An economic comparison of biological and conventional control strategies for whiteflies (Homoptera: Aleyrodidae) in greenhouse poinsettias.
The objective of this study was to evaluate the costs of biologically controlling infestations of silverleaf whitefly, Bemisia argentifolii Bellows & Perring, in New England greenhouse operations on poinsettia, Euphorbia pulcherrima Wild, ex Koltz, using the parasitic wasp Encarsia formosa Gahan (Nile Delta strain). Partial budget analysis was used to compare costs for conventional verses biolo...

Biological Control of Bemisia argentifolii (Homoptera: Aleyrodidae) on Poinsettia with Inundative Releases of Encarsia formosa (Hymenoptera: Aphelinidae): Are Higher Release Rates Necessarily Better?
The effectiveness of inundative releases of the parasitoid Encarsia formosa for control of Bemisia argentifolii on poinsettia was determined in replicated experimental greenhouses. We evaluated two release rates of E. formosa: a low release rate (1 wasp/plant/week, released in two greenhouses, in spring 1995) and a high release rate (3 wasps/plant/week, released in two greenhouses, in fall 1993...

سفید بالکهای پنبه, بویژه دو گونه Bemisia tabaci (Genn.) (Hom.: Aleyrodidae)و Bemisia argentifolii Bellows and Perring از مهمترین آفات محصولات زراعی ، گلخانه و گیاهان زینتی در ایران هستند؛ که علاوه بر تغذیه از شیره گیاهی, به دلیل انتقال بیماریهای ویروسی، ترشح عسلک و در نتیجه کاهش در فتوسنتز گیاهان, از اهمیت زیادی برخوردار می باشند. با انگیزه شناسایی و تعیین پراکنش بیوتیپ‌های سفیدبالک پنبه، 11 ...

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 (...
