论文代写-蚜虫诱导植物化学痕迹的实验分析

论文代写-蚜虫诱导植物化学痕迹的实验分析。根据之前的实验，我们能够对有无防御虫的蚜虫诱导的植物化学痕迹做出反应。前期的实验结果表明，防御蚜诱导的植株能吸引A.ervi。比蚜虫诱导的植物还多。X (5 VS 10)表示我使用了5个共生带菌蚜虫诱导的植株，共10个共生带菌蚜虫诱导的植株中有50个共生带菌蚜虫(组1)，10个共生带菌蚜虫诱导的植株中有10个共生带菌蚜虫，共10个共生带菌蚜虫诱导的植株中有100个共生带菌蚜虫(组2)。每对中有一株来自第一组和第二组。这两种植物将放在嗅觉仪的两侧。10只不共生蚜虫作为对照组，唯一变化的是共生诱导密度。

The underlying indication is that the response to synomones induced in herbivore by parasitoids is specific to the host. Heimpel and Kris (2007) had been seen recording responses of experienced and naïve Gahan (Binodoxys communis) females to the odours from both non- target and target complexes of plant. This is done by the use of Y-tube assays of olfactometer. It was indicated in the study that females of B. communis tend to respond to a broad range of olfactory stimuli, exhibiting low level of fidelity for any specific odor. Also, there is an employment of some plasticity of behaviour in responding to the cues of volatility.
Once the parasitoid ends up reaching a potential habitat of host, it starts searching for the host near or over the host plant. The females tend to be responding to visual, chemical and physical stimuli in association with the hosts prior to encountering the host itself. Majority of the chemical stimuli seem to be acting in the form of kairomones, under production of the host itself or to arise as a result of the host products. These kairomones are known to be either non- volatile, perceived by olfaction or volatile kairomones of contact. This means X2 = 14.60, d.f. = 1, P < 0.05, in which females of A. colemani showed more frequent oriented flights in comparison with the females of L. testaceipes species. From the other perspective, both the species showed more preference for the actual plants instead of dummy plants, as a result of which, X2 = 0.67, d.f. = 1, ns. Both the species were known to be showing the same rate of landing on both, uninfested plants and infested plants. In the tunnel of wind, both the species were known to be showing different responses of behaviour that are highly dependent on the fact that is they were in phases of landing, flight or pre- flight.
In the overall context, 89.3 per cent of the females were known to show the behaviour of flight in the tunnel of wind. Out of the females showing behaviour of flying, the share that performed a flight in orientation had been significantly greater in comparison with the share which did not. According to the analysis, the share was 64.2 per cent vs. 35.8 per cent, and hence, X2 = 8.99, d.f. = 1, P< 0.05. Among the females performing an oriented response of flight, a significant variation had been found in the location of landing between the real plants and dummy.
