Green lacewing, Chrysoperla carnea (Steph.), is one of the important natural enemies of cotton aphid, Aphis gossypii Glover. In this study, two experiments were conducted on cucumber plant in netted cages (70*70*40 cm) in a greenhouse. In the first experiment, Chryso-bags (special net bags with 360 holes per 2.5 cm2 and 8 cm in width and 12 cm in length) were used. Seven treatments of release r...

Beech sawdust was reacted with phthalic (PA) and maleic (MA) anhydrides for chemical modification. The influence of reaction time and anhydride amount was investigated. IR spectra gave evidence of wood esterification. Thermogravimetric investigation of chemically modified wood indicated a better thermal stability (mainly for wood treated with phthalic anhydride) in comparison with the untreated...

Torrefaction tests on miscanthus and white oak sawdust were conducted in a bubbling sand bed reactor to see the effect of temperature and residence time on the chemical composition. Process conditions for miscanthus and white oak sawdust were 250–350 °C for 30–120 min and 220–270 °C for 30 min, respectively. Torrefaction of miscanthus at 250 °C and a residence time of 30 min resulted in a signi...

The lignin-first biorefinery strategy could produce bio-based phenols from the extraction and depolymerization of native lignin in lignocellulosic biomass. Herein, we report an effective Lewis acid-promoted delignification production monophenolic compounds birch sawdust assisted by microwave heating without external hydrogen for first time. screening different metal triflates revealed that Fe(O...
