“…Under the Type I mechanism, the low level of genetic diversity is expected to produce in this species a correspondingly low degree of ecological generalism. In reality, however, the host range of the gypsy moth is one of the largest in Lepidoptera (Zlotina et al , 1998), not only in the Old World but also in North America, where gypsy moth colonisation was accompanied by a population bottleneck and further loss of genetic diversity (Harrison et al , 1983; Bogdanowicz et al , 1997).…”

Abstract. 1. If ecological generalism is an evolving heritable trait, we need to study the underlying genetics in order to understand the nature of this fundamental phenomenon.2. I consider two alternatives. Under the Type I mechanism, ecological generalism is exclusively a population property. Under the Type II mechanism, generalism can vary among genotypes as well as among populations.3. The genetics underlying the Type I mechanism is straightforward, whereas Type II genetics is less so. I propose that a broad adaptive range of generalist genotypes can be a result of a pleiotropic modifier that, when expressed, renders fitness of the carrier relatively insensitive to environmental variance.4. A review of the theory and the data indicates that stable ecological generalism is more likely to occur under the Type II compared to the Type I mechanism. Type II generalism appears to be relatively more common and more compatible with patterns observed in the wild.5. Generalism of natural enemies is a key factor influencing the effectiveness of conservation biological control (CBC). I argue that natural enemies with Type II generalism are relatively more suitable for CBC applications, and spell out directions for further research.

“…The Asian Juglans mandshurica , the American Juglans cinerea and the American Carpinus caroliniana were similar. Survival was poor, and further development nil, on the other trees investigated (the American Juglans nigra , the European Alnus glutinosa , two American Fraxinus spp., and various conifers (Zlotina et al ., 1998).…”

“…The rosy spongy moth, Lymantria mathura Moore (Erebidae, Lepidoptera), is a polyphagous insect herbivore of high ecological and economic importance. The species is native to the Russian Far East, India, northern China, and Japan (Zlotina et al., 1998). It feeds on a variety of broadleaf trees, including ca 20 different families (Volf et al., 2017; Zlotina et al., 1998).…”

Polyphagous insect herbivores feed on multiple host‐plant species and face a highly variable chemical landscape. Comparative studies of polyphagous herbivore metabolism across a range of plants is an ideal approach for exploring how intra‐ and interspecific chemical variation shapes species interactions. We used polyphagous caterpillars of Lymantria mathura (Erebidae, Lepidoptera) to explore mechanisms that may contribute to its ability to feed on various hosts. We focused on intraspecific variation in polyphenol metabolism, the fates of individual polyphenols, and the role of previous feeding experience on polyphenol metabolism and leaf consumption. We collected the caterpillars from Acer amoenum (Sapindaceae), Carpinus cordata (Betulaceae), and Quercus crispula (Fagaceae). We first fed the larvae with the leaves of their original host and characterized the polyphenol profiles in leaves and frass. We then transferred a subset of larvae to a different host species and quantified how host shifting affected their leaf consumption and polyphenol metabolism. There was high intraspecific variation in frass composition, even among caterpillars fed with one host. While polyphenols had various fates when ingested by the caterpillars, most of them were passively excreted. When we transferred the caterpillars to a new host, their previous experience influenced how they metabolized polyphenols. The one‐host larvae metabolized a larger quantity of ingested polyphenols than two‐host caterpillars. Some of these metabolites could have been sequestered, others were probably activated in the gut. One‐host caterpillars retained more of the ingested leaf biomass than transferred caterpillars. The pronounced intraspecific variation in polyphenol metabolism, an ability to excrete ingested metabolites and potential dietary habituation are factors that may contribute to the ability of L. mathura to feed across multiple hosts. Further comparative studies can help identify if these mechanisms are related to differential host‐choice and response to host‐plant traits in specialist and generalist insect herbivores.
