or ovipcfcsitor, which she uses for depofsiting the eggs. She 

 appears in April or May, and lays her long, transparent 

 white eggs in the opened or unopened blosisoms. In six 

 days the eggs hatch, and the small yellowish-white, 

 brown-headed larvae at once commence to feed on the 

 embrj^o fruit, each of which contains a score and upwards 

 of the maggots. By June most of the larvne are fully 

 developed, and the}^ either make their escape from the 

 fruit still on the branches or when it has fallen to the 

 ground, and then burrow an inch or so into the soil and 

 form silk cocoons. The larvae are said to jump from the 

 fruit to the ground. Some of the larvae do not pupate 

 till the following spring, while otheits do so almost at once. 

 Unfortunately, it is not j^ossible to detect the presence of 

 the maggots in the embryo fruit at first. It is not till 

 later that the unequal development of the fruit indicates 

 their presence. If a fruit be then cut open the interior 

 will be found hollow^ and black, and full of the maggots. 

 Crenerally, infested fruits begin to swell much earlier than 

 those not attacked. 



Remedies. — In the case of dwarf trees every abnormally- 

 devek)ped fruit should be picked off and burnt. If fallen 

 fruits are found on the ground, and these contain maggots, 

 burn them at once. Where trees have been badly attacked 

 the previous season, and there are evident signs of the 

 crop again being attacked, it is advised that the trees 

 should be sprayed with Arsenate of Lead (No. 10), so 

 as to kill the fruit and starve the larvae. Dress- 

 ing arable or pastural orchards with kainit at the rate of 

 five to ten cwts. per acre early in June, wheii the larvae 

 are beginning to fall from the fruits, is also strongly re 

 commended. Forking Strawson's Vaporite, or Apterite 

 or Kilogrub, into the soil at the rate of one ounce per 

 square yard early in June is said to kill the midges as they 

 emerge from the earth.
