Abstract

There is a growing concern to use environmentally friendly pesticides including the use of plant-based pesticides. Given that bio pesticides are degraded easily, exploration and scanning to obtain new bio insecticides are continued to be practiced. One of the potential bio insecticides is bulian (Euderoxylon zwagerii). The bulian is a species of hardwood commonly used as construction material by the people of Jambi due to its resistance to termite and mold. The earlier research indicated that the sawdust of bulian is potential to treat Spodoptera litura F., an important crop pest. The purpose of this research is to develop active agents extracted from bulian sawdust to control pest crop especially C. Chalcites. The treatment include the application of bulian extract with concentration of 0,01%, 0,05%, 0,1%, 0,5%, and 1%. The smallest concentration of active extract with the strongest anti-feeding activity will be used as a reference for the following field studies of C. Chalcites. The results showed that, the higher the concentration of n-hexane extract is given, the higher the antifeedant activity of C. Chalcites. The smallest concentration that showed very strong anti-feeding of C. Chalcites is 0.5%

Abstract

The aim of this experiment was to study the effect of Carica papaya Linn seeds extract on pracopulation onthe reproductive function of swiss Webster female mice (Mus musculus L.). Parametric are: body weight, thenumber implantation, number live fetuses, number death fetuses and embryionic fetuses, post-implantationdeath, live fetuses were examined, libido and ovarium weight. The experiment was designed using thecomplete randomized design. The results tested using the DNMRT method. Treatment are control withoutCarboksil Metil Celulose (CMC) 1% (K0), control with CMC 1% (KCMC), Carica papaya ekstrac dosage 50, 75and 100 mg/kgbb (E50, E75 and E100). The results experiment showed that Carica papaya L. ekstrac candestroyed could disturbed the reproduction function, i.e disturbed accreation body weight for gestation, bodyweight mice 18 th day of gestation, decrease the number live fetuses, increase number death fetuses andpost-implantation death, there number embryonic resorption and body weight live fetuses treatment morelower concentrated control. But, no influence significant for number implantation and ovarium weight.
