The insecticidal potential of chilli pepper extracts against musca domestica / Nurul Ain Zulkifli

Musca domestica (Diptera: Mucidae) also known as housefly and has four stages
of life cycle which are eggs, larval, pupal and adult stages. Housefly is a known
vector for various diseases and is controlled by using chemical-based insecticide.
Chemical-based insecticide gives harm human's health. Therefore, the objectives
this research are to study the life cycle and the characteristics of Musca domestica,
to investigate the effect of Capsicum spp. crude extracts towards houseflies and also
to compare the effectiveness of Capsicum spp. as bioinsecticide. The wild
houseflies were captured in plastic container and cultured in food media for two
weeks. The life cycle of cultured houseflies completed in four stages which were
eggs, larvae, pupae and adults within two weeks. The comparison between sex can
be determined by their size and the distance between houseflies' eyes. The crude
extract Capsicum sp. 1 and Capsicum sp. 2 were prepared for treatment towards
houseflies along with negative control which was distilled water and positive
control which was malathion. The behaviour of the houseflies after exposed to both
Capsicum spp. and malathion solutions was positive such as lied on the surface of
the surface of the container and their wings vibrate in pulse compared to distilled
water. The mortality rate for Capsicum sp. 1 and malathion is 100 % while
Capsicum sp. 2 was 77.8%. Capsicum spp. provide an alternative method for
controlling houseflies as it contains natural compound such as capsaicin which have
the ability to act as natural insecticide.
