THE PESTS OF GARDEN PLANTS 



BEAN WEEVIL 



Curculio (Otiorhynchus) pieties 



(with larva and chrysalis) 



to be the cause of the Potato murrain ; at another time the puncture 

 of Aphis rapce. was stated to be the undoubted cause of the Potato 

 disease. Our illustration shows the insect natural size and magnified. 

 Its body is green, and its head ochreous. The Colorado Potato 

 Beetle is a totally different insect. 



BEAN WEEVIL. This insect not only attacks Beans, but it at times 

 ravages Peas, Turnips, Savoy, Kale, Broccoli, Raspberries, Apples, 

 Pears, Vines, wall-fruit, &c. Its scientific name is Curculio (Otio- 



rhynchus}piripes, and our illus- 

 tration shows the larva, chry- 

 salis, and perfect insect. These 

 Weevils hide in the ground 

 during the day, and commit 

 their depredations entirely 

 during the night hours ; hence 

 one of the common names of 

 the pest is the Night-feeding 

 Weevil. These insects eat 

 holes through the stems and 

 leaves of Beans, and the larvse 

 during the autumn, winter, and spring months devour the roots of 

 garden and field crops. The beetle is clay-brown in colour, so that 

 when it is resting on the ground during the day-time it is impossible 

 for the sharpest eye to distinguish it from the surrounding earth. 

 No means are known for effectually protecting gardens against these 

 pests ; the best plan may possibly be to make the ground disagree- 

 able to them by dressings of soot or lime. 



THE PEA WEEVIL OR BUG (Bruchus pisi}. This pest attacks 

 Peas at the time of flowering or while setting the pods ; the beetles 



pair at this time and deposit 

 their eggs in the newly formed 

 Peas. The Peas when gathered 

 appear to be undamaged, 

 although they really contain 

 the larva of the Pea Weevil. 

 This larva eats part of the seed 

 and changes to the chrysalis 



form in the spring; the chrysalis then changes to a beetle, and 

 creeps out of the Pea as shown in our illustration, It then flies
