Entomologia Sinica 7 (1), 65-70
Abstract: The results of laboratory and greenhouse bioassays indicated that Rhodojaponin- III (Abbr. R- 1) and extracts of flowers from Rhododendron molle G. Don possessed signficant feeding inhibition and insectcidal properties against the larvae and adults of Liromyzia sativae. Treated with 500 mg/L R- III 1 000 mg/L molosul-tap, and 10 000 mg/L methanol(MeOH) ethyl acetate (EtOAc), CH₂Cl₂, methanol-water (MeOH-H₂O) extracts the rates of feeding inhibition were 77. 34 % 74.30 % 82.15 % 77.50 % 67. 33 % 62.85 % against the 2nd instar larvae, and were 67.66% 55.21 % 49.72% 54.26% 46.81 % 38.53% against the 3rd instar larvae, respectively;LC₅₀ values against the 2nd instar larvae were 208.65, 166.05, 2.74 ± 10³,766.72, 5.95 ± 10³, 1.85 ± 10³mg/L, and against 3rd larvae were 300.62, 256.00, 4.33 ±10³, 1.03 ± 10³,9.79 ± 10³, and 2.62± 10³mg/L, respectively. Against the adults, LC₅₀ values of R-III EtOAc extract and molosultap were 159.07.723.87 and 134.55mgL respectively after treatment for 24 h.
