Eco-friendly Management of Mustard Sawfly Athalia lugens proxima (Klug) on Asalio (Lepidium sativum)

Abstract

The present research was under taken on the mansagement of mustard sawfly, Atthalia lugens proxima (Klug) on Asalio, Lepidium sativum. Athalia lugens proxima (Klug) (Hymenoptera, Tenthredinidae) commonly known as mustard sawfly is a major pest of mustard. Seeds are used for recovery of chronic brochial asthma and enhancing milk yield in both animals and human beings. The field experiment was conducted with eight treatments and three replications with plot size of 3 m x 4 m with design RBD. The experiment was conducted during three years 2020-21 to 2022-23 during peak pest infestation on the crop Asalio, Lepidium sativum (Rabi season) at Central Campus, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar, Maharashtra. The pooled results of three years data i.e. 2020-21, 2021-22 and 2022-23 presented in the Table 1. Observations on pre count was recorded and the pooled mean was ranged from 7.55 larvae per plant to 7.68 larvae per plant. Subsequently the observations were recorded at 3, 7 and 14 days after sprayings. From the three years pooled data, it was concluded that among all treatment tested the treatment Beauveria bassiana @ 5 g/lit was found statistically significant with minimum survival of larval pest population i.e. 2.66 larvae/plant after first spray and 0.91 larvae/plant after second spray with maximum seed yield 16.10 q/ha and maximum ICBR i.e. 1:12.17 and B:C ratio 2.13.
