摘要:

Castrated male quails, exposed to long days (16L:8D), were implanted with 10 mm silastic capsules (internal diameter: 1,57 mm) containing testosterone or 5α-dihydrotestosterone (5α-DHT) or they were injected with estradiol benzoate (EB). The effects of these manipulations on cloacal gland growth, plasma levels of gonadotropins (FSH and LH), sexual behaviour and on testosterone metabolism in the brain and in the anterior pituitary were assessed. The cloacal gland size was much increased by testosterone and 5α-DHT and the conversion of testosterone to 5β-reduced metabolites in the pituitary was depressed by treatments with 5α-DHT and/or EB.

摘要:

Recent experimental research on ant species of theFormica rufa-group has shown signs of early olfactory learning in the ontogeny of cocoon nursing behaviour. On the contrary, similar research onLasius nigerL. has demonstrated that cocoon recognition and care are unrelated to early experience acquired by the young workers. This phenomenon appears to be due to the clear prevalence of innate components in the behaviour studied.
