Rusty grain beetle is one of the common insect pests in stored grains worldwide. I am curious of the lifespan of this pest. Anybody here in RG knows it?
ِِِِِِِِAdult female can begin laying eggs around 3 to 4 days after emerging from the pupa. . Eggs are laid singly or in clusters of two or three, and they hatch in 4 to 5 days and the larval stage is needs 11 to 19 days, and pupation takes 3 to 5 days. Larval development takes longer in drier conditions. Mated males have an average life span of 159 days, and mated females live about 208 days. Unmated beetles live longer, males up 275 days, and females up to 300.
