Effect of laminarin (Lam) treatment on tea plants’ direct and indirect resistance to TLH. (a) The mean number of TLH female adults (+SE, n = 6) on plants treated with laminarin vs. control plants, 0.5–48 h after exposure. (b) Mean percentage (+SE, n = 6) of TLH eggs per plant on pairs of plants, 72 h after the release of TLH. (c) Mean percentage (+SE, n = 6) of survival rate of TLH female adults per plant on control and laminarin-treated plants. (d) Behavioral responses of TLH egg parasitoid S. empoascae female adults to different plant volatiles released from pairs of odors: Control plants (Con) versus laminarin-treated plants (Lam); TLH-infested plants (TLH) versus both laminarin and TLH-treated plants (Lam + TLH). The values represent means + standard error (SE) of six repeats. Asterisks indicate significant differences between members of a pair (*P < 0.05; **P < 0.01; Student’s t-test).
