The effectiveness of inundative releases of the parasitoid Eretmocerus eremicus n. sp. Rose & Zolnerowich for control of Bemisia argentifolii Bellows & Perring on poinsettia in replicated experimental greenhouses was determined. We evaluated two release rates of E. eremicus: a low release rate (one female per plant per week, released in two greenhouses, in spring 1995) and a high release rate (...

Cyperus rotundus L. has been widely distributed in China. In the exploration of Cyperi Rhizoma to pat attention on its geoherbalism is very necessary. The current index of quality control for Cyperi Rhizoma and Cyperus rotundus-volatile oil is the αCyperone contained in the Cyperus rotundus-volatile oil, different processing methods influence the content of their αCyperone. On the basis of the ...

Theory predicts that intraguild consumers such as predators or parasitoids may displace more specialized heterospecific competitors and thereby actually increase the population densities of a shared host or prey. We tested this idea with a native primary parasitoid, Eretmocerus eremicus, and an exotic autoparasitoid Encarsia sophia, both attacking the sweetpotato whitefly Bemisia tabaci. Autopa...

In the present study antioxidant activity of the plant was assessed. For this purpose Cyperus rotundus was extracted by using different extraction solvents and evaluated for their antioxidant activity using different in vitro antioxidant assays. Total flavonoids contents in methanol extracts of Cyperus rotundus (8.15-18.25 mg CE/g of dry matter) were higher as compared to ethanol extracts (6.44...

i t a c s s w p l b g The efficacy and cost of reduced release rates of the parasitoid Eretmocerus eremicus Rose and Zolnerowich (Hymenoptera: Aphelinidae) when combined with application of the insect growth regulator buprofezin were compared to those of a higher parasitoid release rate used alone for whitefly control (Homoptera: Aleyrodidae) on poinsettia (Euphorbia pulcherrima Willd. ex Koltz...

Of 198 deermice (Peromyscus spp) collected from various localities in the southwestern United States and northern Mexico, 106 (54%) had eimerian oocysts in their feces when examined. These included 50 of 106 (47%) Peromyscus truei, 34 of 54 (63%) Peromyscus maniculatus, 4 of 17 (24%) Peromyscus leucopus, and 18 of 21 (86%) Peromyscus eremicus. The following Eimeria were identified from infected...

Cataract is a clouding that developes in the crystalline lens of the eye or in its envelope, varying in degree from slight to complete opacity and obstructing the passage of light. Cataract was induced by incubating the chick lenses in 55mM glucose for 72 hours at 370C. Impact of hydroalcoholic extract of various concentrations was studied on the levels of trace elements, electrolytes, total pr...
