The significance of host patch edges to the colonization and development of Corythucha marmorata (Hemiptera: Tingidae)

Abstract. 1. Corythucha marmorata (Hemiptera: Tingidae) was more abundant in clusters of small experimental patches of its host plant, goldenrod (Solidago altissima) , than in large patches covering the same area.
2. Adults and egg masses were more abundant on stems on the edges of the patches than on those in the interior.
3. Female Cmarmorata caged on edge plants laid more eggs than females caged on interior plants, and eggs on exposed plants developed faster than those in the middle of a pacth.
4. A preference for edges results in negative 'response' to patch size because large patches invariably have a lower proportion of edge than small patches.     

Habitat expansion of an exotic lace bug, Corythucha marmorata (Uhler) (Hemiptera: Tingidae), on the Kii Peninsula and Shikoku Island in western Japan

Habitat expansion of an exotic lace bug Corythucha marmorata (Uhler) was observed on the Kii Peninsula in 2003–2004, and on Shikoku Island between 2004 and 2007. The bug was first sighted in Nishinomiya City in Hyogo Prefecture in 2000, and then further south in central Kii Peninsula in 2003 before reaching the southern tip of the peninsula by 2004. The bug was first observed in the Tokushima and Ehime Prefectures of Shikoku Island in 2004, after which the range expanded and extended across the entire island by 2007. In this study, six wild Asteraceae species were identified as the host plants to the lace bug.

Maternal care in Gargaphia solani (Hemiptera: Tingidae)

We investigated the extent to which maternal behaviour exists in the lacebug Gargaphia solani as well as the adaptive relevance of maternal behaviour to predation, interspecific competition, feeding facilitation, and environmental heterogeneity. G. solani females aggressively defend their progeny against predators until maturity but provide no assistance in feeding, aggregating, or locating resources. In the absence of predators, nymphs suffer no ill effects if raised without their mother, but when nymphs are orphaned in normal field conditions only 3% survive to maturity. Such strong selection has given rise to maternal defensive behaviour that enables Gargaphia females to defend their progeny against predators.

Seasonal host alternation by the andromeda lace bug,Stephanitis takeyai (Heteroptera: Tingidae) between its two main host-plant species

I studied the seasonal occurrence of the andromeda lace bug,Stephanitis takeyai, on its two main host-plant species. In a secondary forest in Kyoto, this bug altered its hosts seasonally, i.e., from an evergreen shrub,Pieris japonica, in winter to a deciduous shrub,Lyonia elliptica, in summer. In contrast, in Nara park where fewL. elliptica were available, the bug exploited onlyP. japonica. Thus, seasonal host alternation by this bug is not obligate. A comparison of adult longevity and fecundity on the two host-plant species demonstrated the higher quality ofL. elliptica as a food resource. Corresponding to this difference in host quality, there was a dramatic difference in the seasonal population growth in the two study sites. In Nara, the population size at the beginning of the 2nd generation was almost the same as in the overwintered generation, whereas in Kyoto the population size in the 2nd generation was approximately one hundred times as large as in the overwintered generation. Thus seasonal host alternation is adaptive for the bug. In a previous study, I reported that overwintering as eggs in living leaves of their hosts is likely to be common among all the related species of this bug. Thus, this trait can be considered to be a phylogenetic constraint to the group. I speculate that host alternation by this bug has been derived because it is more adaptive from autoecy on an evergreen plant, similar to the pattern currently found in Nara, and that this bug can not only exploit deciduous host due to a phylogenetic constraint.
