This is also true for karpophagic and parasitic insects. The selection of specific chemical conditions could be either inherited or acquired. If learned information determines host selection, we have a case of imprinting, as a) reception and use of the information are not simultaneous, b) there is no reward. In experiments with Drosophila melanogaster we marked the egg deposition medium with ethanol, acetic acid, peppermint oil, or benzaldehyd. The flies spontaneously prefer mediums with ethanol and acetic acid, and reject peppermint oil and benzaldehyd. If they are reared in one of these media, the preference for it is increased, or the rejection rate lowered. Rearing with actinomycin C neutralizes the effect of the other markers. It is concluded that actinomycin C blocks imprinting on the egg deposition substrate in Drosophila melanogaster.</p>","PeriodicalId":76861,"journal":{"name":"Zeitschrift fur Tierpsychologie","volume":"44 2","pages":"113-29"},"PeriodicalIF":0.0,"publicationDate":"1977-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11293592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The kids showed a clear preference for play on sloped terrain, even though this choice resulted in considerably greater risks. The danger involved in highly active locomotor play performed on steeply sloped areas is presumably outweighed by the physical training benefit for an adult life spent moving in precipitious areas.","PeriodicalId":76861,"journal":{"name":"Zeitschrift fur Tierpsychologie","volume":"42 1","pages":"199-209"},"PeriodicalIF":0.0,"publicationDate":"1977-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75276354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental evidence indicates that the volatile female sex pheromone of each species is attractive to males of most of the other species. Rejection of heterospecific males appears to be due to species specific male pheromones. These pheromones also appear to mediate the formation of homospecific clusters of courting males in time or space.","PeriodicalId":76861,"journal":{"name":"Zeitschrift fur Tierpsychologie","volume":"29 1","pages":"85-103"},"PeriodicalIF":0.0,"publicationDate":"1977-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88348097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
