Pollen Viability and Autogamy Fitness in Bauhinia forficata Link (Fabaceae)

Floresta e Ambiente, 2018
Bauhinia forficata (Fabaceae) occurs in many phytophysiognomies of southern Brazil, however its ecological relevance is not well understood. The present study was developed in the Central Depression of Rio Grande do Sul and aimed to determine variations ...

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

Pest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.)

Pest Management Science, EarlyView.
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major

The biological value of pollen of some blackcurrantcultivars (Ribes nigrum L.)

Acta Agrobotanica, 2012
The studies were carried out in 1994-1997. The experimental bushes were grown in Puławy. Eight cultivars were examined ('Ben Alder', 'Ben Lomond', 'Ben Nevis', 'Ben Tirran', 'Ceres', 'Ojebyn', 'Titania', 'Triton').

Dose‐dependent efficacy of a novel dsRNA‐based solution containing vadescana for Varroa destructor control

Pest Management Science, EarlyView.
Vadescana is a novel dsRNA‐based product that targets Varroa fecundity. Vadescana applied at 4 g/brood box in one application was most effective at reducing Varroa populations for up to 18 weeks. Abstract BACKGROUND A novel dsRNA‐based product, containing a molecule called vadescana, interferes with Varroa destructor (Anderson and Trueman) fecundity ...

Pro‐197 mutations confer resistance to thiencarbazone but not to foramsulfuron in ALS‐resistant Poa annua populations

Pest Management Science, EarlyView.
Foramsulfuron remains effective on Pro‐197 Poa annua, but co‐formulation with thiencarbazone reduces efficacy due to limited activity and antagonism. Therefore, foramsulfuron + thiencarbazone should be used in fields without ALS‐resistant weeds to ensure effective in‐crop control.

Effects of elevated CO2 and temperature on cocklebur (Xanthium strumarium L.) and its herbicide response

Pest Management Science, EarlyView.
Elevated CO2 promotes the growth of Xanthium strumarium while increasing its susceptibility to the systemic herbicide trifloxysulfuron‐sodium. The efficacy of the soil‐active herbicide fluometuron remains unaffected by changes in CO2 concentration and temperature.

Intercropping mitigates incidence of the oilseed rape insect pest complex

Pest Management Science, EarlyView.
Intercropping reduces the incidence of the oilseed rape insect pest complex with a significant impact of the direct visual and physical disruption provided by the companion plant. Abstract BACKGROUND Oilseed rape (OSR, Brassica napus) is a major crop requiring numerous phytosanitary treatments.
