ABSTRACT
Effectiveness of Calcium Polysulphides against Pest Mite Egg Mortality Polyphagotarsonemus latus Banks and Eutetranychus banksi Mc.Gregor
Mites are pests of plants from the class Arachnida. Mites (Polyphagotarsonemus latus and Eutetranychus banksi) is an example of the most dangerous types of mites during the vegetative to the jatropha plant. The rapid of mites can invade and disrupt plant growth and cause a decline in agriculture, especially fruit. polysulphides calcium is one example of a natural pesticide made from inorganic minerals found in earth's crust. Advantages of calcium polysulphides as a natural pesticide is a pesticide inorganic among other environmentally friendly because it is faster components decomposed by nature, relatively cheap price, making the process easy, and is selective (only turn off a particular type of plant pests and relatively safe for natural enemies) . This study aims to determine the concentration of calcium solution polysulphides the most effective against pest mites egg mortality P. latus and E. banksi. type of research is real research (True experimental research). This study conducted in the laboratory entomology, Crop Research Institute for Tobacco and Fibre (BALLITAS) Malang, in the month from May to July 2010 with designs completely randomized design. Data collected by direct observation in the sample who had been given treatment.
