The experiment was conducted at Sericulture Research Unit, VNMKV, Parbhani, during year 2024-25 in completely randomized design with six treatments and four replications for the objective of parasitization. During the study, the months from October 2024 to March 2025 were utilized as treatments. The main objective was to assess the monthly parasitization efficiency of Nesolynx thymus on both Musca domestica and Exorista bombycis pupae.

The study focused on the parasitization potential of Nesolynx thymus against Musca domestica and Exorista bombycis pupae over a six-month period. The pupae showed the highest parasitization rates during the cooler months of November and December. In these months over 90% parasitization was recorded which indicated peak activity. The month January also showed high parasitization while moderate results were observed in October. However, there was a gradual decline in parasitization from February onward with the lowest rates recorded in March. This trend suggests that N. thymus is most effective in cooler and more humid conditions while higher temperatures may reduce its parasitic efficiency.

Overall the findings from this study provide important insights into the performance of Nesolynx thymus as a biological control agent. These results can be utilized in planning timely pest management strategies in sericulture particularly by focusing the use of N. thymus during its peak effectiveness period from November to January.
