Thin Malpighian tubules in cockroach are present at the junction of
1 Foregut and midgut
2 Midgut and hepatic caecae
3 Foregut and hindgut
4 Midgut and hindgut
Explanation:
At the junction of midgut and hindgut ring of 100-150 yellow coloured thin filamentous Malpighian tubules are present. They help in removal of excretory products from haemolymph.

In which of the following structure in the cockroach six highly chitinous teeth are present?
1 Crop
2 Proventriculus
3 Intestine
4 Oesophagus
Explanation:
Gizzard or proventriculus has an outer layer of thick circular muscles and thick inner cuticle forming six highly chitinous plate called teeth. Gizzard helps in grinding the food particles.

Mark the corret statement for cockroach
1 1 oviduct unites to form single median oviduct
2 Spermatophore is the bundle of eggs discharged during copulation
3 Each ootheca has 4 to 6 eggs
4 Its development paurometabolous
Explanation:
The development of P. americana is paurometabolous, meaning there is development through nymphal stage. The nymphs look very much like adults. The nymph grows by moulting about 13 times to reach the adult form.

The nervous system of cockroach; what is true?
1 Brain in the ventral region
2 It is represented by segmentally arranged ganglia forming ventral nerve cord
3 It is not spread throughout the body
4 Consists of a series of unfused, segmentally arranged ganglia joined by single longitudinal connectives
Explanation:
The nervous system of cockroach consists of a series of fused, segmentally arranged ganglia joined by paired longitudinal connectives on the ventral side.
