“…This reduction increased with higher concentrations of the plant extract. Shekari et al (2008) also showed the α-amylase activity level in elm leaf beetle treated with A. annua extract, decreased after 24 h and sharply increased after 48 h. (rcfetetmtm gm extract caused the reduction of α-amylase activity in Ptfrtet rapae L. as was shown by Hasheminia et al (2011). The reduction of α-amylase activity by plant extracts could be due to the plant defense compounds that act on insect gut enzymes, α-amylases, and proteinases (Ryan 1990;Franco et al 2002).…”

Synthetic organic compounds and those of plant origin used in insect pest control are known to affect digestive enzymes and biochemical compounds. The lesser mulberry pyralid Glyphodes pyloalis Walker is a monophagous and dangerous pest of mulberry that has been recently observed in Guilan province, northern Iran. In this study the effect of the neem formulation, Achook (0.03% azadirachtin) was studied on nutritional physiology and gut enzyme activity of the lesser mulberry pyralid G. pyloalis. The LC 25 , LC 50 , and LC 90 values on 4th instar larvae were estimated as 113.6, 256.84, and 1,210.02 ppm, respectively. The neem insecticide exhibited a significant antifeedant activity when used at the highest concentration. When G. pyloalis larvae were provided with mulberry leaves treated with the neem extract, all nutritional indices, except approximate digestibility, decreased. Neem was found to affect digestive enzyme activities in the midgut of treated larvae. When larvae were fed on treated leaves, biochemical compounds in the hemolymph, such as protein, lipid, and glucose decreased but the amount of uric acid increased compared with the control.

“…Moreover, the essential oils made of S. hortensis, T. vulgaris and T. satureoides offer a high potential for the control of C. quinquefasciatus as new safety larvicides in the environment. Hasheminia et al [9] proved that the deterrent effect of Artemisia annua L. and A. millefolium L. on small cabbage Pieris rapae L. were 29.82% and 44.18%, respectively. In the another study, Kordan et al [7] assessed that A. millefolium can have a high deterrence effect in protecting stored products from S. granaris L. and T. castaneum Herbest.…”

“…Ateyyat et al [8] studied the effect of A. biebersteinii L. on adults of sweet potato whitefly, Bemisia tabaci Genn. The medicinal plants, Artemisia annua L. and A. millefolium have been reported deterrence activities against Pieris rapae L. [9] Beside essential oils, repellent potential of certain plant extracts such as thyme oil and some of its effective substances are known from the work of other authors. For example, Park et al [10] determined the repellent effectiveness of five monoterpenes (carvacrol, p-cymene, linalool, α terpinene and thymol) derived from the essential oil of Thymus sp.…”

Introduction: The greenhouse whitefly, Trialeurodes vaporariorum Westwood (Homoptera: Aleyrodidae), is an important cosmopolitan pest of many crops. Methods: The present study investigated the repellent and antioviposition activities of plant products from Achillea millefolium and Thymus vulgaris against this pest in greenhouse conditions. Cucumber plants were sprayed with the chemicals at 40 µl/ml concentration and control plants were treated with distilled water. Also, the essential oil of A. millefolium at the same volume (5 ml) was sprayed on the special filter paper (2×4 cm) attached at the petiole plant. Four treated plants and four control plants were placed randomly in to a cage. Three days after spraying, approximately 250 whitefly adults were released into the cages. Then three and six days after infesting, the number of eggs and adults were recorded. Each experiment was repeated two times at the same greenhouse condition. Results: The results revealed that all plant products affected the oviposition and tropism behaviors of greenhouse whitefly. Amongst the different treatments, the highest anti-oviposition effect was calculated by aqueous extracts of T. vulgaris (62.87 %) six days after treated. Moreover, the aqueous extract of A. millefolium had the highest repellent effect (52.54 %) six days after treatment. Also, the compare repellent activity of the chemicals on greenhouse whitefly adults indicated the highest repellent effect was evaluated by the essential oil of A. millefolium (48.07%) nine days after treatment. Conclusion: These results showed that A. millefolium and T. vulgaris had relatively long lasting repellent and anti-oviposition activities on the adults of the greenhouse whitefly.

“…Entre as diversas plantas pesquisadas na atualidade, Artemisia annua se destaca como uma das potenciais soluções para auxiliar no controle parasitário dos animais de produção (Hasheminia et al, 2011). Popularmente conhecida no Brasil como Artemísia ou Erva-deSão-João, é uma planta de origem chinesa, cultivada por determinados centros de pesquisa nacionais.…”

 RESUMOOs parasitas gastrintestinais causam enorme prejuízo econômico na bovinocultura, tanto nacional como mundial, ocasionado principalmente por Bunostumom sp., Cooperia sp. e Trichostrongylus sp. O objetivo deste trabalho foi determinar a eficácia in vitro do extrato hidroalcoólico de Artemisia annua (H.7) frente a esses endoparasitas. O H.7 foi produzido com sete dias de percolação a 4ºC e posteriormente liofilizado. Com esse fitoterápico, realizaram-se testes de eclodibilidade de ovos (TEO) e de migração larvar em ágar (TMLA), com seis repetições, com concentrações crescentes (0,78 a 50mg/mL). Para analisar a composição química do fitoterápico, procedeu-se à marcha fitoquímica completa. No TEO, a eficácia variou de 94,08±2,58% na maior concentração a 15,67±0,97% na menor concentração. Já no TMLA os valores encontrados variaram de 90,05±0,55% a 4,12±0,46%. Nas análises fitoquímicas, foram encontrados diversos compostos com propriedades de combater os nematódeos, tanto direta como indiretamente. Os resultados obtidos nos testes in vitro evidenciam que o extrato produzido possui potencial de combater nematódeos gastrintestinais de bovinos. Novos estudos devem ser realizados buscando maximizar a eficácia do H.7 e de outras extrações obtidas a partir de A. annua, uma vez que foram demonstrados excelentes resultados em ambos os experimentos.Palavras-chave: controle alternativo, fitoterapia, resistência parasitária ABSTRACT Gastrointestinal parasites cause economic losses to the cattle production, in
