This investigation has been carried out to study the possibility of enhancing Trichoderma spp. with low dose gamma radiation for biodegradation of carbofuran pesticide. Five fungi strains are identified as Trichoderma spp. including T. harzianum and T. viride, Aspergillus niger, Fusarium oxysporum and Penicillium cyclopium. The results showed that Trichoderma spp. reached its maximum growth using carbofuran concentration of 200 mg/L (T. harzianum and T. viride, 167.6 and 222.0 mg/L respectively). On the other hand, Aspergillus niger reached its maximum yield 203.2 with 20 mg/L while the growth of Fusarium oxysporum and Penicillium cyclopium were dose dependence. This indicated that the isolates of Trichoderma spp. were potentially useful for carbofuran bioremediation after enchantment by low dose of gamma radiation. The biomass of Trichoderma spp. strain were increased and reached its maximum at 250 Gy of gamma radiation with Trichoderma spp. This dose showed increase in carbofuran biodegradation by 79% and 83.5% with T. harzianum and T. viride, respectively.

Afify, A. E. - M. M. R., Insecticidal activities of naphthalenemethanol, decahydro derivative and 1-phenyl,1-one, 2,4 hexadiyne of chloroform extract of artemisia monosperma by GC-MS spectroscopy, , 2016. Abstract

Two compounds from chloroform extract of Artemisia monosperma plant had been separated and identified as insecticidal activity. The purified fractions I and fraction II were separated and their chemical structure studied by GC-MS spectroscopic analysis. The results proved the presence of 2 - Naphthalenemethanol, decahydro - Alpha, Alpha, 4a,8-Tetramethyl-didehydro derive., [2R-(EZ Alpha, 4a alpha, 8 a, beta)} and 1-phenyl,1-0ne, 2,4 hexadiyne which having insecticidal activity against house fly. The above TLC purified fractions which had a single compound (By GC-MS analysis) gave 15 to 20 time more toxic as insecticidal than the crude chloroform extract. Then we could use these natural compounds as insecticidal activities instead of using synthetic compounds to protect human from diseases.
