Vibrational directionality in the southern green stink bug, Nezara viridula (L.), is mediated by female song
Article Abstract:
It has been possible to produce the first direct evidence that vibrational directionality is used during mating behaviour in insects and that this phenomenon is sex specific. Research in this area tested the hypothesis that male southern green stink bugs, Nezara viridula (L.), use substrate-borne songs to locate females. The fact that the directionality response was shown only in males corresponds with observations on a plant where females were not seen to approach the singing male. There is still uncertainty about the precise mechanism underlying vibrational directionality in the southern green stink bug, but spatial differences in timing and amplitude may be used.

Effects of sexually transmitted diseases on heritable variation in sexually selected systems
Article Abstract:
Individuals who are able to find mates easily are more susceptible to sexually transmitted diseases (STD). Suitable selection of mates helps in maintaining heritable genetic characteristics related with male traits and female choice. Alteration in fitness of particular genotype regulate heritable genetic variations. STD-causing organisms are transmitted only during copulation, hence STD induces high selection against the opted male. Non-random selection may inhibit induction of specific male traits in the absence of host resistance.

Female canaries are sexually responsive to special song phrases
Article Abstract:
Sexual sensitivity of female canaries, Serinus canaria, is influenced by early experience or 'sensory bias'. The study shows that female canaries are especially responsive to certain short phrases whose important features are short silences and abrupt frequency fall. This differential responsiveness took place regardless of the serial position of the phrase in songs and its relationship to other different conspecific phrases and the general song context.
