“…The different insects in these samples were identified at the Insect museum of the Institute of Agricultural Research :AR), Ahmadu Bello University, Zaria, Nigeria. The aphids were first identified by ~e of aphid identification keys by Eastop (1961) and Martin (1983). The specific .dentity of the aphids were later confirmed by 1.…”

A study on the insects associated with green beans, okra, peas and cabbages was carried out at Vom and Riyom Agricultural Stations in Jos, Nigeria from October, 1980 to April; 1984. During the study period, a wide range of insects were found in association with green beans and okra plants. Sericothrips occipitalis, Empoasca spp., Aphis craccivora, Zonocerus variegatus and Bemisia tabaci were found on pea, green beans and okra plants while Myzus persicae and Brevicoryne brassicae were common on cabbage plants. Early infestation of okra and cabbage by Podagrica spp. and Brevicoryne brassicae respectively within the first three weeks after sowing, resulted in poor plant performance and low yield. Insecticide treatments reduced insect population on the treated plants and enhanced yield. In this study, insecticide treatments and the treatment of using ordinary water to hand wash aphids from cabbage plants bi-weekly, reduced aphid population on plants and increased crop yield. The number of insects on different experimental plants treated with Dichlorvos at 500, 750 and 1000g a.i/ha; pennethrin at 12.5g a.i/ha; deltamethrin at 7.5, 10.5, 12.5 and 17.5g a.i/ha, cypennethrin at 12.5g a.i/ha; carbofuran 3g at 100g a.i/ha was less than those on untreated plants.

“…While attempting to discriminate pseduobrassicae from erysimi, Hille Ris Lambers [16] could not find any characters that can differentiate the two and stopped short of making it a synonym. However, other workers considered pseudobrassicae as a subspecies of erysimi [17,18]. Despite this, erysimi continued to be used from 1975 onwards.…”

This chapter deals with brassica plants and their resistance to sucking pests—aphids. Brassica plants are known to synthesize a number of plant secondary metabolites which impart resistance to insect-pests and diseases. Aphids are known to feed primarily on sieve elements. The sieve elements in vascular bundles of angiosperms are important channels for nutrition. They are the channels of transport of photoassimilates from source to the sink. Because of the high nutrition content of the sap inside sieve elements, they are the target for many insect-pests and bacterial and fungal pathogens. Aphids are one such group of insects which target SE elements of phloem for nutrition. They are among the most important insect pests in agriculture particularly serious in temperate and sub-tropical climates. In addition to direct damage by feeding as well as toxic effects of saliva, the withdrawal of nutrients is detrimental to plant growth and development. In addition to this, aphids also cause indirect damage to plants by acting as vectors of plant pathogenic viruses. Furthermore, honeydew excreted by aphids provides suitable substrate for sooty molds that interfere with normal plant photosynthesis. In this chapter work on host plant resistance in Brassica plants against aphids has been reviewed.
