The diploid number of a cell is the count of the number of chromosomes in that cell. In contrast, the haploid number is half the number of chromosomes, or the set of chromosomes donated by one parent.  The diploid number represents the total number of chromosomes donated by both parents.

Cells contributing to the structure of the mosquito's stomach are non-sex cells, and are therefore diploid, so the number of chromosomes would be 6.

Sperm cells, being gametes, are haploid, so the number of chromosomes present in a sperm cell is 3.

The number of chromosomes in each cell of the stomach would be 6 the diploid number.

The number of chromosomes in the sperm cell is 3 the haploid number.

the somatic or body cells of an organism undergo mitosis cell division in which the number of chromosomes remains same.whereas the sex cells undergo meiosis and the resulting sperms/eggs contain haploid number of chromosomes.

so,the stomach cells will contain the diploid number of chromosomes i.e: 6.

the sperm cells will contain haploid number of chromosomes i.e: 3.
