Host plant resistance plays important roles in controlling pests and protecting of natural enemies in an agroecosystem, and the effect of insect resistant varieties in reducing damage is conspicuous. Fuzzy recognition technique evaluation were used to determine sources of resistance in wheat to populations of the wheat aphids in five field experiments over 2 years in wheat-producing areas of China. Results showed that the majority of wheat varieties identified were susceptible to aphids, and no immune and highly resistant varieties was observed. The mean percentage from the wheat varieties with resistant, lowly susceptible, moderately susceptible and highly susceptible to aphid were 9.30%, 23.15%, 42.32%, and 25.23% in whole wheat varieties respectively. 5 wheat varieties (Lantian18, Lantian20, Lantian22, Lantian00-30 and Shanmai175) were moderately resistant in Jiangyou in 2009, other resistant sources were low levels for aphid-resisant. And more importantly, 2 wheat varieties (Lantian20, Lantian22) with the continuous resistance to wheat aphid in the five experimental fields over 2 years were found. Although resistance of wheat varieties had a close relation to their genetics and inheritance, we also found that the evaluation result of the same wheat varieties were varied in different place. The results indicated that the resistance to aphid could be affected by geographical environment.These evaluations on reaction to aphid metapopulation that could be crucial when germplasm is used in crosses to improve wheat cultivars. This research is part of program to evaluate germplasm for useful traits and make this information available to the germplasm system. [less ▲]

The effects of intercropping of wheat cultivars and oilseed rape on the densities of wheat aphid, Sitobion avenae, and their arthropod natural enemies were evaluated. Three winter wheat cultivars with different resistant levels to S. avenae were used: `KOK¿ (high resistance), `Xiaobaidongmai¿ (low resistance) and`Hongmanghong¿ (susceptible). The results showed that the densities of S. avenae were significantly higher on the monoculture pattern than on either the 8-2 intercropping pattern (eight rows of wheat with two rows of oilseed rape) or the 8-4 intercropping pattern (eight rows of wheat with four rows of oilseed rape). The mean number of predators and the mummy rates of S. avenae were significantly higher in two intercropping patterns than those in the monoculture pattern. The densities of S. avenae, ladybeetles, and mummy rate of S. avenae were significantly different among different wheat cultivars. The highest densities of S. avenae and ladybeetles were found on wheat cultivar Hongmanghong. The lowest densities of S. avenae associated with high mummy rate of S. avenae were found on wheat cultivar Xiaobaidongmai. The results showed that wheat-oilseed rape intercropping conserved more predators and parasitoids than in wheat monoculture fields, and partial resistance of wheat cultivar Xiaobaidongmai had complementary or even synergistic effects on parasitoid of S. avenae.

To study the ecological regulation effects of species diversity in wheat fields on Sitobion avenae, field experiments were carried out in Langfang Experimental Station of Institute of Plant Protection, Chinese Academy of Agricultural Sciences from October of 2007 to July of 2008. The intercropping patterns of wheat and pea, by the proportion of planting row of pea and wheat in 2:2, 2:4, 2:6 and 2:8, were plotted, and the field cultivar monoculture of wheat was planted as the control. Population dynamics of apterae and alatae S. avenae, population dynamics, species richness, diversity index and evenness of main natural enemies were investigated systematically and analyzed. The results showed that, compared with monoculture of wheat, the amount of S. avenae apterae per 100 plants (square-root transformed) in aphid peak period were very significantly lower in the intercropping treatments (P<0.01), and the cascade was that wheat monoculture (77.38) > 2-2 intercropping (68.62) > 2-4 intercropping (68.51) > 2-8 intercropping (65.19) > 2-6 intercropping (64.94). Although population dynamics of main natural enemies showed a similar trend with time, wheat-pea intercropping could preserve and augment natural enemies more than monoculture of wheat, and there were higher population densities of ladybeetles and aphid parasitoids, and higher species richness and diversity index of natural enemies, but lower evenness index in each intercropping field. It is so concluded that wheat-pea intercropping system can not only reduce the population of S. avenae, but also improve the stability and sustainability of controlling wheat pests. [less ▲]

【Objective】 In order to research the effect of biodiversity on spatial distribution of Sitobion avenae in wheat, the population density of S. avenae was investigated in wheat fields in Langfang Experimental Station of Institute of Plant Protection, Chinese Academy of Agricultural Sciences, using wheat intercropped with pea by different patterns, and the field cultivar monoculture of wheat was planted as control.【Method】Using the Geographical Information System(GIS) and the traditional analysis methods of spatial distribution, the Kriging-interpolation figures, aggregation indices, Iwao and Taylor′s regression models were analyzed.【Result】The results showed that the spatial distribution of S. avenae was mainly aggregation distribution in intercropping patterns of wheat and pea, by the planting row of pea : wheat in 2︰2, 2︰4, 2︰6 ,2︰8 and wheat monoculture, but the degrees of aggregation were different, 2︰2 pattern > 2︰6 pattern > 2︰4 pattern > wheat monoculture > 2︰8 pattern. Kriging-interpolation figures indicated that wheat aphids distributed mainly around the field during early stage, and spreaded to the middle of field gradually. There were many aggregation centers mostly at wheat monoculture and 2︰2patterns plots during aphid peak period. Compared with each intercropping field, there were higher population densities of aphid in field cultivar monocultures at the level of P<0.01.【Conclusion】Although the reasonable biodiversity in wheat fields could control the population of wheat aphid effectively, the spatial distribution did not change.

To study the ecological effect of genetic diversity in wheat field on Sitobion avenae. the population dynamic of S. avenae and it’s natural enemies was investigated systematically in wheat fields, the spatial distribution of S. avenae.was also analyzed.The results showed that, compared with monocultures, cv. Beijing 837, the amount of S. avenae apterae per 100 plants in intercropping pattern were significantly lower during aphid peak period, and the cascade of population densities was that cv. Beijing 837 monoculture(7422.0) > intercropped with cv. KOK(5796.7) > intercropped with cv. Hongmanghong(5406.7) > intercropped with cv. Zhengzhou831(5291.7) > intercropped with cv. JP2(4493.4) > intercropped with cv. Zhongsiwumang(4155.0),,and the spatial distribution of S. avenae were changed from aggregated pattern to uniform one. In aphid parasitoids peak period, there were higher population densities of aphid parasitoids in each intercropping field with the very significant level of P<0.01. The theoretical yield were more increasing with the significant level of P<0.05. Above all, the intercropping of wheat varieties of different resistance to aphids with the field cultivar could own an obvious advantage in ecological regulation to S. avenae. [less ▲]
