Control experiments on Hylobitelus xiaoi with non-woven fabric band of Metarhizium anisopliae
By making of non-woven fabric band with the strain Ma1291-2 of Metarhizium anisopliae (Metsch. ) Sorokin and control experiment on Hylobitelus xiaoi Zhang in field, the results showed that the best inoculating concentration of making non-woven fabric bands with the strain Ma1291-2 was the ration of 1:3, and its, conidia production was (1.11 ±0.08) ×108 conidia · cm-2. Infecting test to H. xiaoi indoor with non-woven fabric bands, the correct mortality and cadaver rate of H. xiaoi were 64.25% and 62.25% respectively, and median lethal times (LT50 ) was 14.43 days. By controling experiments in field with non-woven fabric bands in two experimental plots, the control effect on H. xiaoi was (53.80 ±1.74)% and (51.54 ±1.35)% respectively, and the conidia in non-woven fabric bands kept 107 -108 conidia · cm-2 in 15 days, but sharply decreased after then. The spore germination rate was over 80% with less change in 30 days. It showed that non-woven fabric bands of the strain Ma1291-2 has a certain application value for controlling H. xiaoi.
