THE RASPBERRY MOTH. 35 



egg-laying tube, in the lateral region into the pulp. At each 

 penetration, Dr. Chapman believes that two eggs are deposited. 

 The whole process on one occasion occupied three or four minutes, 

 on another only about thirty seconds. 



The eggs are whitish, or nearly colourless, and lemon-shaped. 

 The larva, on hatching, commences to feed on the interior of a 

 seed, where it remains until the actual date of its leaving the 

 currant. In June or July it commences to bore its way out, and 

 spins a small, firm, white cocoon, which it attaches to the old 

 persistent bud scales or to the bark, and herein it passes the winter. 

 In the following spring it leaves the cocoon and bores its way into 

 the currant buds, and also into the young shoots. Here it again 

 commences to feed, and about the end of April becomes full-fed, 

 and enters upon the chrysalis stage, the moth appearing early in 

 May. 



PREVENTIVE AND REMEDIAL MEASURES. 



Spraying in the winter with soda and potash destroys many of 

 the caterpillars sheltering in their cocoons. 



All cuttings containing the larvae should be burnt. 



I am informed that the Blue Tit does much good in clearing 

 the larvae during their hibernating period. 



THE RASPBERRY MOTH. 



Lampronia rubiella, Bjerk. 



The caterpillars of this small rnoth were received from a 

 correspondent in May last, and later infested canes were received. 



LIFE-HISTORY. 



The eggs are laid on the raspberry flowers towards the end of 

 May or early in June, and hatch out in five or six days. The small, 

 pinkish-red larva remains within the raised receptacle upon which 

 the fruits are formed for a short time, but does not appear to feed 

 at all. It then either crawls off the plant or lowers itself down by 

 silken threads to the ground, on reaching which it makes its way 

 into the soil, and forms a small, flat, white cocoon, wherein it passes 

 the winter. The following spring, from March to April, it leaves 

 this cocoon, crawls up the cane, and makes its way into the base 

 of a bud, upon which it feeds. Later it eats its way into the pith 

 of the cane, just below the base of a bud, where it pupates, remain- 

 ing in this chrysalis stage for about three weeks. 



The pupa is about a quarter of an inch long, and on the dorsal 

 side of the last segment has a somewhat peculiar spine. In colour 

 it is orange-red, with the abdominal region almost pink. 



PREVENTIVE AND REMEDIAL MEASURES. 



Early in March paint the lower parts of the canes with a 

 mixture of soft soap and paraffin so as to prevent the caterpillars 

 from creeping on to the canes.
