اثر کنترلی قرص دورکننده آفات انباری (Mana®) و پودر دارچین بر جمعیت شب‌پره هندی Plodia interpunctella (Hübner)

The stored product pests are of important problems in agricultural products’ storage which cause considerable post-harvest damage. The indian meal moth, Plodia interpunctella Hubner (Lepidoptera: Pyralidae) is one of stored product pests with wide host range, specially dried fruits, in Iran and most parts of the world. High risk chemical fumigants are used to control this serious pest. Botanical insecticides are considered as suitable pest control tools in organic farming due low toxicity to humans, low persistence, and reducing side-effects on environmental. In this study, effects of cinnamon powder and a formulated herbal tablet (Mana®) (Mana herbal tablets were prepared by Kimia Sabz Company. According to the manufacturer, this pill is made from a combination of several plant powders (turmeric, cinnamon, pepper, black pepper) on biological characteristics and population growth of P. interpunctella on pistachio were evaluated at a temperature of 25.3 ± 0.04 ° C and relative humidity of 42.75 ± 0.11 and full darkness. The duration of larval stage of the control, cinnamon and the tablet was 35.46, 39.39, 47.91 days, respectively, which indicated an increase in larval period of the treatments as compared to the control. There was a significant difference in terms of intrinsic and finite rates of increase and mean generation time between treatments and the control. The intrinsic rate of population increase (r) in control, cinnamon and the tablet was 0.07, 0.053 and 0.04 day-1, respectively. The net reproductive rate (R0) was significantly different between the control and the tablet with the respected values of 18.64 and 37.24. The tablet and cinnamon powder caused 78.5% and 72.3% mortality during the pre-adult stages, respectively which were significantly different with 37.3% mortality in control. Herbal tablet caused the highest mortality rates in the larval stage (52%) and cinnamon led to the highest mortality in the egg stage (48.9%). The lowest fertility rate was observed in cinnamon with 108.11 18 18.02 and the highest fertility was observed in the control with 131.68 ± 15.02. Based on the results, cinnamon powder and the herbal tablet are evaluated as potent materials in the framework of integrated pest management of the Indian meal moth, because of the significant negative effects on its biological characteristics and population growth rate as well as safety for humans and the environment
