing injury to fruit. Red Meat Increases May 1974 slaughter of meat animals in Penn sylvania was up for cattle, and sheep and lambs, but down for hogs, while calf slaughter remained the same from a year ago, ac cording to the Crop Reporting Service. Cattle slaughter increased 4 percent, sheep and lambs 8 percent. Hog slaughter was down 17 percent from May a year ago. Nationally, total red meat production was 7 percent more than a year ago and 4 percent more than April 1974. Beef production was up 7 percent from May 1973, veal was 7 percent higher, pork production increased by 10 percent, while lamb and mutton production was 25 percent less than a year earlier. Food Preparation All food preparation, done 1,000 years ago or done yester day, consists of the same basic operations: heating, chilling, cut ting, mixing, separation, retriev ing and turning, measuring, form ing and brewing. Almost all kitchen utensils perform one or another of these basic functions, despite the great variety of their forms. “The more, the merrier” shouldn’t be your slogan if it means overloading your boat.
