Apogonia rauca

This large beetle is stoutly built with an average length between 7 and 8 mm. Body shining dark brown.^[2]

It is a major pest of Arachis hypogaea.^[3] Grubs fed on the nodules, rootlets and immature pods whereas adults damage leaves. Heavy infestations cause stunted plants. Both grub and pupal stages lasted for 60-75 and 7-10 days, respectively. They attack the plants throughout the peanut season from July to October.^[4] Grubs and adults can be eradicated by using monocrotophos and chlorpyrifos.^[5][6]

Apart from groundnut, they are found extensively on rose flowers. Small numbers appeared in April and infestations continued until the mid August with a break during June. Adults are also known to feed on guava leaves.^[2]
