Reproductive system
in insects
,• Male and female sexes are mostly separate
• Sexual dimorphism is common - male differ from the
female morphologically
Eg: bees, mosquito and cockroach
The other types are:
Gynandromorph: (Sexual mosaic)
• Abnormal individual with secondary sexual characters of
both male and female
e.g. mutant Drosophila
Hermaphrodite:
• Male and female gonads are present in one organism.
e.g. Cottony cushion scale.

Female reproductive system
Male reproductive system
1.Paired ovaries composed of
1.Paired testes composed ovarioles (egg tubes)

2. Paired vasa differentia 2.Paired oviducts
3. Median ejaculatory duct 3.Median oviduct
4. Accessory glands 4.Accessory glands and Colleterial
glands
Spermatheca (sperm pouch)
Bursa copulatrix
(copulatory pouch)
