Toxicity evaluation of Tracer, Palizin, Sirinol, Runner and Tondexir with and without mineral oils on Phylocnistis citrella Stainton

Abstract

The bioinsecticides are considered to be the best and effective pesticides. The main aim of this experiment was to determine the efficacy of Tracer (Spinosyn), Insecticidal Gel (Palizin), Insecticidal Emulsion (Sirinol), Runner (Methoxifenozide) and Tondoxir with and without mineral oils (MO) on the control of citrus leaf-miner (CLM),

phylocnistis citrella Stainton (Lepidoptera: Gracillariidae) in laboratory condition at 24, 48, 72 and 96 h post treatments. Leaves of citrus with second and third instars of leaf-miner larvae were used in all tests and the larval mortality were monitored. Analysis of variance showed that there were significant differences between reatments and control, and also significant differences were found among treatments. Tukay-Test among above treatments has shown that Tracer + oil, Runner and Runner + oil and Tondxir + oil with 98 ± 3. 2, 98 ± phylocnistis citrella Stainton (Lepidoptera: Gracillariidae) in laboratory condition at 24, 48, 72 and 96 h post treatments.

8.1 and 93 ± 5% mortality were more effective than MO, Tondxir and Sirinol + oil with 85 ± 8.3 and 81±7.2 and 78.25 ± 8.2% mortality and significant different with control (P< %1), respectively. Tukay-Test among 96 and 72 h post treatments with 77 ± 3.82 and 70.65 ± 7.5% of total mortality are more effective than 48 and 24 h post treatments with 52.27 ± 4 and 35.90 ± 3.8% of total mortality, respectively.
