The complex life-cycles of Maculinea butterflies and their interactions with Myrmica ants have been studied extensively both in the field (eg Chapman, 1916a, b; Frohawk, 1916, 1924; Thomas, 1980, 1995; Elmes et al., 1991a) and, to a lesser extent, in the laboratory.

By eliminating the food plant, Asclepias curassavica, monarch butterflies, Danaus plexippus, have virtually eliminated milkweed bugs, Oncopeltus spp., from the island of Barbados. The relatively open terrain of Barbados means the plants have no refuge; the butterflies survive on an alternate milkweed food plant, Calotropis procera, whose thick-walled pods make seeds unavailable to the bugs.

The ability of the insects to sequester secondary compounds from host plants was studied in detail in central California. A colorimetric assay was used to quanitify the amount of cardenolides (cardiac glycosides) in the lygaeid bugs Oncopeltus fasciatus and Lygaeus kalmii kalmii and nine species of milkweed host plants.

Some Aspects of the Sequestration of Cardenolides in the Large Milkweed Bug, Oncopeltus Fasciatus (Dallas) (Hemiptera: Lygaeidae)

Department of The University of British Columbia 1956 Main Mall Vancouver, Canada V6T 1Y3 OE-6 (3/81) ii ABSTRACT Specific aspects of the selective sequestration, excretion and tolerance of cardenolides in the large milkweed bug, Oncopeltus fasciatus have been studied using spectrophotometry assays, thin-layer chromatography, tracer studies, in vivo tolerance assays, and enzyme inhibition techniques. The cardenolide content of the dorsolateral space, gut, wings and fat body of Oncopeltus fasciatus was examined. The results indicate that the majority of cardenolides sequestered in the insect are concentrated in the dorsolateral space, which confirms the basic pattern of quantitative distribution of cardenolides in fJ.

The Story of an Organism: Common Milkweed
THE STORY OF AN ORGANISM: COMMON MILKWEED Craig Holdrege All I am saying is that there is also drama in every bush, if you can see it. When enough men know this, we need fear no indifference to the welfare of bushes, or birds, or soil, or trees. We shall then have no need of the word “conservation,” for we shall have the thing itself. Aldo Leopold (1999, p. 172) I had casually observed common milkweed (Asclepias syriaca, Asclepiadaceae) but never paid too much attention to it. True, I was fascinated by its big globes of flowers and, in the fall, by its beautiful seeds that floated through the air on their tufts of white silk. I also knew that common milkweed is the main food plant for monarch butterfly larvae. But it was only when I was preparing for the 2006 summer course at The Nature Institute and when I noticed the flowers of common milkweed beginning to open, that I looked closely at them for the first time. I realized that the plant has a highly complex flower structure and, in addition, observed how the flowers were being visited by many different insects. Milkweed had finally caught my attention, and I decided that we should focus on it for our initial plant study in that weeklong course. This study proved to be particularly intense. Milkweed drew us all into its world of refined structures. It took us a good while just to get clear about the flower parts and their relation to more “normal” flowers. (There were a number of trained biologists in the course.) We also observed interaction with insects and saw how flies sometimes became caught in the flowers and died.

However, there are gaps in our knowledge about the survival of first, or spring generation, monarchs in their core areas of Texas, Oklahoma, and Louisiana. This is important because the spring generation represents the first stage of annual recovery from overwinter mortality. It is, therefore, an important stage for monarch conservation efforts. This study showed that, in the context of a complex arthropod community in north Texas, first generation monarch survival was high. The study found that survival was not directly related to predators on the host plant, but was higher on host plants that harbored a greater number and variety of Citation: Stevenson, M.; Hudman, other, non-predatory arthropods. This is possibly because the presence of alternate, preferable prey K.L.; Scott, A.; Contreras, K.; enabled monarch eggs and larvae to be overlooked by predators.

Seed Preference of Milkweed Bugs (Oncopeltus Fasciatus) (Hemiptera: Lygaeidae) in Trinidad
Seed preference of Milkweed Bugs (Oncopeltus fasciatus) (Hemiptera: Lygaeidae) in Trinidad Kathryn M. Alvarado Abstract- Oncopeltus fasciatus, commonly known as Milkweed bugs, are specialized seed feeders that use a proboscis for piercing and sucking. Milkweed seeds are a critical part of their diet and provide sustenance for each instar into adulthood. Little information is known about the seed preferences of Milkweed bugs which is mainly due to lack of research. This study serves to provide additional research and information regarding Oncopeltus sp. and their feeding behaviors as well as seed preferences. A total of 40 bugs were collected at two different collection sites. Three types of seed- bearing fruits were experimentally tested over three time periods during each day. Balata and cashew seeds were more commonly preferred over other seed choices. The bugs were seen actively feeding during the evening hours more often than morning or afternoon hours. Additionally, this specific species was observed engaging in cannibalistic acts. The overall purpose of this experiment was to determine seed preferences and time of feeding activity for the Oncopeltus species. Through this experiment, Milkweed bugs are better understood and researchers are able to use this information to conduct further research regarding their diets in accordance with seed preference. Introduction Oncopeltus fasciatus is a member of the Lygaeidae family that is comprised of more than 60 genera of seed feeding insects. This specific species undergoes incomplete metamorphosis with five different instars before reaching adulthood. Milkweed bugs in Trinidad have not been widely researched. However, several studies have been conducted in the United States in regions such as Texas, Georgia, and Missouri discussing coloration and wing span in relation to gender and size (Davis 2009).
