花粉粘虫板对西花蓟马诱集效果的研究

摘要

In order to develop the development and application of sticky cards, pollen sticky cards were used to trap western flower thrips Frankliniella occidentalis in red rose plastic greenhouses in Kunyang County. Complete random split block design was used to set the pollen sticky cards experiment by using five kinds of common pollen, that is rose pollen, rape pollen, camellia pollen, peach pollen and pinus pollen, with different five concentration, that is 0.05 g/plate, 0.15 g/plate, 0.3 g/plate, 0.5 g/plate, 0.75 g/plate. After two continuous red rose growing seasons in 2016, the results showed that there was no significant difference in trapping effect on western flower thrips among five kinds of pollens, but there is extremely significant difference in trapping effect among five different concentrations. And with the increase of concentration, the trapping effect was rising firstly, arriving the best trapping effect at 0.30 g/card, then reducing. There was significant difference in the interaction effect of concentration and pollen. The sticky card with 0.15 g rape pollen and 0.30 g camellia pollen had two best trapping effect. The average amount of former trapping is 57.44 per plate. The average amount of latter trapping is 51.00 per plate. And there also had extremely significant difference among different trapping time in the red rose growing season. The trapping effect was the best at the beginning of the flower season. Therefore, the pollen sticky cards can trap the western flower thrips efficiently with 0.15 or 0.30 concentration.%为了进一步开展高效粘虫板的研发与应用,本实验选用5种常见花粉(即玫瑰、油菜、茶花、桃花和松花花粉)并分别配比5种不同浓度(即0.05 g/板、0.15 g/板、0.30 g/板、0.50 g/板、0.75 g/板)制成花粉粘虫板,采用完全随机裂区设计方法,在昆阳镇塑料大棚内红色切花月季上进行西花蓟马诱集实验.2016年连续调查2个红色切花月季的生长周期,结果表明:不同花粉的诱集效果间无显著性差异;不同浓度的诱集效果间差异极显著,且随着花粉处理浓度升高诱集效果先升高后降低,0.30 g/板时花粉粘虫板的诱集效果最好;花粉与浓度之间也存在极显著的交互效应,浓度为0.15 g/板的油菜花粉粘虫板(平均诱集量为57.44头/板)和浓度为0.30 g/板的茶花花粉粘虫板(平均诱集量为51.00头/板)对西花蓟马的诱集效果最好;红色切花月季不同时间的诱集效果间也存在极显著性差异,且随着诱集时间延长,花粉粘虫板对西花蓟马的诱集效果呈下降趋势,至末花期诱集效果又开始有所回升.总之,花粉粘虫板对切花月季上的西花蓟马有显著的诱集效果.
