Paddy rice brown paddy plant hopper screening---the quantitative spray method of petridish seedling worm
The paddy rice seedling is fixed in the petridish with white quartz sand, connects and use CO 2Anaesthetize 3 mid-term in age nymph, place under the POTTER spray tower spraying.The spraying back covers with the transparent plastics cup, is put in the observation ward behind the mark.Test repetition 4 times.Check result behind the 72h.Touch polypide with writing brush, reactionlessly be regarded as dead worm.With SD-1750 and blank CK is contrast.
The mythimna separata screening---soak the seedling feeding method
Leaf of Semen Maydis is fully soaked into the back dry in the shade naturally in soup, put into petridish, connect 3 mid-term in age larva, add a cover mark and be placed in the observation ward.Test repetition 4 times.Check result behind the 72h.Touch polypide with writing brush, reactionlessly be regarded as dead worm.With SD-1750 and blank CK is contrast.
Carmine spider mite screening---pickling process
The broad bean blade is broken into the leaf dish, and the back side is placed on the fritter cotton up, places in the plastic culture dish, adds less water, connects carmine spider mite and becomes mite.Treat into mite after stablizing on the blade, blade is fully inhaled defoliation sheet surface water droplet with thieving paper rapidly behind the infiltration 5s in soup, place again on the cotton, air-dry.Test repetition 4 times.Check result behind the 72h.With pyridaben and blank CK is contrast.
Aphis craccivora screening---pickling process
If the broad bean blade is cut off two ends, and the back side is placed on the fritter cotton up, places in the plastic culture dish, adds less water, connects aphis craccivora and becomes aphid to produce aphid.Remove into aphid behind the 24h, continue behind the cultivation 2d blade behind the abundant 5s of infiltration, to be placed on the cotton natural airing again in soup.Check result behind the 24h.With carbosulfan and blank CK is contrast.
Test statistics with advance the sieve standard:
Add up the dead borer population and the borer population of living of each processing, the calculating mortality ratio (Abbott ' the s formula).
