飞机喷洒青虫菌六号液剂防治马尾松毛虫

飞机喷洒青虫菌6号液剂,大面积防治松毛虫的试验表明,常量喷雾用菌剂1125—1500克/公顷和低量喷雾1500—2250克/公顷,2—3天后防效可达90％以上,而且具有明显的后效。但防治区低量喷雾的防治效率比常量快.青虫菌剂对林间天敌昆虫、鸟类、蜜蜂等均安全。     

A preliminary study on the use of tempe-based formula as a weaning diet in Nigeria

Tempe, an Indonesian mold fermented food, was prepared from cowpeasand soybeans using the traditional oriental process with modifications whereappropriate. Four complementary foods were developed from whole maizemeal or dehydrated fermented maize (ogi) flour fortified with eithercowpea tempe or soybean tempe. Wholesomeness and potentials of thevanilla-flavored foods as weaning diets were determined. The nutrientcontent of all the developed products were within the range prescribed bythe FAO/WHO pattern for processed weaning foods. The products hadloose bulk densities between 0.40–0.55 g/ml and packed bulk densitiesbetween 0.68–0.75 g/ml; reconstitution indexes were between92.30–104.00 g/ml; viscosities were 34.2–65.0 CP at 70 ^°C and45.0–76.9 CP at 30 ^°C. Total plate counts ranged from 3.2 ×10³ – 4.3 × 10⁴cfu/g; coliforms staphylococcus, mold, andyeast were absent in some of the products. The results on sensoryattributes showed that tempe-based weaning diets were comparable withMameal, a commercial product. Maize and maize-fortified diets wereslightly higher in packed bulk density. Fortification reduced the viscosityof the diets and the values reduced with increasing temperature. Tempe-based weaning foods reconstituted easily in hot water, while cookingdestroyed most of the microorganisms present. Maize-based tempefortified foods were relatively inexpensive and have potential as weaningfoods.
