A synthetic version is available which attracts rice weevils, maize weevils and grain weevils. Females produce a pheromone which attracts only males. Its gammaproteobacterial symbiont Candidatus Sodalis pierantonius str. SOPE is able to supply rice weevil with essential vitamins like pantothenic acid, riboflavin, and biotin. [7]

Most weevils have the ability to fly (including pest species such as the rice weevil), [2] [3] though a significant number are flightless, such as the genus Otiorhynchus, and others can jump. One species of weevil, Austroplatypus incompertus, exhibits eusociality, one of the few insects outside the Hymenoptera and the Isoptera to do so ...
Adult weevils create brown, rice-sized feeding pits. They chew through the leaf epidermis, and if prolonged feeding continues can create small holes in the leaves. Large weevil infestations can also cause severe leaf browning. Weevil larvae are internal miners and will eat the midrib of the leaf as they mature.
