- 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 ...

- Abstract:
- ... Two high-resolution instruments (a QToF and a QOrbitrap) were used to evaluate a segmented non-target MS2 (SWATH/vDIA) acquisition for pesticide residue analysis. 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 ...

- Abstract:
- ... The stone leek leafminer, Liriomyza chinensis (Kato) (Diptera: Agromyzidae) , is recognized as one of the most destructive pests of the bunching onion. Varietal resistance against L. chinensis has been reported in Allium fistulosum in Japan. We report a new method for evaluating the antibiosis of bunching onions with varietal resistance to L. chinensis by artificially inoculating leaves with L. ch ...

- Abstract:
- ... Onion thrips, Thrips tabaci Lindeman, 1889 (Thysanoptera: Thripidae) has three distinctive reproductive modes: arrhenotokous, thelytokous and deuterotokous. This experiment was focused on the arrhenotokous leek-(L1) and tobacco-associated (T) T. tabaci lineages. These two lineages are distinctively varied genetically and in host adaptations. L1 and T lineages perform better on leek and tobacco pla ...

- Abstract:

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 ...

A fast and sensitive analytical method would aid monitoring imidacloprid residues. The monoclonal antibody 4D9, colloidal gold and time-resolved fluorescent nanobeads (CGN and TRFN, respectively) were applied to develop a lateral flow immunoassay (LFIA) ...

Ecological intensification of farming proposes that more effective use of ecosystem services can, in part, replace external inputs allowing farmers to maintain high crop yields while reducing adverse effects on the environment. However, uptake of ecological intensification among farmers is currently hampered by a lack of realistic studies on the agronomic benefits of enhancing ecosystem services v ...

- Abstract:

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 ...

A survey was undertaken in Antovotany-Ambohijanaka, Region of Analamanga in order to answer to the following question: “What is the farmer's logic in their choice of cultivated vegetable and in the varietal choice as well?” The results show that the chosen culture is not the same for all farmers. Each farmer family adopts in average 6 speculations. However, it has been reported that leek (Allium p ...

Arbuscular mycorrhizae increase the efficiency of chemical fertilizers applied to crops, and this work is part of this framework. NPK (nitrogen-phosphorus-potassium) was applied at 100 kg per ha and 200 kg per ha alone or in combination with inoculum from sorghum or leek in soil (pH 4.28). The trial was conducted ...
