Prosopis cineraria Druce, belonging to Leguminosae family, is a native plant in Bushehr province.
The seeds and pods of this plant are severely attacked by Caryedon serratus Olivier, and it is of utmost importance since the regeneration of this plant is through seeds. The integrated pest management of C. serratus, emphasizing the bioecology, natural enemies, and seed treatment with common pesticides of Confidor, Sevin and Phosphotoxin, was investigated in Bushehr province. The average length of oviposition period, larvae, and pupa was calculated to be 6.5, 24.5 and 10.5 days, respectively. The total period of life cycle from egg to adult was 42.5 days on average, and the number of pest generations was determined to be 5 to 6 generations per year. The predators like Carabidae beetles and ants feed larvae and pest eggs, respectively. The disinfection of seeds with Phosphotoxin insecticide showed the highest larval mortality rate (92.5%). For pest management, rapid collection of seeds and transfer to the storage at the time of arrival and pods fall, as well as disinfection of seeds with Phosphotoxin in storage areas is proposed.
