Aphids grew faster with increasing temperature and CO2, but no reaction to water content was observed. Mobility of the young larvae within the first 8 days of life increased with increasing temperature. The mass of the aphid population [dw] grew 63% or 21% with increasing temperature or CO2 ...
but the relative importance of these forces compared to other ecological factors is unclear. We conducted a field experiment testing the effects of genotypic variation, abundance, and presence/absence of green peach aphids (Myzus persicae) on the growth, leaf nitrogen,...
Fallow fields, which are common non-crop habitats in agroecosystems, provide shelter for wild plants and animals near agricultural fields1 and are often affected by herbicide drift from fields. However, there have been very few studies on the effects of herbicides on the plant communities in ...
In olfactometer bioassay experi-ment, aphids showed a preference for the odour of both healthy and infested chrysan-themum, while we found an opposite result in A. annua. Aphids tend to healthy plantscompared with the infested, and the phenomenon became obvious with time. Differentextracts were...
The growth of the A. coreopsidis population was positively affected by attending ants, showing greater increase on ant-present control plants than on ant-excluded plants. The density of aphids on control plants was positively correlated with the density of attending ants, while the density of ...
摘要: HS-SPME was used for volatile organic compounds collection.Combined with the GC–MS data and olfactometer bioassay results.Found two potential volatile compound to resist aphids.关键词:SPME GC–MS VOCs Aphid DOI: 10.1016/j.bse.2015.04.023 被引量: 2 ...
Plant-beneficial fungi play an important role in enhancing plant growth and protecting plants from biotic and abiotic stresses. However, context-dependency of such effects and differences among fungi often lead to inconsistent results that hamper their widespread use. Here, we investigated the effect ...
Effects of aphids Myzus persicae on the changes of Ca 2+ and H 2 O 2 flux and enzyme activities in tobacco 来自 掌桥科研 喜欢 0 阅读量: 117 作者:Ren,Wang,Chen,Liu 摘要: In order to understand the continuous defense reactions of host plants against insect attack, a tobacco variety ...
The effect of within-crop habitat manipulations on the conservation biological control of aphids in field-grown lettuce Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been ... DJ Skirvin,L Kravar-...
Decent and healthy growth of plants in soil is related to the soil medium's physical and chemical properties. Plants also display diverse defense reactions and growth curves against the insects that feed on their sap. In this study, vegetative growth parameters, chemical and physical content change...
