| 1 | 30%茶皂素AS防治甘蓝菜青虫田间药效试验显示文摘菜青虫是十字花科蔬菜上危害严重的一种常见虫害,严重影响蔬菜的产量和品质。为掌握30%茶皂素AS对菜青虫的防治效果,笔者以咸安地区种植较广的甘蓝开展田间药效试验,为植物源制剂的推广应用、大力推行绿色防控和贯彻'绿色植保'理念提供依据。1材料和方法1.1试验对象和试验作物防治对象:菜青虫(Pieris rapae Linne)供试作物:甘蓝('松花90')1.2试验田试验在咸安区双溪桥镇杨堡村进行。 | 陈充 徐振强 徐丹 廖波 | 2016 | 湖北植保2016，，2： | 4 |
| 2 | Grayanane Diterpenoids from Pieris formosa显示文摘Three grayanane diterpenoids 1-3 were isolated from Pierisfonnosa. 1 was identifiedas a new natural product and 2 and 3 as known grayanoside C and grayanotoxin XVIII on the basisof spectral analysis. | Wang, LQ Ding, BY Zhao, WM Qin, GW | 1998 | Chinese Chemical Letters1998，9，5： | 3 |
| 3 | A Method for Preparing Insecticide of Cabbage Worm Pieris rapae and Its Control Effects显示文摘[Objective]The paper was to study the field control effects of different formulae of plant extracts against cabbage worm Pieris rapae,and to provide a basis for promotion and application of insecticides in production.[Method]With the leaching solution of radix anemones rivularis,Artemisia carvifolia and Nicotiana rustica,and lime and salt water as the materials,field efficacy test was conducted for consecutive two years.[Method]When the mass ratios of radix anemones rivularis mother liquid,A.carvifolia mother liquid,N.rustica mother liquid,lime water and salt water were 4:2:2:1:1:6,4:2:0:1:1:8,4:0:2:1:1:8 and 0:4:2:1:1:8,the control effects were 82.7%-89.8%,38.3%-42.0%,41.0%-45.4%and 52.9%-56.4%,respectively.The insecticide showed the best control effect when the mass ratio of radix anemones rivularis mother liquid,A.carvifolia mother liquid,N.rustica mother liquid,lime water and salt water was 4:2:2:1:1:6.[Conclusion]The optimal formula has good control effect against P.rapae,and the technology has obtained national invention patent. | Xu Xuezhong Hu Jingfeng Yang Hongli Zhang Liqin Lan Mei Liu Jiajia He Jiangming Cai Rongjing Zhu Shiyin Tu Guojing Yang Jingkang Liu Xianmei | 2019 | Plant Diseases and Pests2019，10，4： | 0 |
| 4 | 菜粉蝶越冬新情况的调查初报显示文摘菜粉蝶 Pieris rapae(Linnaeus)是我国十字花科蔬菜的重要害虫之一。近几年来,我们在预测预报中发现其越冬情况有了新的变化。为便于今后的预测预报工作,我们对其越冬虫态及越冬场所进行了调查分析.材料和方法1.1984年开始,每年年初在菜粉蝶越冬蛹羽化之前(1月),对我所座落在菜田中的一段围墙上的菜粉蝶越冬蛹进行调查。该段围墙长100米,高2米,东西向建筑,调查南北两侧各自的越冬蛹数量,并采回室内观察羽化情况。每年1、2月间。 | 尹仁国 | 1991 | 病虫测报1991，20，3： | 0 |
| 5 | Field Efficacy Trials of Different Pesticides against Pieris rapae and Plutella xylostella显示文摘Field efficacy trials of different pesticides against Pieris rapae and Plutella xylostella showed that seven pesticides had certain control effects against P.rapae and P. xylostella. 240 g/L Chlorfenapyr SC had the most ideal control effect,with quick effect and long persistence,and the control effects against P. rapae and P. xylostella were 91. 96% and 95. 73% after application for 7 d,respectively. 25% Thiamethoxam WDG 3 000 times dilution had the poorest control effect,and quick effect and persistence were not ideal; the control effects against P. rapae and P. xylostella were 49. 21% and 57. 20% after application for 7 d,respectively. The remaining pesticides had good control effect against both P. rapae and P. xylostella,with certain persistence. Slight injury such as yellowing tender leaves appeared in the area treated with 50% thiocyclam SP,although the injury was reversible,it was still not recommended to use; no other treatments had adverse effects on growth of cabbage. | Zhao Li Hong Wenying Wu Yanjun Wang Yanxin Chen Rui Zhang Linying | 2014 | Plant Diseases and Pests2014，5，2： | 0 |

| 7 | Mobility affects copulation and oviposition dynamics in Pieris brassicae in seminatural cages显示文摘When, how often and for how long organisms mate can have strong consequences for individual fitness and are crucial aspects of evolutionary ecology. Such determinants are likely to be of even greater importance in monandrous species and species with short adult life stages. Previous work suggests that mobility, a key dispersal? related trait, may affect the dynamics of copulations, but few studies have investigated the impact of individual mobility on mating latency, copulation duration and oviposition latency simultaneously. In this paper, we monitored the copulation dynamics of 40 males and 40 females, as well as the oviposition dynamics of the females of the Large White butterfly Pieris brassicae, a facultative long-distance disperser butterfly. Individuals from a breeding were selected to create a uniform distribution of mobility and we recorded the timing, number and duration of all copulations in a semiexperimental system. We showed that mobility, measured as the time spent in flight under stressful conditions (a proxy of dispersal tendency), correlates with all aspects of copulation dynamics: mobile males and females mated earlier and for shorter periods than less mobile individuals. In turn, late mating females increased the time between copulation and oviposition. These results feed the previously described mobility syndrome of R brassicae, involving morphological and physiological characters, with life-history traits. We suggest that the reduction of mating latency and copulation duration has an adaptive value in dispersing individuals, as their life expectancy might be shorter than that of sedentary individuals. | Nicolas Larranaga Michel Baguette Olivier Calvez Delphine Legrand | 2019 | Insect Science2019，26，4： | 0 |
