“…Both hosts and parasitoids were obtained from colonies that were reared under laboratory conditions (25 ± 1°C, 60% ± 10% RH, 16L:8D photoperiod) on an artificial diet containing tea leaf powder. Other rearing details were described by Piyasaengthong, Sato, et al ().…”

“…The smaller tea tortrix, Adoxophyes honmai Yasuda (Lepidoptera: Tortricidae), is a common pest of tea plants ( Camellia sinensis L.) in Japan. Piyasaengthong, Sato, Kinoshita, and Kainoh () reported that female moths prefer to oviposit on the abaxial side of tea leaves, and the young larvae prefer to feed on young shoots and leaves. These preferences explain why damage caused by this species can be found on many parts of tea plants, especially on their leaves, affecting the productivity, quantity and quality of tea.…”

Ascogaster reticulata Watanabe (Hymenoptera: Braconidae) is an egg‐larval endoparasitoid of the smaller tea tortrix, Adoxophyes honmai Yasuda. Recent studies have examined tritrophic interactions among Camellia sinensis, A. honmai and A. reticulata, but the effect of non‐host insects on the induction of tea plant that may affect foraging behaviour of A. reticulata remains unclear. In this study, we selected two non‐host insects, Homona magnanima Diakonoff and Ostrinia furnacalis (Guenée), as representative species in our bioassays. Tea leaves were treated with homogenized female reproductive tissues of a non‐host insect in comparison with untreated leaves in a choice test. Residence times of parasitoids on both leaves were recorded. The parasitoids seemed to prefer walking on leaves treated with homogenates of H. magnanima over untreated leaves, but the difference in residence times was not significant. In contrast, its residence time on leaves treated with homogenates of O. furnacalis was significantly shorter than that on untreated leaves. Thus, the induction of tea leaf surface chemicals may differ among moth species, which may produce different types of elicitors. This difference may, in turn, affect the host‐searching behaviour of A. reticulata.

“…As offspring mortality values could depend on the phenological state of the leaf (Raupp & Denno, 1983;Piyasaengthong et al, 2016), leaf category was related to nymphal survival parameters. Oviposition preference based on leaf phenological state was determined by an exact binomial distribution test (P = 0.5) comparing the number of egg masses laid on each category.…”

“…Alkaloids are differentially distributed in the plant tissues, usually occurring in higher concentrations in younger leaves (Eltayeb et al, 1997). However, as no differences in hatching success were found between young and mature leaves, it is possible that other factors, such as physiological features of plants, or ecological constraints such as the presence of natural enemies, can determine oviposition site preference (Piyasaengthong et al, 2016). However, it is also possible that the preference of E. maculicornis for mature leaves as oviposition sites may be simply explained by their higher availability in the field.…”

1. Treehoppers (Hemiptera: Membracidae) exhibit a wide range of social behaviours related to maternal care and nymphal aggregation. Maternal care represents an investment in terms of time and energy leading to trade-offs which bear a strong relationship with parity and can thus affect population dynamics. These trade-offs can be modulated by biotic and abiotic features of the oviposition site.2. Preliminary observations on Ennya maculicornis (Membracidae: Similinae: Polyglyptini) show that females generally lay a single egg mass, and occasionally two or three egg masses, and that maternal care is a plastic trait because some females abandoned their egg mass before it hatched while other females remained with their offspring after egg hatching. These features make this species an interesting model to study the relationship between female fitness, maternal care and ecological factors such as oviposition site.3. The biology and natural history of E. maculicornis are described and the relationships in question analysed using demographic parameters estimated by matrix models. Ennya maculicornis showed sexual dimorphism and a longer developmental period than other species of the same tribe. Females exhibited maternal care that increased offspring survival, and preferred mature over young host leaves for oviposition. Finite rate of increase ( ) values were lower than 1, suggesting a tendency towards population decrease.4. The results represent the first detailed description of the life history and ecology for a species of this genus. Additionally, new hypotheses for treehopper sexual dimorphism, oviposition site choice and the ecological effects on population dynamics are proposed.
