| Abstract: | The of XRD-473 is less toxic to four predacious natural enemies of citrus pests,- Amblyseius nicholsi Ehara et Lee. , Chrysopa bonicensis, Okamoto, Scolothrips takashii Prisner and Stethorus spp. in laboratory. The normal concentration, 50 mg/L has been used to test the effect of stomach poisoning, the mortality after 48 hr. was 20. 36,5. 18,7. 69 and 38. 33% respectively. The effect of contact poisoning to A. nicholsi was y = 3. 3986 + 3. 4166x, r = 0. 9330' , LC50=294. 25 mg/L,LC90=697.19 mg/L. |
