The O. avara group of Oecetis is formally defined to include 4 described species, O. avara (Banks), O. disjuncta (Banks), O. elata Denning & Sykora, and O. metlacenis Bueno-Soria, and 15 new species. Oecetis marquesi Bueno-Soria, previously considered a member of the O. avara group, is treated as incertae sedis to species group, but is also redescribed and treated in the current work. New speci...

Diplodia scrobiculata, a latent pathogen of Pinus spp. and other conifers with a limited distribution in the United States, Mexico and southern Europe, has not been reported previously in the southern hemisphere. This is unlike its close relative Diplodia pinea that is found in most parts of the world where pines are native or have been introduced. During an intensive D. pinea survey conducted ...

In this studywe compared the performance of regression tree ensembles using hyperspectral data. More specifically, we compared the performance of bagging, boosting and random forest to predict Sirex noctilio induced water stress in Pinus patula trees using nine spectral parameters derived from hyperspectral data. Results from the study show that the random forest ensemble achieved the best over...

Root-lesion nematodes (primarily Pratylenchus penetrans) were monitored in two marigold cultivars (Tagetes tenuifolia cv. Nemakill and cv. Nemanon), annual ryegrass (Lolium multiflorum cv. Lemtal), red clover (Trifolium pratense cv. Florex), and soybean (Glycine max cv. Proteus), and in the following potato (Solanum tuberosum cv. Superior) crop during three growth sequences. Meadow fescue (Fest...

A molecular docking approach was employed to evaluate the binding affinity of six triterpenes, namely epifriedelanol, friedelin, ?-amyrin, ?-amyrin acetate, ?-amyrin and bauerenyl towards cannabinoid type 1 receptor (CB1). Molecular studies showed that epifriedelanol had strongest CB1. dynamics simulation revealed friedelin engaged in stable non-bonding interactions by a pocket close active sit...

The suppression of Meloidogyne incognita by marigolds differed among six marigold cultivars and five soil temperatures. Tagetes signata (syn. T. tenuifolia) cv. Tangerine Gem and the Tagetes hybrid Polynema allowed reproduction and root galling when grown at 30 degrees C, and should not be used for control of M. incognita at temperatures close to 30 degrees C. Tagetes patula cultivars Single Go...

Four weeds (Acorus calamus, Artemisia tridentata, Heliopsis longipes, and Tagetes minuta) and three cultivated plants (Azadirachta indica, Mammea americana, and Ocimum basilicum) are potential candidates for crop development and commercialization for sources of insect attractants, repellants, or toxicants. Although all could be commercially viable, the neem tree (A. indica) is by far the most l...
