ABSTRACT
The transparent wings of most of the tiny insects display surprising structural colouration, known as wing interference patterns (WIPs). The concept of wing interference colours (WICs) was recently introduced to the quantification of WIPs. Oomyzus sokolowskii is a potential biological control agent for the diamondback moth (DBM), Plutella xylostella (L.) (Lep.: Plutellidae) on Brassica spp. Investigation of the WIPS and WICs of two populations indicates that despite slight intra-species variations in colours and pattern shape and also both sexes, this variation was not significant. WICs do not present any sexual dimorphism but, in the side-by-side comparison, the marginal yellow spot was much clearer in females and it may be used as a visual cue for sexual attractiveness.
