Title: Innovations of Ashok K Raina in Biological Control
Introduction
Ashok K Raina is a notable inventor based in Beltsville, MD (US). He has made significant contributions to the field of biological control, particularly in the management of pest populations. With a total of 5 patents, his work has paved the way for innovative solutions in pest management.
Latest Patents
One of Raina's latest patents focuses on the Formosan subterranean termite (FST). His research revealed that alates of the FST, collected after swarming in 2002, died within 48 hours and were visibly infected with a fungus. Fungi were isolated from the cadavers, leading to the identification of a single fungal isolate, C4-B, which was found to cause rapid mortality of FST alates. This discovery marks the first report of a biological control agent for termite alates. Strain C4-B demonstrated higher lethality compared to strain ESC1, which is marketed as the termite biocontrol agent BioBlast®. In field studies, 100% of FST alates exposed to C4-B spores were killed within three days, showcasing its effectiveness.
Another significant patent involves recombinant baculoviruses, which were prepared to express peptide hormones that inhibit feeding in Helicoverpa zea, commonly known as the corn earworm. The peptides, identified as helicokinins, lead to weight and water loss, ultimately resulting in the insect's death. This innovative approach highlights Raina's commitment to developing environmentally friendly pest control methods.
