Summer Dendrology

 Dendrology is the study of woody plants and trees identification and taxonomy, and a really big part of the foundational knowledge for field researchers, naturalists, hunters and fishermen, canoeists and kayakers, and especially those who are all of the above.

Here is a list of trees someone might find on the lower South Branch of the Potomac and surrounding areas in Hampshire County (WV) or Allegany County (MD).

Predation of Spotted Lantern Flies

 

Predation of spotted lanternfly (Lycorma delicatula) by generalist arthropod predators in North America

Abstract: Spotted lanternfly (Lycorma delicatula White, (Hemiptera: Fulgoridae)) is a non-native, invasive pest with a broad host range that has rapidly spread since its discovery in the United States in 2014. Managing emerging invasive pests can be challenging as repeated insecticide inputs can lead to resistance and impact non-target organisms. Alternative strategies, such as biological control, reduce risks but require extensive investigation before implementation. A recent community science study suggests that arthropods are major predators of L. delicatula. However, this pest can sequester toxins from its preferred host, tree of heaven (Ailanthus altissima), which may defend it from predation. Thus, we tested a variety of predatory arthropods against all life stages of L. delicatula to determine if they would avoid prey fed on A. altissima compared to other host plants. Predatory arthropods did not show a preference when given a choice between L. delicatula reared with access to A. altissima compared to those reared on alternative hosts. We then tested 10 commercially available or easily field-collected generalist predators to determine if these potential biological control agents could reduce L. delicatula populations. Spined soldier bugs (Podisus maculiventris (Say, Hemiptera: Pentatomidae)), Carolina mantids (Stagmomantis carolina (Johansson, Mantodea: Mantidae)), and Chinese mantids (Tenodera sinensis (Saussure, Mantodea: Mantidae)) were the most effective at reducing prey populations, indicating they have promise as effective natural control agents. Our results also suggest that conservation and/or augmentation biological control using generalist predators already present in the landscape could be a useful management strategy for L. delicatula.

Mullein - an uncommon, nonnative plant

The Great (or common) mullein, Verbascum thapsus, is native to Europe, northern Africa, and Asia, and introduced in the Americas, Australia and New Zealand.  This biennial (two-year life cycle) plant grows to more than 2 meters every other year. It prefers sunny, disturbed soils, and it can even survive between the stones of a patio.  Mullein can be invasive in temperate regions, but does not survive in shade or from tilling. It does host some insects that can be harmful to other plants. It is widely reported as medicinal, but no approved drugs are made from mullein. It can also be used for making dyes and torches, and can even be used when toilet paper would be necessary but not available.

Oldtown Bridge floods again

 The poor old bridge connecting Maryland and West Virginia over the North Branch of the Potomac has been flooded more often than I can remember in previous years.  (Looking North from Green Spring, WV)
