THE PEA WEEVIL. 5 There is a single generation annually, and the cadelle feeds onvarious kinds of stored foods and plant products and is alsopartially predaceous, as Chittenden* states that both larvae andadults attack and destroy other grain insects which theyencounter. Nevertheless, the cadelle is capable of causing con-. Figure 3. Cadelle, adult and larva, twice natural size. siderable injury and the treatment is the same as for the othermeal worms. The larvae of the cadelle have been reported frommany unexpected places, such as in sugar, in bottles of milk,in powdered hellebore, and boring through the parchment paperof jars of jams and jellies. In some of these places theyprobably occurred accidentally. Larva and adult are shown infigure 3. The Pea Weevil, Bruchus pisorum adult beetle is about one-fifth of an inch long, and thewing covers are marked with small black and white spots. Itlays eggs singly on the outside of the green pods in the field,and the larva tunnels through the pods and into one of the greenpeas. The insect does not mature until the peas have ripenedand have been harvested and placed in storage. Then it is com-mon to find a single round hole in a pea where the adult hasemerged. Sometimes nearly every pea has a hole in
