SCHOWALTER Department of Entomology, Oregon State University, Corvallis, Oregon 97331 Environ. Entomol. 15: 1055-1056 (1986) ABSTRACT Overwintering behavior of Boisea rubrolineatus (Barber) was studied during 1984-85. Large numbers of this insect aggregated on a single, large Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco, tree, with deep bark fissures, at the edge of a stand ca. 1 km from a grove of maples, Acer macrophyllum Pursh, the feeding host. Other trees near the over- wintering site were smaller and lacked deep bark fissures, or were shaded by trees along the edge of the stand. Density measurement was used to estimate number of overwintering insects at ca. 8,000. These results demonstrate the degree of aggregative behavior in this insect and suggest that aspects of stand structure influence the availability of suitable over- wintering sites. KEY WORDS Boisea rubrolineatus, population dynamics, forest structure, resource uti- lization, overwintering site selection THE SURVIVAL OF overwintering adults of several pies, Acer macrophyllum Pursh, ca. 1 km N of the forest insect species may be critical to population overwintering site.

  • Hemiptera: Heteroptera) with a Review of the Eggs of This Family

The external morphology of eggs and manner of oviposition of three rhopalid species, Brachycarenus tigrinus (Schilling, 1829), Chorosoma schillingi (Schilling, 1829) and Rhopalus (Aeschyntelus) maculatus (Fieber, 1837) are described. The eggs were studied using Scanning Electron Microscopy (SEM), and the results complete previous observations.The emphasis of the study is on the characteristics of eggs and details of oviposition in representatives of the family Rhopalidae. The chorionic origin of attachment stalk was confi rmed only in the Chorosomatini. A completely smooth egg chorion was recognized in R. (A.) maculatus, as a unique condition within at least the Pentatomomorpha. Key words. Rhopalidae, Rhopalini, Chorosomatini, Brachycarenus tigrinus, Cho- rosoma schillingi, Rhopalus (Aeschyntelus) maculatus, egg structure, micropylar processes, chorion, attachment stalk, oviposition Introduction Heteroptera eggs have a stable shape due to a sclerotized chorion. Egg morphology is helpful for taxonomic and phylogenetic purposes. The morphology of heteropteran eggs varies distinctly among taxa; for details see two monographs: SOUTHWOOD (1956) and COB- BEN (1968). Both authors mentioned that the eggs of the coreoid family Rhopalidae have a specifi c morphological pattern (e.g. two micropylar processes). COBBEN (1968) not only compared the morphology of heteropteran eggs but made phylogenetic inferences from their important characters.

The red-shouldered soapberry bug (Jadera haematoloma) was locally adapted 12 to feed on the seeds of an introduced and a native host plant in Florida in the 1980s. By 2014, 13 local differentiation was lost and replaced by phenotypically similar populations all adapted to 14 the introduced host, likely as a result of gene flow. Here, I quantify the effects of these two host 15 plants on individual performance, natural selection, and phenotypic plasticity. I find that the seed 16 coat and seedpod of the native host have strong negative effects on juvenile survival and adult 17 reproduction compared to the introduced host. I find support for the hypothesis that the seedpod 18 is driving diversifying natural selection on beak length, which was previously locally adapted 19 between hosts. I also find maladaptive plasticity induced by host plant: bugs develop beak 20 lengths that are mismatched with the seedpod size of the host they are reared on.

  • Introduction to True Bugs (Heteroptera) of the Neotropics
    Chapter 1 Introduction to True Bugs (Heteroptera) of the Neotropics Antônio R. Panizzi and Jocêlia Grazia Abstract True bugs (Heteroptera) are a diverse and complex group of insects, particularly in the neotropics. The fauna ofthese bugs has been investigated through time, but our knowledge of the species living in the Neotropical Region is lirnited. ln this introductory chapter, we give a general view on true bugs c1assification and biogeography, with concise comments on their general characteristics and bioecology of each major taxon that comprise each of the seven infraorders of Heteroptera. 1.1 Introduction The true bugs (Heteroptera) constitute a very interesting widely distributed group of insects, which is greatly diversified in tropical zones. Considered the largest group of insects with incomplete metamorphosis, heteropterans have been studied on both basic and applied aspects worldwide. Along the years, several books have been published on Heteroptera, the majority on specific aspects, such as certain groups (taxa) of particular areas, and others on more general comprehensive issues. Of more broad interest, two books about the latter were published relatively recently. The first was dedicated to the c1assification and natural history of true bugs in particular, with insights on the history of the study of Heteroptera, how to collect and preserve true bugs, historical biogeogra- A.R.

When J. haematoloma appears in large colonies in yards and gardens, people become curious and/or alarmed and contact agricultural officials for information. Mothers often become upset over their children's clothes being stained red from the squashed bodies of J. haematoloma, due to their children playing on infested lawns. The bugs Figure 1.

There is also a single record from Los Angeles, California (Gildenhuys et al., 2013). The species has been introduced intentionally to many regions of the world as a popular ornamental plant. The species is widespread and highly invasive in subtropical regions in Australia and South Africa. Some consider parts of Asia as the native range of the species but it is not listed anywhere in the region except Sri Lanka, where it is considered introduced (CABI, 2016). The introduction of C. grandiflorum into South Africa as an ornamental plant occurred around 100 years ago (Simelane et al., 2011). The species rapidly spread and is now considered invasive in five of the country’s nine provinces, of which the Kwazulu-Natal and the Eastern Cape provinces are the most severely affected (Henderson, 2001; Simelane et al., 2011).
