the beet armyworm spodoptera exigua (hübner) is a serious and economically important pest of solanaceous crops worldwide. the nutritional indices of this pest on three host plants including pepper capsicum frutescens, eggplant solanum melongena and tomato solanum lycopersicum were determined under laboratory conditions at 26 ± 1 °c, 60 ± 5% rh and 16: 8 (l: d) h. the highest relative consumptio...

The colonial hydroid Podocoryna carnea grows adherent to surfaces progressing along them by a motile stolon tip. We here ask whether the stolon tip grows preferentially within grooves etched in silicon wafers. In a series of pilot experiments, we varied the dimensions of grooves and found that stolons did not utilize grooves with a width:depth of 5:5 μm or 10:10 μm, occasionally followed groove...
