Temperature affects the tolerance of Liriomyza trifolii to insecticide abamectin

Cucurbitane glucosides from Momordica charantia leaves as oviposition deterrents to the leafminer, Liriomyza trifolii.

The American serpentine leaf mining fly, Liriomyza trifolii, whose larva feeds on more than 120 plant species is well characterized by its high degree of polyphagy. Observations on the oviposition behavior by L. trifolii demonstrated that among cucurbitaceous plants, Momordica charantia is rarely attacked by L. trifolii. The methanol extract of M. charantia leaves strongly deterred the females ...

A new oviposition deterrent to the leafminer, Liriomyza trifolii: cucurbitane glucoside from Momordica charantia.

A new cucurbitane glucoside, 23-O-beta-D-glucopyranosyl-7-hydroxy-3-O-malonylcucurbita-5,24-dien-19-al, named momordicine V, has been isolated from Momordica charantia leaves, along with the previously reported compounds, momordicines I, II, IV and 3-O-malonylmomordicine I. The structure of the new compound was established on the basis of spectral analysis, as well as by its conversion to momor...

Insecticide Use and the Ecology of Invasive Liriomyza Leafminer Management

Comparative toxicity of abamectin, cyromazine and spinosad against the leaf-miner fly, Liriomyza sativae (Dip.: Agromyzidae)

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...

Impact of Insecticides on Parasitoids of the Leafminer, Liriomyza trifolii, in Pepper in South Texas

Liriomyza leafminers (Diptera: Agromyzidae) are cosmopolitan, polyphagous pests of horticultural plants and many are resistant to insecticides. Producers in South Texas rely on insecticides as the primary management tool for leafminers, and several compounds are available. The objective of this study is to address the efficacy of these compounds for controlling Liriomyza while minimizing their ...
