Introduction Urbanization is the replacement of nature by culture.

Many habitats have been lost and a few new onesgained (Helden and Leather 2004). Insects became

pest or nuisance. House promotes the breeding site for Insects.

Insects around the house: mosquitoes, houseflies,

termites, ants, mites, cockroaches and etc. Insects carry and transmit diseases.

Literature Review

Many factors have been influenced in determining therelative species richness of different urban habitats

and habitat patches (Helden and Leather 2004). The factors are the level of isolation and

fragmentation, disturbance, habitat type, area anddiversity (Connor et al., 2003)

Objectives of Study To determine the species diversity of insects in indoor

and outdoor the house.

To use the variable method to collect the insects anddetermine the suitable method according to thehabitats.

Statistical Analysis The big questions is to want to know the abundance

(number) of insects due to the different

1) Study sites: Indoor-Indoor, Indoor Outdoor, Outdoor Outdoor.

2) Time of sampling: Morning Night

3) Type of sampling method: Baiting, Pitfall, Light trap,Sticky Trap.

Expected Result Expected species will be collected:

Indoor vs Outdoor: Outdoor >Indoor (no of species).

Day vs Night: Diurnal and Nocturnal species. Method of sampling: Light trap may be the most

practical method (outdoor) and baiting (indoor) tocollect the diversity species of insects.
