اثر حشره‌کش ایندوکساکارب و سینرژیست پیپرونیل بوتوکساید روی سفید بالک گلخانه Trialeurodes vaporariorum Westwood (Hom.: Aleyrodidae)

Greenhouse whitefly (Trialeurodes vaporariorum) is a polyphagous pest with a large number of generations and one of the important pests of tomatoes. Many pesticides are used to control this pest and most of them have shown resistance. Indoxacarb (Avant), which is a non-systemic insecticide with a contact-digestive effect and belongs to the group of oxadiazine toxins, disrupts the insect's nervous system by blocking sodium channels. In this study, the insecticidal effect of Indoxacarb was investigated alone and with the synergist of Piperonyl butoxide PBO. Bioassay tests were performed using filter paper using Adult insects. These pests were performed in vitro at 25±1°C and 60±5% humidity at 16:8 L: D photoperiod. This pest was collected from the tomato plant of Varamin cultivar. Filter paper impregnated with different concentrations of Indoxacarb was cut into circles with a diameter of 6 cm. The experiment was performed with four replications, five concentrations, and 25 insects per replication. For the synergist test, doses of 200 ppm were prepared for synergist, respectively, and adult insects were exposed to the synergist 2 hours before use in the bioassay test. The results were calculated using Polo Plus software. The amount of LC50 was obtained 1225/5 mg / l. The experimental result was obtained by adding synergist 1831/39 mg / l. The results showed that the use of synergist with Indoxacarb was associated with an increase in LC50. Insecticidal properties are reduced by the use of synergists with pesticides. These results can be used for 4 methods and pests.
