Rapid Divergence of Wing Volatile Profiles Between Subspecies of the Butterfly Pieris rapae (Lepidoptera: Pieridae)
Complex signaling traits such as pheromone profiles can play an important role in the early stages of reproductive isolation between populations. These signals can diverge along multiple trait axes, and signal receivers are often sensitive to subtle differences in signal properties. In the Lepidoptera, prior research has highlighted that natural selection can drive rapid chemical signal diverge...
متن کاملSexual dimorphism of short-wavelength photoreceptors in the small white butterfly, Pieris rapae crucivora.
The eyes of the female small white butterfly, Pieris rapae crucivora, are furnished with three classes of short-wavelength photoreceptors, with sensitivity peaks in the ultraviolet (UV) (lambda(max) = 360 nm), violet (V) (lambda(max) = 425 nm), and blue (B) (lambda(max) = 453 nm) wavelength range. Analyzing the spectral origin of the photoreceptors, we isolated three novel mRNAs encoding opsins...
متن کاملExperimental Evaluation of Arthropod Predation on Pieris rapae (Lepidoptera: Pieridae) Eggs and Larvae in Cabbage
Knowledge of factors causing mortality in herbivorous insects is essential to developing a better understanding of their population dynamics and more effective strategies to manage their abundance in crops. In this study we used 2 methods of predator exclusion to evaluate the effects of arthropod predators on Pieris rapae L. eggs and larvae on cabbages (Brassica oleracea variety capitata L.) in...
متن کاملDe Novo Assembly and Developmental Transcriptome Analysis of the Small White Butterfly Pieris rapae
The small white butterfly Pieris rapae is one of the most destructive pests of Brassicaceae. Yet little is understood about its genes involved in development. To facilitate research on P. rapae, we sequenced the transcriptome of P. rapae during six developmental stages, including the egg, three larval stages, the pupa, and the adult. In total, 240 million high-quality reads were obtained. De no...
متن کاملA spermatophore structured in the bursa copulatrix of the small white Pieris rapae (Lepidoptera, Pieridae) during copulation, and its sugar content
During copulation, the male small white, Pieris rapae, fills a single spermatophore in the bursa copulatrix of the female. The male fills first a white gel and then structures the spermatophore. The sperm was ejaculated last into the reproductive tract of the female, while sugars were observed throughout the copulation. Variation in size and sugar content of spermatophores observed in field-cap...
