← Nature & AnimalsWhich consequence results when a parasitoid wasp injects polydnavirus into a lepidopteran pupae?
A)Host immune suppression via gene insertion✓
B)Accelerated pupation causing premature emergence
C)Enhanced hemolymph coagulation blocking parasitoid
D)Increased melanin production forming melanotic capsule
💡 Explanation
When polydnavirus is injected, viral genes are inserted into the host cells leading to the expression of proteins that suppress the immune system because the wasp requires undeveloped host. Therefore immune suppression results, rather than premature changes, coagulation or melanotic encapsulation which rely on different physiological defenses being activated.
