Function of Ampulla of Spermatheca:
The ampulla of spermatheca is an important structure found in the female reproductive system of insects, particularly in bees and some other insects that engage in multiple mating. Its main function is to store and nourish sperm received during copulation.
Here is a detailed explanation of the function of the ampulla of spermatheca:
1. Sperm Storage: The primary function of the ampulla of spermatheca is to store sperm received from the male during mating. This storage is crucial for ensuring fertilization of eggs over an extended period.
2. Sperm Nourishment: The ampulla of spermatheca provides nourishment to stored sperm, ensuring their viability and functionality until they are used for fertilization. The nourishment includes the secretion of substances that provide energy and protect the sperm from degradation.
3. Sperm Selection: The ampulla of spermatheca also plays a role in selecting and retaining sperm from preferred males. It allows the female to choose the most genetically compatible sperm for fertilization, increasing the chances of successful reproduction.
4. Delayed Fertilization: In some species, the ampulla of spermatheca allows for delayed fertilization. This means that the female can store sperm for an extended period before using it to fertilize eggs. This adaptation is advantageous when mating opportunities are limited or when females need to delay reproduction for optimal conditions.
5. Preventing Multiple Mating: In species where females mate with multiple males, the ampulla of spermatheca aids in preventing multiple matings by ensuring that sperm from the last male to mate is used for fertilization. This helps to avoid sperm competition and ensures the reproductive success of the most recent mating partner.
In conclusion, the ampulla of spermatheca functions to store and nourish sperm, select genetically compatible sperm, allow for delayed fertilization, and prevent multiple matings. It is an essential structure in the reproductive process of insects and contributes to the successful reproduction of the female.

The purpose of spermatheca is to receive and store sperm from the male or, in the case of hermaphrodites, the male component of the body. The sperms stored in the spermatheca is nourished by ampulla.
So, the correct answer is 'To nourish sperms'.
