为研究交配对扶桑绵粉蚧雌虫发育及产卵的影响,比较了不同交配条件下扶桑绵粉蚧雌虫的寿命、产卵习性和产卵量。结果表明,交配对扶桑绵粉蚧雌虫的卵巢发育和产卵有促进作用。与延迟交配的扶桑绵粉蚧相比,正常交配的扶桑绵粉蚧雌虫卵巢内总产卵量、孕卵期、产卵期和首次产卵量均显著提高;而未经交配的雌虫体内的卵细胞不能受精。延迟交配的雌虫可以通过对营养的重新分配延长自身寿命,一旦发生交配,体内生理发生重导向可再次产卵,产卵量显著低于正常交配雌虫
To study the effects of mating status on development and oviposition in female mealybugs, Phenacoccus so-lenopsis.We compared the longevity, ovarian development and number of eggs laid in Phenacoccus solenopsis under different mating status.The results showed that in Phenacoccus solenopsis, mating stimulated ovarian development and oviposition.Mated Phenacoccus solenopsis females had higher total number of eggs laid, duration of gestation, duration of reproduction and number of eggs laid in the first clutch compared to delay-mated females.When grown into oviposi-tion period, unmated females could not develop into the embryonic phase and laid few eggs.Delay-mated females could make a trade-off between maintenance and reproduction by a nutritional rearrangement, which indicated that females would resorb the resources from eggs for a longer survival when they couldn''t get mated.Once mated, females would lay eggs, and their physiological state got reset, but the number of eggs l

在3个不同水稻品种上,研究江西南昌晚稻田内两索线对不同翅型和性别褐飞虱的寄生能力。结果表明:在同一水稻品种上,两索线对不同类型褐飞虱的寄生率之间存在显著差异,其寄生率的大小顺序为:短翅型雌虫>长翅型雌虫>短翅型雄>长翅型雄。其中,在短翅型雌虫体内,最高寄生率达45.16%;而在长翅型雄体内,最低寄生率仅为2.15%。在水稻品种株两优120上,两索线对短翅型雌虫的寄生数量达3头的占9.68%,对短翅型雌虫和长翅型雌虫寄生有2头的分别占6.45%和8.33%;在丰华占和合美(丰)上,对短翅型雌虫寄生数量最多为2头,寄生率分别为5.25%和4.35%;对不同类型褐飞虱的寄生数量为1头的均较高。可见,两索线对田间褐飞虱种群具有较强的寄生能力,可有效抑制褐飞虱的发生与危害。
The parasitic capacities of Amphimermis sp. to Nilaparavata lumens (Stal) were investigated into three kinds of rice varieties planted in Nanchang, Jiangxi Province. The results showed that the parasitic rates of different wing types and genders of N. lumens had significant difference at each rice variety, and that the order of the parasitic rates showed as follows:brachypterous females (BF)>macropterous females (MF)>brachypterous males (BM) > macropterous males (MM). Among them, the highest parasitic rate of BF was 45.16%, but the lowest parasitic rate of MM was only 2.15%. The parasitic rate of BF with 3 nematodes in body was 9.68%, and those of BF and MF with 2 nematodes were 6.45%and 8.33%, respectively, at the rice variety Zhuliangyou 120, but the parasitic rates of BF with 2 nematodes were 5.25%and 4.35%at the rice varieties Feng hua zhan and He mei zhan, respectively. Generally, the parasitic rate with just l nematode was higher than that with 2 or 3 nematodes. All the data abov

[目的]尽管一多雄在瓢科中常见,但各研究中获得的数据不足以解释雌虫多次交配和一多雄的一般适应性意义或适合度后果.本研究以温度为胁迫因子,旨在评价一多雄的某些益处(如增加的适合度)是否可传递给后代.[方法]本研究检测了黄斑盘瓢Coelophora saucia(Mulsant)3种交配处理中的适合度:一一雄(与同一雄交配5次,1次/d),先后一多雄(与5头不同的雄依次交配5次,即每天与新的雄交配1次),以及同时一多雄(放进5头雄,任由雌虫选择雄,交配5次,1次/d).观察了各交配处理不同温度下(25,27和30℃)繁殖力、卵的育性、后代发育和存活.[结果]结果表明,经历一多雄然后进行交配选择或竞争的性的繁殖能力最强,后代能在更广温度范围内最好地适应发育和存活.但先后一多雄交配的性与一一雄交配的性的繁殖能力相似.[结论]结果说明,在无交配选择或雄性竞争的条件下,一多雄的益处不明显.这可能是由于在依次射精的雄性间存在精子竞争,或由于性的隐性选择.据我们所知,本研究中观察发现的无交配选择时不表现一多雄的益处的现象,之前在昆中未观察到过.
[Aim] Although polyandry is common among Coccinellidae,the data attained in various studies are insufficient to explain the general adaptive significance (or fitness consequences) of female remating and polyandry.Temperature was used as a stressor in the study.This study aims to evaluate whether certain benefits of polyandry in terms of increased fitness are also passed on to the progeny.[Methods] The present study examined the fitness consequences of three mating treatments in Coelophora saucia (Mulsant) (Coleoptera:Coccinellidae):monandry (five matings with same male; one mating/ day),sequential polyandry (five matings with five different males with one mating/day with a new male),and simultaneous polyandry (five matings with five males introduced together allowing female to select male to mate; one mating/day).Changes in fecundity and egg fertility,and offspring development and survival of the different mating treatments under different temperatures (25,27 and 30℃) were o

微孢子是母蛾检疫的唯一对象,为探明家蚕微孢子感染雄蛾交配对蛾的影响,了解其对蚕种生产的危害性,用患微粒子病的家蚕雄蛾与未患病蛾(各50只)进行交配试验,并统计分析交配后的感染率。结果表明:患有家蚕微孢子的雄蛾,能通过雄蛾交配把微孢子传给蛾,蛾微孢子检出率为66%,其交配传染率达78.57%,增加了各级蚕种因母蛾检测有微孢子而淘汰的风险系数。因此,蚕种生产过程中防微病工作很重要,必须贯彻预防为主、综合防治的方针,切断幼期食下感染的途径,减少因雄蛾感病通过交配而传给蛾的概率,减少蚕种损失。
Micropsoridia is the only target on the quarantine of female silkworm moth.In order to clarify the influence of microsporidium on the female silkworm moth after mating of the female and male silkworm,and understand the harmfulness of silkworm egg production.The authors conducted mating test of infected male silkworm moth and uninfected female silkworm moth.And the infection rate was analyzed after mating.The result indicated that the microsporidian spores,N .bombycis,can be transmitted from infected male silkworm moth to uninfected female silkworm moth by mating.The detection rate and mating infection rate reached 66% and 78.57% respectively,and increased the elimination rate of silkworm eggs because of the Pebrine mother moth.So,the work of prevention to pebrine is very important in the process of the silkworm eggs production.The principle of prevention first,comprehensive control must be executed.In order to cut off the way of food transmission of infection,reduce the infec
