An improved rearing technique is described for P. callosus. It involves isolating adult weevils into oviposition chambers, removing newly laid eggs to an incubation chamber to allow first instars to emerge before placing them onto food plants and collecting late instar larvae after 8 weeks. Mean survival of larvae from first instars to late instars is 54%± 7%. It enables continuous mass‐rearing of all development stages for laboratory bioassays.
