Studies on the utilization of natural enemies as 'biotic insecticides'. Density effect in the mass culture of Pseudaphycus malinus Gahan


, : Studies on the utilization of natural enemies as 'biotic insecticides'. Density effect in the mass culture of Pseudaphycus malinus Gahan. Science Bulletin of the Faculty of Agriculture, Kyushu University 24(2): 161-166

In this further part of a series from Japan on the rearing of Pseudaphycus malinus Gah. for release against Pseudococcus comstocki (Kuw.) (see preceding abstract), it is stated that a density of 400 parasites/1000 hosts (on a single pumpkin) appeared to be the most satisfactory for mass-rearing. In the studies, the hosts were in the third instar.

Chemical identification of individual atoms in mixed In-Sn chains grown on a Si(100)-(2 × 1) surface was investigated by means of room temperature dynamic noncontact AFM measurements and DFT calculations. We demonstrate that the chemical nature o...

Background. The renal dynamic imaging method (modified Gate's method) with Tc-99m-diethylene triamine pentaacetic acid (Tc-99m-DTPA) is simple and less time consuming for glomerular filtration rate (GFR) estimation than other methods. Howeve...
