The effects of different apple varieties on the oviposition selection and growth and development of Cydia pomonella
In order to clarify the effects of different apple varieties on the oviposition selection and growth and development of codling moth,and to provide a certain reference for the sustainable control of codling moth,this experiment conducted indoor experiments on the effects of 18 varieties of apples,including Ruidan,Lujia 4,and Italian early red,on the oviposition selection and growth and development of codling moth.The results of the oviposition selection experiment showed that the codling moth had a stronger oviposition preference on Pingjin(5.31 eggs/fruit),Lujia 4(4.98 eggs/fruit),and Australia 4(3.80 eggs/fruit),while its oviposition preference was weaker on Changping 8(1.76 eggs/fruit),Huamei(1.96 eggs/fruit),and Ruidan(2.47 eggs/fruit).The results of the growth and development experiments showed that the codling moth feeding on Suanwang had the shortest larval stage(21.57 days)and the highest emergence rate(87.50%);Feeding on Lujia 4 and Pingjin resulted in high hatching rates of 49.91%and 49.89%,respectively;Feeding on Australia 4(23.23%)resulted in a high pupation rate,while feeding on Saijin and Ruidan resulted in emergence rates of only 31.25%and 20%,respectively;Feeding on Changping 8(37.15%)resulted in the lowest hatching rate;The larval stage(30.25 days)and pupal stage(11.50 days)of feeding on Huamei are the longest.Through comprehensive analysis of the data,it was found that the codling moth has weak adaptability on Saijin,Ruidan,Huamei,and Changping 8,while it has strong adaptability on Lujia 4,Suanwang,Pingjin,and Australia 4.
