| Notes: | Label source: Beet or Mangold Fly - Grub of larva, leaf mined by grubs, chrysalis and drawings. Mangold fly lays its eggs in small patches on the undersides of Mangold or Beet leaves. The eggs are white, and oval, and are usually fixed by one end to the, leaf. As the maggot hatches it makes way through the egg shell at this end, into the leaf and there it feeds between the two sides, causing the blisters, or large patches, which destroy all the leafage. The maggots are whitish and legless. They feed for a, bout a month, and then turn into Chrysalids, - sometimes in the leaves, but more commonly they drop down and bury themselves for this purpose about three inches deep in the ground. The chrysalids are chestnut brown. In summer the flies come out in about a, fortnight, and start a new attack. They are ashy-grey, with dark markings, and with bristly hairs. There are two or more broods in a season, and the last brood commonly passes the winter in Chrysalis state, but sometimes the flies come out soon and liv, e through the winter. The best prevention of mischief from attack is a healthy growth. For this, good cultivation (in autumn if poss) is advised, together with a free use of fertilizers, as good farm manure, and superphosphate given with seed. Salt, an, d Potash Salt, or both, are also advised to be liberally applied to the land intended for mangold growing. Nitrate of soda, Guano, or other stimulating dressings are useful in case of attack, if rain comes to wash them in. Good drenchings of paraffin an, d water have answered well but the difficulty has been to prevent the paraffin separating from the water during application. For info. on this subject see case of cabbage aphis. Drawing infested plants when the crop is young, or pinching out the piece o, f leaf with the maggot in, lessens the amount of the next attack, but removed leafage should be destroyed. | ||||
