| Abstract: | An investigation carried out in Lezhi,Sichuan showed that 5 species of peanut grubs werefound in the soil with Holotrichia parallela Motschulsky as the dominant species. In the growing seasonof the crop ,the grubs were primarily present in the top soil layer(0-10 cm),averaging 7. 05cm.At the harvesting time of the crop,the grubs were distributed deeper in the soil averaging 19.19 cm.The range of level moving of the grubs was in the range of 0-5cm and 0-3cm,respectively.Their population quantity gradually increased from A pril to July and then declined from July tonext March. |
