2. Platygaster oryzae i s a parasitic wasp that targets rice pests, particularly the rice gall midge. Mass production of Platygaster oryzae can be essential for biological pest control in rice fields.

3. Selection of Host Insects: Platygaster oryzae parasitizes rice stem borers. The host insects should be collected and maintained in the laboratory for the wasps to parasitize. Rearing Conditions: The laboratory conditions should mimic the natural habitat of Platygaster oryzae . This includes temperature, humidity, and light cycles that are suitable for their growth and development. Mass Production of Platygaster oryzae

4. 3. Mass Rearing of Platygaster oryzae : Once the host insects are available, the parasitic wasps can be introduced to them for oviposition . The eggs laid by the wasps will hatch into larvae that will parasitize the host insects. 4.Feeding and Maintenance: Proper nutrition for both the host insects and the parasitic wasps is crucial for their development. Providing a suitable diet and maintaining hygiene in the rearing environment is essential.

5. 5. Monitoring and Quality Control: Regular monitoring of the rearing process is necessary to ensure the health and quality of the parasitic wasps. Quality control measures should be in place to maintain the effectiveness of the biological control strategy. 6. Release in the Field: Once an adequate number of Platygaster oryzae have been mass-produced, they can be released in rice fields to control the population of rice gall midge .

6. By following these steps and ensuring proper care and conditions for mass production, Platygaster oryzae can be effectively utilized for biological pest control in rice fields.
