Abstract:

A new method of collecting Carposina sasakii Matsumura eggs is describedVillus height and density of egg cards was determined using a microscope. There was no difference in the total average number of eggs laid, or their hatching rate, on suede wallpaper (303.77+-51.03) vs scraped filter paper (330.23+-44.85)However, there was a significant difference in the average number of eggs laid on these two substrates within 48 hours of mating (176.31+-38.96 vs 223.92+-30.69; P < 0.001). The average hatching rates for each substrate were 93.97% and 94.56%, respectively. After an additional 48 hours, hatching rates decreased to 83.87% and 83.87%; i.e. the hatching rate on both substrates was significantly higher after 48 hours than after 96 hours (P < 0.001). There was no significant difference in the hatching rate of eggs laid within the same time period on each substrate. Oviposition on suede wallpaper can greatly increase the number of early larvae, and reduce the cost of producing the same number of insects. Suede wallpaper substrate was clearly more cost effective than the traditional method of handpainting egg cards and consistently produced better results.
