Mustard aphid (Lipaphis erysimi) and English grain aphid (Sitobion avenae) are among the most important pests in mustard and wheat fields in Nepal.
Biocide Manic (Metarhizium anisopliae a.i. = 1 × 109 spores/ml) at 3 ml/l water, Agri Sakti (Beauveria bassiana a.i. = 1 × 109 spores/ml) at 3.3 ml/l water, Varunastra (Verticillium lecanii spores 2% aqueous suspension, 2 × 108 CFU/ml) at 6 ml/l water, Mahastra (Bacillus thuringiensis var.
kurstaki 0.5% wettable powder) at 6 g/l water, Neemraj Super (Azadirachitin 0.3% w/w) at 3.3 ml/l water, Tracer (Spinosad 90% spinosyns) at 0.33 ml/l water, and control treatment (pure water) were used to test their efficacy against L.
erysimi and S.
avenae, using leaf dip and spray methods under laboratory conditions in Rupandehi, Nepal, in the year 2018.
Each treatment was replicated four times, and the experiment was carried out in a randomized complete block design.
Mortality of aphids was recorded at 24, 48, 72, and 98 hours after treatment application.
The result revealed highest mortality of mustard aphids with Agri Sakti at 24 hours after treatment (HAT); however, Neemraj Super was found to be the most effective at 48, 72, and 96 HAT with the leaf spray method.
With the leaf dip method, Neemraj Super killed more mustard aphids than other treatments at all observed time points.
Among tested biorational products, Agri Sakti was found to be most effective against English grain aphids in both leaf spray and leaf dip methods.
In all the bioassays, the mortality caused by biorational compounds over control was highly significant.
The present study suggests for further verification of the biorational products in the field and development of novel management strategies against different species of aphids.
