Abstract:
Tomato leaf miner, Tuta absoluta (Meyrick) is a key and dangerous pest of Solanaceaus plant in Iran. Larva of the pest cause damage on different parts of host plants including leaves, stems and fruits. Excessive use of chemical insecticides quickly leads to pest resistance. Using plant-based compounds such as Carum carvi to control pests is a good alternative to chemical insecticides. This experiment was carried out in 5 main concentrations (10, 15, 20, 25, 40, 0 ppm) in five groups of 10 eggs.This Concentrations were determined using logarithmic distance and Samples were sprayed with manual spray. For this puropose one or two tomato leaves covered with wet cotton and foil (to prevent the rapid drying of the leaves) were placed in each petri dish, The specimens were examined daily and mortality and survival rates were recorded. The results indicate that this compound has a high potential for egg at LC50 = 23.22 & LC90 = 49.71, Intercept±SE= -1.038±.163, Slope±SE=4.30±1.160. The results showed that by increasing the Carum carvi concentration survival rates decreased. This experiment was carried out in five replications and 16: 8 photoperiod and 60 ± 5% relative humidity and 25 ± 5 ° C until hatching. In the present experiment, the Carum carvi reduced the emergence of the Tuta absoluta population. the results suggest that the Carum carvi has the ability to control tomato leaf miner. Also; the results so far point to the health of this compound for humans and other mamales, and it is recommended for use in IPM in order to protect the invironment and produce pesticide free products.
