白毫早茶园3种害虫与其捕食性天敌的数量、时间和空间关系

为了合理利用和保护天敌进行卵形短须螨、双斑长跗萤叶甲和假眼小绿叶蝉的综合防治,用灰色系统分析方法和生态位分析法对合肥地区白毫早茶园3种主要害虫与其捕食性天敌在数量、时间、空间等方面关系进行分析,利用害虫与天敌关系密切指数之和综合评判9种天敌与3种害虫关系密切的前四位天敌。2015年卵形短须螨的前四位天敌是鳞纹肖蛸(5.3079)、三突花蟹蛛(5.1716)、锥腹肖蛸(4.8367)和草间小黑蛛(4.7869);2016年前四位天敌依次是三突花蟹蛛(5.3975)、鳞纹肖蛸(4.9414)、茶色新圆蛛(4.8757)、锥腹肖蛸(4.6815)。对两年结果综合分析,卵形短须螨的前四位天敌依次是三突花蟹蛛(10.5691)、鳞纹肖蛸(10.2493)、茶色新圆蛛(9.6353)和锥腹肖蛸(9.5182)。2015年双斑长跗萤叶甲的前四位天敌依次是锥腹肖蛸(5.6926)、异色瓢虫(5.6976)、八斑球腹蛛(5.5101)和斜纹猫蛛(5.4552);2016年依次是茶色新圆蛛(5.2909)、锥腹肖蛸(5.2710)、鳞纹肖蛸(5.1063)和斜纹猫蛛(5.0703)。对两年结果综合评判,双斑长跗萤叶甲的前四位天敌是锥腹肖蛸(10.9636)、茶色新圆蛛(10.6578)、异色瓢虫(10.7580)和鳞纹肖蛸(10.5437)。2015年假眼小绿叶蝉的前四位天敌依次是锥腹肖蛸(5.3614)、粽管巢蛛(5.2259)、斜纹猫蛛(5.1300)和茶色新圆蛛(4.7472);2016年是锥腹肖蛸(5.2666)、粽管巢蛛(5.2561)、草间小黑蛛(4.9376)和斜纹猫蛛(4.8335)。对两年结果综合评判,假眼小绿叶蝉的前四位天敌依次是锥腹肖蛸(10.6280)、粽管巢蛛(10.4820)、斜纹猫蛛(9.9635)和茶色新圆蛛(8.6137)。该研究结果为白毫早茶园3种害虫防治时合理保护和利用自然界的天敌的种类提供了科学依据。

Relationship between the quantity, time, and space of three pests and their predatory natural enemies in Baihaozao Tea Garden

In order to rationally utilize and protect natural enemies, the comprehensive prevention and control of Brevipalpus obovatus Donnadieu, Monolepta hieroglyphica Mots, and Empoasca vitis Gothe,grey system and niche analysis were used to analyze the relationship between three main pests and their predatory natural enemies in quantity, time, and space. The sum of the close relationship between pests and natural enemies was used to comprehensively judge the first four natural enemies with close relationship between the nine natural enemies and the three pests.The first four natural enemies of the Brevipalpus obovatus in 2015 were Tetragnatha syusmata (5.3079), Misumenops tricuspidatu (5.1716), Tetragnatha maxillosa (4.8367), and Erigonidium graminicolum (4.7869). In 2016, there were Misumenops tricuspidatu (5.3975), Tetragnatha syusmata (4.9414), Neoscona theisi (4.8757), and Tetragnatha maxillosa (4.6815). For the comprehensive analysis of two-year results, the first four natural enemies of Brevipalpus obovatus were Misumenops tricuspidatu (10.5691), Tetragnatha syusmata (10.2493), Neoscona theisi (9.6353), and Tetragnatha maxillosa (9.5182). In 2015, the first four natural enemies of Monolepta hieroglyphica were Tetragnatha maxillosa (5.6926), Harmonia axyridis (5.6976), Theridion octmaculatum (5.5101), and Oxyopes sertatus (5.4552). In 2016, there were Neoscona theisi (5.2909), Tetragnatha maxillosa (5.2710), Tetragnatha syusmata (5.1063), and Oxyopes sertatus (5.0703). For the comprehensive evaluation of two-year results, the first four natural enemies of Monolepta hieroglyphica were Tetragnatha maxillosa (10.9636), Neoscona theisi (10.6578), Harmonia axyridis (10.7580), and Tetragnatha syusmata (10.5437). In 2015, the first four natural enemies of the Empoasca vitis were Tetragnatha maxillosa (5.3614), Clubiona japonicola (5.2259), Oxyopes sertatus (5.1300), and Neoscona theisi (4.7472). In 2016, there were Tetragnatha maxillosa (5.2666), Clubiona japonicola (5.2561), Erigonidium graminicolum (4.9376), and Oxyopes sertatus (4.8335). For the comprehensive evaluation of the two-year results, the first four natural enemies of the Empoasca vitis were Tetragnatha maxillosa (10.6280), Clubiona japonicola (10.4820), Oxyopes sertatus (9.9635), and Neoscona theisi (8.6137). The results provide a scientific basis for rational protection and utilization of natural enemies in the three pest control areas of Baihaozao Tea Garden.
