Abstract: | Experiments dealing with the role of juvenile hormone, adipokinetic hormone and diuretic hormone in the Painted Lady butterfly Vanessa cardui are reported. The results demonstrate an important role of JH in the regulation of ovarian and colleterial gland development in females, and in the regulation of accessory gland, tubular gland and ejaculatory duct development in males. In addition, the presence of an adult reproductive diapause, characterized by decreased effective juvenile hormone haemolymph titres, is suggested. Evidence for the existence of both adipokinetic and diuretic hormones in the Painted Lady is also presented, as is data indicating that both hormones may be similar or identical to those previously described in Monarch butterflies. Owing to the above results, and the existence of an artificial diet suitable for mass rearing in the laboratory, the Painted Lady appears to be an excellent species for studies on adult lepidopteran neuroendocrinology. |
