Some biological aspects of the spider <em>Anelosimus studiosus</em> (Hentz) fed on first instar larvae of <em>Pectinophora gossypiella</em> (Saund.) and the second instar larvae of <em>Spodoptera littoralis</em> (Boisd.) were studied under laboratory conditions of 25±1ºC and 65±5% RH. The female life cycles spider averaged 78.5 and 85.48 days, while it was 83.83 and 75.1 days for male when they fed on the above prey, respectively. Adult female and male consumed (129.66 & 101.30) and (103.30 & 785.60) larvae of <em>P. gossypiella</em> and <em>S. littoralis</em>, respectively. Adult female lived for 39.3 and 41.3 days on <em>P. gossypiella</em> and <em>S. littoralis</em> and deposited an average of 41.7& 26.7 eggs when it fed on larvae of the above mentioned insects, respectively.

Three trade mineral oils B. W and Y were formulated as emulsifable concentrates in percentages of 94, 95 and 85, respectively. The physical properties of the mineral oils used indicated that, Y 85% EC mineral oil was the best one because it was more viscous, acidic and, its density and specific gravity were more than the other mineral oils. Also, the spray solutions of Y (85% EC) mineral oil for soft and hard waters were more effective than the other spray solutions of B 94% and W 95% EC mineral oils. The three mineral oils were evaluated against the adults of <em>Aphis fabae </em>and <em>Tetranychus urticae</em> under laboratory conditions, comparing with Kz oil “mineral oil” as control oil. The results indicate that the Y 85% EC exhibited that highest levels of relative toxicity (94.26) fold against <em>A. fabae</em>. The results of the tested mineral oil against the <em>T. urticae </em>showed very low level of R.T. Y 85% EC (8.31) fold, B 94% EC (2.49) fold and Kz 95% EC gave (47.47) fold. Y 85% EC showed the most effect against laboratory strain of <em>A. fabae, </em>followed by B 94% EC. Results indicated that the mineral oil Kz 95% was the best efficient against <em>T. urticae</em>.

The present study was carried out to evaluate the potential of the flower-bud powder and commercially available eugenol of <em>Syzygium aromaticum</em> against juveniles and adults of <em>Monacha</em> <em>cartusiana </em>using, baiting technique at three concentrations (10, 20 and 40 %) for bud-flower and (1, 2 and 4 %) for eugenol under laboratory and field conditions. The activity of both baits found to be time and concentration dependent, at the lowest clove-bud powder and eugenol concentration of 10 % and 1 %, mortalities were 67.5, 70, 75 and 47.5 %, respectively. However, the high mortality percentages (99, 100 and 100 and 97.5%) were obtained at concentrations of 40% and 4% clove-bud powder and eugenol for juvenile and adult snails, respectively 21 days after treatment under laboratory conditions, while under field condition reduction percentages were 39.6,57.2 and 62.4 % for adults snails at the three tested concentrations of clove-bud powder, respectively 21 days after treatment.
The molluscicidal concentration of both poising baits proved to be effective in killing both juveniles and adults <em>M. cartusiana</em> snail according to the period of exposure. Consequently, clove bud powder and essential oil (eugenol) of <em>S. aromaticum</em> appears to have a potential importance for land snails control in Egypt.
