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 treatments 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 ± 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.
