PRECISE AND TALSTAR AGAINST THRIPS INFESTING POTTED ANTHURIUM, 2004

Pyrethroid-resistant onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), infesting persimmon fruit

A total of 53 strains of onion thrips, Thrips tabaci Lindeman, were established, of which 14 strains were collected from persimmon fruit and 39 strains from a vetch weed, Vicia angustifolia, in commercial persimmon orchards in Wakayama Prefecture. Susceptibility to insecticides was evaluated by the Petri dish-spraying tower method. Pyrethroid-resistant strains and pyrethroid-susceptible strains...

Precise Decision Language: (Comment on Howard 2004)

Like Howard (2004), I believe it is important to use precise language in our field and that our language should be “plain speaking,” familiar, and fundamental. Precise language makes it easier for us to communicate with each other and easier for students, clients, and others to grasp the ideas of decision analysis. Howard proposes some “modest” changes to our language that he suggests “will mak...

Differentiated Microelement Content in Anthurium (anthurium Cultorum Birdsey) Leaves*

The main objective of the study was to determine the nutritional status in terms of the content of microelements, such as iron, manganese, zinc, copper and boron in several standard cultivars of anthurium (Anthurium cultorum Birdsey) called Baron, Choco, Midori, Pistache, President and Tropical. The plants were grown in expanded clay (ř 8-18 mm) using drip fertigation with standard nutrient for...

Oral toxicity of bacterial toxins against thrips species

The oral toxicity of excretion products of several Photorhabdus and Xenorhabdus strains was tested on two thrips species: Frankliniella occidentalis and Thrips tabaci. Out of 46 Photorhabdus isolates and 6 Xenorhabdus isolates only 6 North American P. temperata isolates were toxic to the thrips species. After 7 days of drinking from P. temperata supernatant a mortality of 90% could be reached. ...
