Última Silicon influence on the tritrophic interaction: wheat plants, the greenbug Schizaphis graminum (Rondani) (Hemiptera: Aphididae), and its natural enemies, Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) and Aphidius colemani viereck (Hymenoptera: Aphidiidae) Neotropical Entomology Moraes,Jair C.; Goussain,Marcio M.; Basagli,Marco A.B.; Carvalho,Geraldo A.; Ecole,Carvalho C.; Sampaio,Marcus V.. We studied the tritrophic interaction: wheat, greenbug Schizaphis graminum (Rondani) and its key natural enemies, Chrysoperla externa (Hagen) and Aphidius colemani Viereck, in plants with or without silicon fertilization. Treatments consisted of: 1) silicon application via the leaves; 2) silicon application in the soil 3) control (no application). The evaluations consisted of: a) free-choice aphid preference test in the laboratory, from the 35th day after plant emergence, and b) biological aspects of the immature stages of predator C. externa, feeding on aphids reared on plants from the different treatments. Two treatments were tried in the bioassays involving A. colemani: 1) silicon application in the soil, and 2) control (no application). The biological...

Ano: 2004 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1519-566X2004000500012 Effect of sodium silicate application on the resistance of wheat plants to the green-aphids Schizaphis graminum (Rond.) (Hemiptera: Aphididae) Neotropical Entomology Basagli,Marco A.B.; Moraes,Jair C.; Carvalho,Geraldo A.; Ecole,Carvalho C.; Gonçalves-Gervásio,Rita de C.R.. The green-aphid Schizaphis graminum (Rond.) is considered the major important pest of wheat plant, for causing severe injuries to the plants in all phenological crop stages, being able even to cause plant death. The objective of this study was to evaluate the effects of the application of silicon on the resistance of wheat plants to this pest. The experiments were carried out under greenhouse and laboratory conditions. The greenhouse experiment was conducted in a completely randomized experimental design with two treatments, consisting on silicon application and a control (without silicon application) with 10 replications and without environmental control. The laboratory bioassays were conducted under controlled environmental conditions (25 ± 1°C...
