The oriental fruit moth (OFM), Grapholita molesta (Busck), is one of the dominant fruit-boring pests worldwide. In order to conduct integrated control of OFM effectively, it is important to predict the optimum control period. OFM populations have been monitored either by the number of trapped male moths exposed to sex pheromones or by the number of trapped male and female moths using food traps in orchards. The mating status and development stage of the trapped moths have not been characterized. The present paper studies the anatomical morphology of the OFM reproductive system at different development periods. The results revealed that OFM ovarian development can be divided into six stages. The average daily fecundity of OFM had an excellent positive correlation (r = 0.86) with the percentages of OFM in the egg maturation & oviposition stage, which could be used as an indicator in field population prediction work. There were obvious differences in the morphology of the corpus bursa and the heavy muscular area of the ductus ejaculatorius simplex before and after mating, and these differences could be used to increase the accuracy in predicting the optimum OFM control period.

Apatura laverna is subordinate to Apatura Fabricius of Nymphalidae, and endemic to China. The complete mitochondrial genome of A. laverna was sequenced and analyzed in the study. The length of the complete mitogenome is 15,187 bp, including 37 genes and a control region. COI gene initiate with a CGA codon, the rest 12 genes start with typical ATN. Eleven of 13 PCGs have a complete stop codon TAN except for COII and ND4 have a single T. The phylogenetic analyses support that A. laverna has a close relationship with the clade including A. metis and A. ilia.

The complete mitochondrial genome of Pontia edusa was sequenced and analyzed in the study. The length of the complete mitogenome is 15,125 bp, including 37 genes and a control region. Twelve genes start with typical ATN, but COI gene initiate with a CGA codon. Twelve of 13 PCGs have a complete stop codon TAA or TAG except for COI has an incomplete stop codon T-. Twenty-one of the 22 tRNAs have a typical cloverleaf secondary structure. The tRNA Ser(AGN) gene lacked the DHU loop. Bayesian analyses highly support the monophyly of Pieridae. In Pieridae, P. edusa is subordinate to the Pierinae clade.
