Under field conditions, species displacements have occurred in different directions between the same invasive species of leafminers (Diptera: Agromyzidae). Liriomyza sativae (Blanchard) was displaced by L. trifolii (Burgess) in the western United States, with evidence suggesting that lower insecticide susceptibility of L. trifolii is a factor. However, in Japan, the opposite has occurred, as L....
Liriomyza sativae and L. trifolii (Diptera: Agromyzidae) are two highly invasive species of leafmining flies, which have become established as pests of horticultural crops throughout the world. In certain regions where both species have been introduced, L. sativae has displaced L. trifolii, whereas the opposite has occurred in other regions. These opposing outcomes suggest that neither species ...
BACKGROUND Closely related invasive species may often displace one another, but it is often difficult to determine mechanisms because of the historical nature of these events. The leafmining flies Liriomyza sativae and Liriomyza trifolii have become serious invasive agricultural pests throughout the world. Where both species have invaded the same region, one predominates over the other. Althoug...
Liriomyza sativae and L. trifolii are highly invasive leafminer pests of vegetable crops that have invaded southern China in recent years. Liriomyza sativae was the first of these species to invade China, but it is now being displaced by L. trifolii. The rate and extent of this displacement vary across southern China. In Hainan, monocultures of highly valuable cowpea are planted and treated ext...
مگس مینوز برگ، Liriomyza sativae (Blanchard)، یکی از آفات مهم سبزیجات در ایران و بسیاری از کشورهای جهان میباشد. بهمنظور تعیین سمیت (LC50) حشرهکشهای آبامکتین (8/1 درصد امولسیون)، سیرومازین (75 درصد پودر خیسا) و اسپینوزاد (24 درصد سوسپانسیون کلوئیدی) نسبت به L. sativae، زیستسنجی روی لارو سن اول، سن آخر و حشرهی کامل این آفت تحت شرایط دمایی 1 ± 25 درجهی سلسیوس، رطوبت نسبی 5 ± 65 درصد و دوره...
Liriomyza sativae Blanchard and trifolii (Burgess) are two highly polyphagous pests that successively invaded China in the 1990s 2000s, respectively, threatening vegetable horticultural plants. Competitive displacement of L. by occurred during expansion process latter southern China, while whether can expand their range to northern remains unclear. Overwintering cold tolerance capacity largely ...
the leaf-miner fly, liriomyza sativae (blanchard), is one of the major insect pests of vegetable crops in iran and other countries. to determine the toxicity (lc50) of bioinsecticides abamectin 1.8% ec, cyromazine 75% wp and spinosad 24% sc against l. sativae, bioassay was done on its larval and adult stages under 25 â± 1â°c, 65 â± 5% r.h. and a photoperiod of 16: 8 (l: d). the lc50 values foun...
استفاده از ارقام مقاوم گیاهی به عنوان رهیافت موثر در مدیریت تلفیقی مگس مینوز BlanchardLiriomyza sativae مطرح است. در این مطالعه، مقاومت آنتی زنوزی 17 رقم خیار نسبت به مگس مینوز سبزیجات L. sativae در شرایط گلخانهای مورد ارزیابی قرار گرفت برای این منظور آزمایش غربال بر اساس بررسی شاخصهای تعداد نیش تغذیه ای، تعداد تونللاروی، نسبت تونل لاروی به نیش تغذیهای و میزان صدمه انجام شد. در آزمایش ...
Five species of black fungus gnats are recorded from Ukraine for the first time: Bradysia forficulata (Bezzi, 1914), B. lobata Hondru, 1968, normalis Frey, 1948, urticae Mohrig & Menzel, 1992 and Lycoriella sativae (Johannsen, 1912). Distributions these summarized their diagnoses provided.
In-vitro microbicidal activity of the methanol extract of Origanum majorana L. was tested against seven fungi (Fusarium solani, Candida albicans, Aspergillus niger, A. parasiticus, Rhizopus oryzae, Rhizoctonia otyzae-sativae and Altemaria brassicicola) and six bacteria (Bacillus subtilis, B. megaterium, Escherichia coil, Proteus vulgaris, Pseudomonas aeruginosa and Staphylococcus aureus). The m...
