Leaf wetting is often considered to have negative effects on plant function, such that wet environments may select for leaves with certain leaf surface, morphological, and architectural traits that reduce leaf wettability. However, there is growing recognition that leaf wetting can have positive effects. We measured variation in two traits, leaf drip tips and leaf water repellency, in a series ...

Nonlethal alternatives are needed to manage blackbird (Icterids) damage to rice and sunflower production in the United States. We evaluated 4 registered fungicides on rice seeds (i.e., AllegianceH FL, Thiram 42-S, TrilexH, and VitavaxH 200 preplant seed treatments) and 2 foliar pesticides on sunflower seeds (Cobalt insecticide and Flock Buster bird repellent) as candidate blackbird repellents. ...

abstract indian meal moth, plodia interpunctella hübner (pyralidae) is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repel...

Eight essential oils of Chinese medicinal herbs (Angelica sinensis, Curuma aeruginosa, Cyperus rotundus, Eucalyptus robusta, Illicium verum, Lindera aggregate, Ocimum basilicum, and Zanthoxylum bungeanum) were obtained by hydrodistillation and the essential oil of Eucalyptus robusta leaves was analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 22 components of the essential oi...

The objective of this study was to quantify the influence of zinc oxide nanoparticles (nanoZnO) on the water repellency and dimensional stability of beech wood. Beech wood blocks were treated with a nano-ZnO solution at four treatment levels (0, 10,000, 20,000, and 40,000 ppm) using a modified dip method. Also, a thermal treatment was performed at 60 and 120°C. After conditioning the samples, w...

background: medicinal plant extracts such as those obtained from salvia species have a wide variety of chemical compounds in their essential oils. the repellency of a number of essential oils including those from the labiates like salvia against several insect species including the common house flies is reported. objective: the aim of this investigation was to find out the excito-repellency eff...

background: malaria is the most important vector-borne disease in many tropical countries all over the world. because of the widespread use of pyrethroid insecticide treated mosquito nets in the world, the effects of excito-repellency (er) phenomenon of pyrethroids against main malaria vector, anopheles stephensi were studied. methods: the er phenomenon of three concentrations of two synthetic ...
