This book was released on 2018-08-16 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Control of Insect Pests in Manitoba The, best means of protecting against grasshoppers is the Criddle mixture. Devised by Mr. Norman t'riddle. To whom the agriculturalists of this province owe a lasting debt of gratitude. The basis of this mixture consists of horse droppings for which grasshoppers have a decided liking. Sixty pounds of horse droppings are poisoned by mixing in one pound of Paris green; two pounds of salt dissolved in half a pail of water are added and the whole is thoroughly mixed in a barrel. This mixture hi scattered broadcast round the infested or likely to be infested crop or field. Grasshoppers are also destroyed by means of hopperdozers which are devices for catching them as the trough-like hopper-dozens are dragged over the infested fields.

Download or read book Aphids on the World s Herbaceous Plants and Shrubs 2 Volume Set written by R. L. Blackman and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 1460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aphids are well-known as pests of agriculture, horticulture and forestry, but they are also one of the most biologically interesting groups of plant-feeding insects, and thus have attracted the attention of biologists in many research fields such as ecology, biodiversity, physiology, behaviour and genetics. Following the successful format of previous books on the world's aphids by the same authors, these two volumes provide a comprehensive species-by-species account of the aphids on the world's herbaceous plants and shrubs. They can be used not only as an identification guide and information source for entomologists and taxonomists throughout the world, but also as a unique database for studies of biodiversity and insect-plant relationships. In all, 3120 aphid species in 340 genera are covered, feeding on 2150 genera of host plants. Volume 1 features comprehensive host lists and keys to the aphids colonizing each plant genus. This information is supplemented in Volume 2 by a systematic account of all the aphid species, which provides information on their appearance in life, host range, geographical distribution and life cycles. There are 357 original line drawings, 252 photographs of slide-mounted specimens and 1000 references. Aphids on the World's Herbaceous Plants and Shrubs is the culmination of many years of work by two leading specialists and provides an essential research tool and standard reference work for entomologists in universities and research institutes throughout the world.
Download or read book Some Ant aphid Associations in Manitoba with Observations on Interactions Between Formica Oreas Comptula Wheeler and Aphids at Birds Hill Park Manitoba written by Mary Catherine Anne Madder and published by . This book was released on 1978 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: ... A survey of Manitoba ant-aphid associations was conducted by collecting and identifying samples of ants and aphids found together on aphid host plants. Qualitative and quantitative monitoring of the interactions of Formica oreas comptula with Symydobius americanus, Chaitophorus saliciniger and Pterocomma smithiae was carried out during 1977 at Birds Hill Park. Data were analyzed by stepwise multiple linear regression analyses. Twenty-seven species (seven genera) of ants tending 62 species (28 genera) of aphids on 39 host plants were collected in Manitoba during 1976 and 1977. Formica species were the dominant aphid-attendants and Aphis species wee the most frequently attended aphids. 9.7% of the associations contained two different ant species or genera together; usually one was the true aphid-attendant and the other a scavenger species. F. oreas comptula workers were always present at the aphid colonies, at least until mid-June; however, the individual aphid-attendants changed throughout the day and night. Demand for aphid honeydew diminished by mid-June, possibly due to departure of males and queens from the ant nest. Aphid excretory behavior changed when this decrease in ant attendance occurred, and other ant species were then frequently observed at or near the aphid colonies. Marking experiments suggested that age polyethism and task fidelity exist in F. oreas comptula, and that some ants which were present at the aphid colonies in the spring may have been foragers surviving from the previous summer ... F. oreas comptula were aggressive toward moving insects near the aphid colonies they were tending; they did not respond to syrphid larvae feeding on the aphids. Aphid parasitism and predation were not prevented by the ants' presence, and were greatest in colonies of C. saliciniger.
