The effects of host plant species and larval density on immune function in the polyphagous moth Spodoptera littoralis
<p>Immune functions are costly and immune investment is usually dependent on the individual's condition and resource availability. For phytophagous insects, host plant quality has large effects on performance, e.g. growth and survival, and may also affect their immune function. Polyphagous insects often experience a large variation in quality among different host plant species, and their immune investment may thus vary depending on which host plant species they develop on. Larvae of the polyphagous moth <i>Spodoptera littoralis</i>have previously been found to exhibit density-dependent prophylaxis as they invest more in certain immune responses in high population densities. In addition, the immune response of <i>S. littoralis </i>has been shown to depend on nutrient quality in experiments with artificial diet. Here, I studied the effects of natural host plant diet and larval density on a number of immune responses to understand if host plant species affects immune investment in generalist insects, and if the density-dependent prophylaxis could be mediated by host plant species. While host plant species in general did not mediate the density-dependent immune expression, particular host plant species was found to increase larval investment in certain functions of the immune system. Interestingly, these results indicate that different host plants may provide a polyphagous species with protection against different kinds of antagonisms. This insight may contribute to our understanding of the relationship between preference and performance in generalists, as well as having applied consequences for sustainable pest management.</p>
Fig 3 in Development of Microplitis similis (Hymenoptera: Braconidae) on two candidate host species, Spodoptera litura and Spodoptera exigua (Lepidoptera: Noctuidae)
Fig 3. Daily head-capsule width of parasitized and non-parasitized Spodoptera exigua (A) and S. litura (B). Each datum is shown as a mean ± SE. The asterisk means the referred columns differ significantly. Non-parasitized S. exigua larvae pupated on days 6 and 7, and thus for these 2 days no head-capsule width data for them are shown.
