Abstract
The present study was conducted to evaluate the biological performance of two botanical fine dusts of ploughman's and mexican tea grasses. It was found that the comparative calculated high means numbers of alive larvae in the untreated check (9.33±0.33) was significantly more or less decreased due to the performance of prepared baits of ploughman's fine dust at concentration rates of 1.0 up to 3.0 gm, and distinctly ended by the death of incipient adult-moths of the insect-pest. Versus, the revealed delayed effect of its higher concentration rate of 4.0 gm in the prepared bait, which gave the least detected values of mortality and malformed pupae (2.94 and 2.94%, respectively), which revealed its adverse biophysiological effects on the development of (f1) generation, followed by complete failure of (f2) 2nd one. Remarkably, all of the tested concentration rates of mexican tea grass fine dust alone (at 0.5, 1.0 & 2.0 gm) or / and admixed with the fine dust of ploughman's grass at rates of 1:1 or / and 1:2 gm caused rapid and complete failure of development of parent generation after larval treatment. Therefore, the extracted fine dusts for both evaluated natural plants (Mexican tea and ploughman's grasses) could be considered potential alternative to the use of conventional insecticides in the bait, as natural means in A. ipsilon control.
