摘　　要：以平均落卵量、落卵所占百分比和不同松针上幼虫数量为评价指标,研究云南松毛虫Dendrolimus houi Lajonquière和思茅松毛虫Dendrolimus kikuchii Matsumura对寄主思茅松Pinus kesiya var.langbianensis,华山松P.armandii,油松P.tabulaeformis,白皮松P.bungeana的成虫产卵选择和幼虫取食选择趋性。结果表明:云南松毛虫在思茅松,华山松,油松,白皮松上的成虫平均落卵百分比分别为46.98%,26.10%,22.73%,4.19%;思茅松毛虫在思茅松,华山松,白皮松,油松上的成虫平均落卵百分比分别为48.22%,23.55%,15.80%,12.44%。在36 h观测时间内,云南松毛虫和思茅松毛虫幼虫对4种松树的取食选择趋性不一致,且与成虫产卵选择趋性不一致。The adult oviposition and larvae feeding preference of Dendrolimus houi Lajonquiere and D. kikuchii Matsumura to Pinus kesiya var. langbianensis, P. armandii, P. bungeana, and P. tabulaefor- mis were assessed. The results indicated that the amount of D. Houi eggs ranked as P. kesiya vat. lang- bianensis,P, armandii, P. tabulaeformis, P. Bungeana, percentage of eggs were 46. 98%, 26. 10%, 22. 73% ,4. 19% ,respectively;and as for D. kikuchii, the ranking was P. kesiya vat. langbianensis, P. armandii, P. bungeana, P. tabulaeformis, percentage of eggs were 48.22%, 23.55%, 15.80%, 12. 44% ,respectively. During 36 hours observation time,the larvae feeding preference of D. houi and D. kikuchii to P. kesiya vat. langbianensis , P. armandii, P. bungeana, and P. tabulaeformis was inconsis- tent, and it was inconsistent with the adult ovipositon preference.
