Tent Caterpillar

Tent caterpillars of the genus Malacosoma frequently appear in outbreak numbers causing widespread defoliation of trees and shrubs in North America. The western tent caterpillar, M. californicum (Packard), with six subspecies, occurs over most of temperate western North America and although there is a large number of host plants on which it will oviposit and feed (Stehr and Cook 1968), most have little commercial value. We report here the identification of a component of the female sex pheromone of M. californicum.

The pink bollworm, Pectinophora gossypiella (Saunders), has become increasingly important as a primary pest of cotton, Gossypium hirsutum L., in the Lower Colorado Desert of western North America. New species of natural enemies have not become established although annual parasite releases have shown some favorable results (Legner and Medved 1979). The effects of a pyrethroid, female sex pheromone, and annual parasite releases on pink bollworm suppression were studied and compared.

Scalable Synthesis

Mathuralure (1) is the major sex pheromone component of the pink gypsy moth Lymantria mathura, a potentially devastating invasive species to North America. To support population monitoring of this moth, a gram-scale synthesis of (–)-mathuralure (1) was developed. This process relies on coupling an alkynyl lithium species with a chloroepoxide and provides access to the natural product in a 10% yield over 10 steps.

Rhagoletis Zephyria

Abstract Closely related phytophagous insects that specialize on different host plants may have divergent responses to environmental factors. Rhagoletis pomonella (Walsh) and Rhagoletis zephyria Snow (Diptera: Tephritidae) are sibling, sympatric fly species found in western North America that attack and mate on plants of Rosaceae (~60 taxa) and Caprifoliaceae (three taxa), respectively, likely contributing to partial reproductive isolation. Rhagoletis zephyria evolved from R. pomonella and is native to western North America, whereas R. pomonella was introduced there. Given that key features of the flies’ ecology, breeding compatibility, and evolution differ, we predicted that adult eclosion patterns of the two flies from Washington State, USA are also distinct. When puparia were chilled, eclosion of apple- and black hawthorn-origin R. pomonella was significantly more dispersed, with less pronounced peaks, than of snowberry-origin R. zephyria within sympatric and nonsympatric site comparisons. Percentages of chilled puparia that produced adults were ≥67% for both species. However, when puparia were not chilled, from 13.5 to 21.9% of apple-origin R. pomonella versus only 1.2% to 1.9% of R. zephyria eclosed. The distinct differences in eclosion traits of R. pomonella and R. zephyria could be due to greater genetic variation in R. pomonella, associated with its use of a wider range of host plants than R. zephyria.

Everyone who travels the forests or roads of Ontario and the provinces east of it must be familiar with the tent caterpillars of the genus Malacosoma. The best known of these is the orchard, eastern, or American tent caterpillar, Malacosoma americana Fab., which makes its large grey “tents” on chokecherry, apple, hawthorn, wild plum and other trees and shrubs, chiefly of the family Rosacea.

Fungal Genus

Coniferiporia, belonging to Hymenochaetaceae and recently segregated from Phellinidium, is a wood-inhabiting fungal genus with three species, each having a specific geographic distribution and a strong host specificity as a forest pathogen of coniferous trees. In this study, the species diversity of Coniferiporia is further clarified with the aid of a wider sampling and multilocus-based phylogenetic analysis, which reveals a new species C. uzbekistanensis. The molecular clock and ancestral geographic origin analyses indicates that the ancestor of Coniferiporia emerged in one of the Pinaceae and Cupressaceae and then jumped to the other plant family originated in eastern Eurasia 17.01 million years ago (Mya) (95% highest posterior density: 9.46–25.86 Mya) and later extended its distribution to western North America, Central Asia and eastern Europe. Coniferiporia sulphurascens speciated on Pinaceae in eastern Eurasia 8.78 Mya (9.46–25.86 Mya) and then extended its distribution to western North America and eastern Europe. Coniferiporia qilianensis and C. uzbekistanensis speciated on Juniperus przewalskii in eastern Eurasia 3.67 Mya (0.36–8.02 Mya) and on J. polycarpos in Central Asia 4.35 Mya (0.94–8.37 Mya), respectively. The speciation event of C. weirii occurred 4.45 Mya (0.77–9.33 Mya) right after the emergence of its host, the endemic Cupressaceae species Thuja plicata, and soon after, this fungus evolved to also inhabit another endemic Cupressaceae species Calocedrus decurrens. In summary, this study for the first time unambiguously clarified and timed the adaptive evolutionary event of Coniferiporia in association with its biogeography and host plants.
