    The Development and performance of Cody alfalfa, a spotted alfalfa aphid resistant variety / (Manhattan, Kan.: Agricultural Experiment Station, Kansas State University of Agriculture and Applied Science, ), by T. L. Harvey (page images at HathiTrust; US access only). After becoming a professor of Entomology at the Division of Biological Control in , Dr. Hagen spent a significant amount of time throughout his career at the Gill Tract. He imported natural enemies that targeted a range of pests including blue and spotted alfalfa aphid, walnut aphid, pear psylla, acacia psyllid, plum aphid and pea aphid.

    Control of aphids (including greenbug aphid), armyworms, fall armyworms and stinkbugs in wheat and oats. Insect Pest Management Guide – complete book. Insect Pest Management Guide – Complete book. Sugarcane Beetle. The sugarcane beetle has been reported in all Southern states.   Some alfalfa cultivars are bacterial-wilt-resistant, such as 'Buffalo', 'Cayuga', and 'Ranger', while others are resistant to spotted alfalfa aphid, like 'Cody' and 'Zia', and to stem nematodes, such as 'Lahontan' and 'Washoe'. Historical Information. Alfalfa is .

      This sticky substance is a waste aphid product usually eaten by ants in the garden setting. Though harmless it can attract sooty mould and this disfigures the leaves. Lessen the problem by spraying any sticky leaves with tap water using an inexpensive .   To achieve a thorough understanding of plant-aphid interactions, it is necessary to investigate in detail both the plant and insect side of the interaction. The pea aphid (PA; Acyrthosiphon pisum) has been selected by an international consortium as the model species for genetics and genomics studies, and the model legume Medicago truncatula is a host of this aphid.

Trioxys complanatus Quilis (Hymenoptera: Aphidiidae) was introduced into South Australia in August as a primary parasite of the spotted alfalfa aphid Therioaphis trifolii (Monell) f.

maculata. Among important insect pests of alfalfa are the following: alfalfa weevil (Hypera postica), to which there are some resistant cultivars; spotted alfalfa aphid (Therioaphis maculata), and pea aphid (Acrythosiphon pisum), to both of which there are resistant cultivars; Potato leafhopper causing alfalfa yellows (Empoasca fabae) and meadow.

The appearance near El Centro, California, in February of symptoms of susceptibility in a lucerne clone that had been unaffected by Therioaphis maculata (Buckt.) in the three preceding years indicated the development of a biotype of the aphid that could reproduce on this and perhaps other resistant clones; the ability of T.

maculata to develop biotypes had already been noted [R.A.E., A 47 Cited by: 88 INSECT-PEST MANAGEMENT AND CONTROL spotted alfalfa aphid. When this insect in its early spread reached breeding nurseries, Lahontan, an improved variety resistant to the stem nematode, Ditylenchus dipsaci Filipjev, was quickly found also to be resistant to the aphid.

Interestingly for this special issue, an article by Stern et al. published 50 years ago on the control of the spotted alfalfa aphid Therioaphis trifolii is often referred as one of the works on which the IPM concept was elaborated. Below we shall see the main control methods available for Cited by: Biological Pest Control Scientists use different pest control methods that range from choosing a pesticide that will be least harmful to beneficial insects to raising and releasing one insect to attack another.

Biological control of horticultural pests is a subject of increasing interest, especially to people who prefer to use chemicals as little as possible. Single stems with one trifoliolate leaf from C-A1 (susceptible to Therioaphis maculata) and C84 (resistant to Th. maculata) were placed in aqueous solutions of aminoacids, sugars or juices extracted from the two varieties.

The cuttings were exposed to Th. maculata. Results indicated that the resistant clone possibly contains a level of some nutrients that is too low to support the by: 7.

The survival rates of spotted alfalfa aphid were reduced by % and %, respectively, compared to the control when aphids were treated with Msti and Msti in the selected alfalfa cultivars. These results were in line with the findings of the study conducted on mustard inhibitors [ 24 ].Author: Hailong Zhao, Hidayat Ullah, Mark Richard McNeill, Guilin Du, Kun Hao, Xiongbing Tu, Zehua Zhang.One other aspect of aphid pheromone communication is their use of alarm pheromones.

Interestingly, the main component of most aphid alarm pheromones is the branched chain sesquiterpene (E)-b-farnesene, whereas the alarm pheromone for the spotted alfalfa aphid is the cyclic sesquiterpene (-)-germacrene-A (Hardie et al., ).
