Collecting Pests 



sawfly or the codling moth caterpillar, as the case 

 may be, leave them for their winter quarters. Pigs 

 make excellent collectors. Pears are often caused 

 to drop prematurely by the pear midge, the grubs of 

 which, hatched from eggs laid in the flower, live and 

 feed in the young pear to the number of about forty. 

 By mid-May the pear attacked has greatly increased 

 in size and often begins to turn black. All such 

 should be collected and destroyed before the grubs 

 fall out to the earth to hibernate. 



Both apples and currants are attacked at times 

 by the caterpillars of clearwing moths that 

 bore into the shoots and cause them to wither. 

 These shoots should be removed as soon as the 

 damage is apparent and burned with the culprit 

 inside. 



X. Shaking. — ^A few beetles are better collected 

 by shaking the attacked plants over a sheet spread 

 beneath than by any other method. The weevils 

 (OtiarrhyvAihus sp.) that attack fern-fronds, and leaves 

 and shoots of vines at night and other plants growing 

 under glass, are best dealt with so, and nothing is so 

 efEective when these same weevils feed upon raspberry 

 canes. When the dead unopened blossoms in the 

 trusses of the apple betray the presence of the apple 

 blossom weevil this method too should be used, but 

 in this case it wiU be effective in the dajrtime, while 

 in the other cases after dark is the best time, since the 

 weevils concerned generally hide in the daytime,
