Abstract:
... We established a method for mass-rearing the stone leek leafminer, Liriomyza chinensis (Kato) (Diptera: Agromyzidae), one of the most destructive pests of Welsh onion, Allium fistulosum L. We examined three methods that allow L. chinensis to produce eggs year-round. By recording the number of emerged adults for 4 years, we determined the optimal mass-rearing method as follows. Allium fistulosum pl ...

Three matrices (tomato, orange, and leek) and 163 pesticides were used for this study. Samples were analysed by use of 1, 5, 8, and 20 mass windows and the last one was used only in the QToF. The objectives of the evaluation were: the nu ...

However, some practical aspects of the implementation of these sensors remain poorly understood. We studied an optimal measurement setup combining both sensors for disease detection in leek and potato. This was achieved by optimising the signal-to-noise ratio (SNR) based on the height ...

We investigated virus infection rates in Japanese garlic plants and found that a potyvirus, onion yellow dwarf virus (OYDV) was always associated with another potyvirus, leek yellow stripe virus (LYSV). When the OYDV HC-Pro genes from those viral isolates were PCR-amplified and sequenced, we found that all the HC-Pros isolated from Japanese garlic lacked a long stretch of the N-terminal amino acid ...

Abstract:
... Evaluation of chiral pesticides remains a frequently neglected matter in routine food control laboratories. This fact is due to the existence of many residue definitions but also due to the lack of robust instrumental methods for the evaluation of these isomeric compounds. However, supercritical fluid chromatography coupled to mass spectrometry (SFC-ESI-MS/MS) has been demonstrated to perform fast ...

This phytoparasitic nematode species has a very narrow host range and causes severe crop losses in the main carrot‐growing regions worldwide. The development of alternative means of management of H. carotae is thus essential, and knowledge is requi ...
