Excerpt from Report of Observations of Injurious Insects and Common Farm Pests, With Special Report on Attack of Caterpillars of the Diamond-Back Moth, During the Year 1891: With Methods of Prevention and Remedy The past year has been remarkable for presence (more or less) of most of our common farm and garden insect pests, and also for bad attacks of several kinds of which the habits and means of prevention had been little recorded previously. To give the long list of infestations regarding which inquiries were received, would be for the most part a mere enumeration of our best known insect pests, as Wireworms, Daddy Long-legs, Carrot grubs, &c., but so far as I could judge by the reports sent to myself, there was a remarkable difference in amount of presence of some of our very commonest attacks. Some were present to an unusual amount, some unusually absent. Amongst corn attacks little was reported of Gout Fly (Chlorops), though it was mischievous to some degree, and very little either of Corn Sawfly, or Hessian Fly, or of the deformed growth in Oat plants, known as "Tulip-root, " caused by presence of "Stem Eel-worms." On the other hand Wheatbulb maggot was prevalent and injurious to a serious extent, Corn Aphis was more than usually reported, and a few attacks were observed of the malformation of grains in Wheat-ears, popularly known as "Purples, " or "Cockle-galls, " which are due like "Tulip-root" to the presence of Eel-worms, though of a different species of Tylenclius. The Mediterranean Flour Moth (see pp. 46-52) continues to spread its destructive presence in Wheat-flour mills and stores, and since my paper on the subject has passed through the press, I have been favoured from Dr. Charles Lindeman (the well-known authority on agricultural Entomology in Russia) with information of the pest having been discovered in a locality in Moscow, to which it had been imported from London in infested sacks. Reverting to attacks on the growing crops. Amongst Turnip infestations the very common attacks of Flea Beetle, Surface Caterpillars, and Turnip Aphis, were less reported than is often the case. On the contrary, Turnip and Cabbage-root maggots were very injurious in various places. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
