This study discusses about language use occurred by male and female host in Hitam Putih talk show. The method of this research is descriptive qualitative. The subjects of this study are male and female host in Hitam Putih talk show. The data are the utterances produced by male and female host in Hitam Putih talk show. This research focuses on the show broadcasted on October 2016 by taking 4 videos randomly. The objective of this study is to describe kinds of the language use uttered by male and female host in Hitam Putih talk show. The findings showed that the kinds of language use consist of 6 parts. The dominant language use uttered by male host is expletive, because male’s utterances are frequently stated in a negative connotation. On the other hand, female host utterances are found in specialized vocabulary as the most dominant because female host has more interest in talking family affairs, such as the education of children, clothes, cooking, and fashion, etc. Women also tended to talk about one thing related to the home and domestic activities. However, the representation of language use uttered by male and female are deficit, dominance and different. Keywords: Language Use, Gender, Talk Show

Sexual dimorphism is recorded among the puparia of six species of Aleurocanthus from Taiwan, including Aleurocanthuslauriphaga sp.n. from Cinnamomum osmophloeum. A key is provided to the puparia of seven species of this genus knownfrom Taiwan, with illustrations of immature stages and the adult male and female of the new species. The flocculent waxsecretion pattern in the puparia of this new species is atypical amongst Aleurocanthus species. Newly recorded from Tai-wan is A. citriperdus Quaintance & Baker, and the record of A. spinosus (Kuwana) from Taiwan is discussed. A list of recorded host plants of Aleurocanthus species from Taiwan is provided.

Inbreeding can profoundly affect the interactions of plants with herbivores as well as with the natural enemies of the herbivores. We studied how plant inbreeding affects herbivore oviposition preference, and whether inbreeding of both plants and herbivores alters the probability of predation or parasitism of herbivore eggs. In a laboratory preference test with the specialist herbivore moth Abrostola asclepiadis and inbred and outbred Vincetoxicum hirundinaria plants, we discovered that herbivores preferred to oviposit on outbred plants. A field experiment with inbred and outbred plants that bore inbred or outbred herbivore eggs revealed that the eggs of the outbred herbivores were more likely to be lost by predation, parasitism or plant hypersensitive responses than inbred eggs. This difference did not lead to differences in the realized fecundity as the number of hatched larvae did not differ between inbred and outbred herbivores. Thus, the strength of inbreeding depression in herbivores decreases when their natural enemies are involved. Plant inbreeding did not alter the attraction of natural enemies of the eggs. We conclude that inbreeding can significantly alter the interactions of plants and herbivores at different life-history stages, and that some of these alterations are mediated by the natural enemies of the herbivores.

Based on morphological characters and host plant use, species related to Schinia chrysellus (Grote) are revised. Schinia alencis (Harvey) is considered a valid species, revised status. Schinia chrysel- loides, new species is closely allied with S. chrysellus, and Schinia rufocostulata, new species is related to S. ciliata Smith. Localities of collected adult moths and their asteraceous host plants are compared and illustrated with distribution maps. Adults and male and female genitalia are illustrated for each species.

AbstractGreen leaf volatiles (GLVs) have been reported to play an important role in the host-locating behavior of several folivores that feed on angiosperms. However, next to nothing is known about how the green leafhopper, Empoasca vitis, chooses suitable host plants and whether it detects differing emission levels of GLV components among genetically different tea varieties. Here we found that the constitutive transcript level of the tea hydroperoxide lyase (HPL) gene CsiHPL1, and the amounts of (Z)-3-hexenyl acetate and of total GLV components are significantly higher in tea varieties that are susceptible to E. vitis (Enbiao (EB) and Banzhuyuan (BZY)) than in varieties that are resistant to E. vitis (Changxingzisun (CX) and Juyan (JY)). Moreover, the results of a Y-tube olfactometer bioassay and an oviposition preference assay suggest that (Z)-3-hexenyl acetate and (Z)-3-hexenol offer host and oviposition cues for E. vitis female adults. Taken together, the two GLV components, (Z)-3-hexenol and especially (Z)-3-hexenyl acetate, provide a plausible mechanism by which tea green leafhoppers distinguish among resistant and susceptible varieties. Future research should be carried out to obtain the threshold of the above indices and then assess their reasonableness. The development of practical detection indices would greatly improve our ability to screen and develop tea varieties that are resistant to E. vitis.

Rabbit Spermatozoa

SUMMARY The capacity of rabbit spermatozoa to penetrate the zona pellucida of the ovum has been reported to depend upon pre-conditioning within the reproductive tract of the oestrous female. The present experiments show that spermatozoa can be capacitated in the uteri and uterine tubes of rabbits ovariectomized 1 month previously, in the isolated colon or bladder of male and female host rabbits, and in the anterior chamber of the eye and glandula vesicularis of male hosts. Spermatozoa were partially capacitated when they were confined within the excised uterine horns of a rabbit, and when they were suspended with strips of endometrium in saline solution at room temperature. Capacitation was not obtained when spermatozoa were confined in a cellophane dialysis bag within the intact uterus of an oestrous host, in the excised uterus of a sheep, or when they were suspended in saline with red blood cells or with dead spermatozoa.
