On the application of the field prepared extract of p. aduncum approximately 100 gr and t. vogelii approximately 20 Gr. Extract then was formulated as emulsifiable concentrate and wettable powder.
6.3.1 Security Formulations against natural enemies
Formulation of EC and WP mix t. vogelii and p. aduncum (1:5) against natural enemies of c. pavonanan i.e. Eriborus argenteopilosus did not cause the death of parasitoid males and females are left in contact with the EC formulation and residue of WP for 24 to 48 hours of treatment (table 6.1). The active ingredient of t. vogelii and p. aduncum are specific and relatively safe against natural predators of e. argenteopilosus. Syahputra (2005) States that the secondary plant compounds more toxic if administered through food than if applied in contact.
Testing the extract blend t. vogelii: p. aduncum (1:5) shows that the larvae fed on treatment eating equivalent LC50 concentration diparasit by as many parasitoid 65.78% whereas the control diparasit as much as 55.56%. Observations visually against the behavior of the pemarasitan e. argenteopilosus against the larvae of c. pavonana who are on the surface of a leaf containing vegetable insecticides residue is not different from controls.

pavonana also made observations of the pest population h. undalis and p. xylostella on the plant sample (Figure 6.4, Picture 6.5). The population of h. undalis emerge earlier compared the population of c. pavonana (Figure 6.3). The population of h. undalis increased on 21 HST and down on 28 HST, HST, 35 and 42 HST. The decline in this population also occurs due to high rainfall so many pests that couldn't survive. The larval population increased 49 HST back and declined again on the next pengamata. Statistical analysis against the pest populations h. undalis showed no real differences of treatment when compared with the control and the treatment
