  larviposition
Water strain in the host plant reduced aphid feeding and larviposition and sometimes increased the proportion of winged offspring.
      
was sufficient to reduce substantially the settling, larviposition and survival of A.
      
Decapitation of adult aphids released the larviposition response and also resulted in prenatal diversion of their progeny.
      
The factors affecting host finding and larviposition of the adult females were evaluated.
      
This would not have occurred or have been as marked if seedling hostplants (radish or mustard) had been used as larviposition and larval rearing substrates.

Adults of Dermacentor collected from different geographical areas were reared it the laboratory and a large number of larvae thus obtained were analyzed according tt their morphological characters. The results revealed that the larvae varied very greatly in this respect and the intraspecific variations of the same species collected from different geographical areas or obtained from different females may be even greater than the interspecific variations.

Adults of Dermacentor collected from different geographical areas were reared it the laboratory and a large number of larvae thus obtained were analyzed according tt their morphological characters. The results revealed that the larvae varied very greatly in this respect and the intraspecific variations of the same species collected from different geographical areas or obtained from different females may be even greater than the interspecific variations. Therefore, the described morphological characters and pxt-blished identification key of the larvae of these species based on a small number of specimens may be of limited use or not correct. After analyzing the data from larger number of specimens the author has found more stable morphological characters for the identification of two species in this genus, i.e., the width of capitulum and the length of scutum which can be used to distinguish between D. nuttalU and D. silvarum. These two species can be separated from other three species of Dermacentor distributed in North China (i.e., D. marginatus, D. niveus and D. reticulatus) by the length of scapular setae (Sc) and first central dorsal setae (Cd1).Key to five common species of larvae of Dermacentor in Palaeoarctic region:1. The length of Sc usually more than 32 μ, the length of Cdi more than 27 μ................................................................................................... 2The length of Sc usually less than 32 μ, the length of Cd1 usually less than 27 μ... 42. Dorsal surface of the palp with a long seta, without conical sensillum. Auricles obvious, located far away from the posterolateral margins of the basis capituli............ D. reticulatus (Fabricius) Dorsal surface of the palp with a long setaand a conical sensillum. Auricles not obvious, located near the posterolateral marginsof the basis capituli ................................................... 33. The width of eapitulum more than 172 μ, the length of palp usually more than117 μ............................................................... D. marginatus SulzerThe width of capitulum less than 172 μ, the length of palp usually less than 117 μ ........................................................................... D. niveus Neumann4. The width of capitulum more than 185 μ, the length of scutum usually morethan 265 μ..................................................... D. silvarum OlenevThe width of capitulum less than 185 μ., the length of scutum usually less than 265 μ ........................................................................... D. nuttalU Oleney

将采自不同地区的草原革蜱Dermucentor nuttalli Olenev和森林革蜱Dermaeentor silvarum Olenev成虫在实验室中培养,对所获幼虫的形态特征用生物统计方法进行分析。结果证明,革蜱幼虫的一些形态变异很大,同一种革蜱采自不同地区或不同雌虫所产的幼虫的个体变异甚至比种间变异还大。所以,前人根据个别地区少量材料所描述的上述幼虫形态特征及所做的检索表,不能广泛适用。作者分析了大量材料后,找出上述两种幼虫较稳定的鉴别特征。根据假头宽和盾板长可以区分草原革蜱和森林革蜱;按照肩毛(Sc)和第一对背中毛(Cd_1)的长度可以把上述两种幼虫与我国北部分布的其他三种革蜱(边缘革蜱、银盾革蜱和网纹革蜱)区别开来。

Several factors influencing the larviposition of adult trichinella spiralis in vitro and in vivo were studied. In the different experimental animal hosts, the fecundities of adult worms were different. In the rats, the jirds and mice, the adult worms recovered from the small intestine of the rats deposited the most larvae and those recovered from the small intestine of the mice shed the least larvae (P<0.01). Adult worms recovered from the small intestine of the female rats deposited fewer larvae than those...

Several factors influencing the larviposition of adult trichinella spiralis in vitro and in vivo were studied. In the different experimental animal hosts, the fecundities of adult worms were different. In the rats, the jirds and mice, the adult worms recovered from the small intestine of the rats deposited the most larvae and those recovered from the small intestine of the mice shed the least larvae (P<0.01). Adult worms recovered from the small intestine of the female rats deposited fewer larvae than those isolated from the small intestine of the male rats (p<0.01).Adult worms isolated from the anterior half of the small intestine of the rats produced more larvae than those recovered from the posterior half of the small intestine of the rats (p<0. 01). As the level of infection in rats increased, the number of newborn larvae shed in vitro by adult worms decreased. The 7-day old adult worms (post-infection) deposited more larvae than did those of younger or elder than 7-day old worms (P<0.01). In the complete incubation solution of M-199 or RPMI-1640,the number of newborn larvae shed by adult worms was similar. and more than those shed by adult worms incubated in the complete incubation solution of BME,MEM or Hank's fluids (p<0.01). Adult worms incubated at temperature above and below 37℃ (42, 40, 35, 30, 25℃)shed fewer larvae than those incubated at 37℃(p<0.01). The mean number of newborn larvae shed in vitro by adult worms was independent of the number of female worms (20,40,80,160)present in equal volumes of incubation solution. Adult female worms deposited similar number of newborn larvae in virto in the presence and in the absence of adult male worms in the incubation solution.

实验动物不同对旋毛虫产幼虫数有影响,从大鼠小肠收集的成虫产虫数较长爪沙鼠和小鼠的明显为多;自雄性大鼠小肠所收集的成虫其产虫数较雌性大鼠的屈著为多;自大鼠小肠前半部所收集的成虫产虫数较小肠后半部者的著为多。感染大鼠的肌肉期幼虫用量对成虫的产虫数有影响,感染量越多,平均每条成虫产幼虫数越少。7日龄成虫其产虫数较5、9、11日龄的显著为多;在M—199或RPMT—1640完全培养液中成虫产虫数较在BME、MEM或Hank′s完全培养液中显著为多;37℃时培养的成虫其产虫数较25、30、35、40、42℃培养的显著为多。在20~160条/3ml培养液范围内成虫数不受培养密度的影响,在培养液中雌虫的产虫数不受雄虫存在与否的影响。

The life history of Eulaclaps stabularis includes five stages: ovum, larva, protonymph. detonymph am: adult. However, oviposition is very rare with no vitality, so the mites arc ovoviviparous. and produce larva or protonympb. The conManlly accumulating cffective tempterature and the developmental zero of the stager are as follows: larva, 11.53 day-dicree and 6.27; proionymph, 38.87 day-degree and 9.36; deulonymph, 48.14 day-decree and 7.92. The proper temperature point may lie in between 20-25.

厩真厉螨的生活史分五期:卵、幼虫、一期若虫、二期若虫和成虫。产卵极少且无生活力,以卵胎生为主,产幼虫或一期若虫。整个成虫期均有交配行为,未见孤雌生殖。该螨幼虫期有效积温常数11.53日度,发育起点6.27℃;一期若虫有效积温常数38.87日度,发育起点9.36℃;二期若虫有效积温常数48.14日度,发育起点7.92℃。最适温度在20—25℃间。
