English Abstract

This study was carried out to determine the probable effects of crude alkaloid, phenolic, and terpenoide extracts of Albizzia lebbeck (L.)Benth, flowers, leaves, and seeds on some of the biological aspects of Musca domestica (L.) under laboratory conditions of 30±1 ◌ْC and 65±5 % relative humidity. The study was composed of five parts.

The first included treatment of egg stage.

The results showed a significant increase in egg mortality when they treated with 2.5, 5.0, 7.5, and 10 mg / ml of crude alkaloid, phenol, and terpenoid extracts of A.

lebbeck flowers, leaves, and seeds.

The alkaloids extract of flowers showed highest egg mortality rate at concentration of 10 mg / ml (90.0%) followed by alkaloid extract of leaves (83.6 %), then alkaloid extract of seeds (62.3%). The second part included effects of the extracts on larval instar mortality. The first larval instar was the most sensitive than the other larval instars. The mortality rate of first larval instar was 96.6%, 86.6%, and 70.0 % when treated with alkaloid extract of flowers, leaves, and seeds respectively at concentration of 10 mg / ml.

The mortality rate was 93.3%, 76.6%, and 60.0 % respectively in the second larval instar, and 83.3%, 70.3%, and 60.0 % in the third larval instar at the same plant parts and concentration.

When treated with phenol extract, the mortality rate of 1st larval instar reached 90.3%, 86.6%, and 63.3 %.

While it was 86.6, 80.0, and 60.0 % in the 2nd larval instar, and 83.3%, 73.3%, and 56.6 in 3rd larval instar at the same plant parts and concentration.

However treated with terpenoide extract the mortality rate was 80.3%, 73.3%, and 46.6 % in the 1st larval instar, while it was 76.6%, 70.0%, and 40.3 % in 2nd larval instar , also it reached 66.6%, 66.6%, and 33.3 % in 3rd larval instar, at the same plant parts and concentration. The third part included the effects of A.

lebbeck extracts on M.

domestica pupae.

Pupal mortality rate was 66.6%, 56.6%, and 43.3 % at concentration of 10 mg / ml when treated with alkaloid extract of flowers, leaves, and seeds respectively.

While it reached 63.3%, 60.3%, and 36.6 % when treated with phenol extract of flowers, leaves, and seeds respectively at the same concentration, also the mortality rates were 40.0%, 43.3%, and 30.0 % when treated with terpenoid extract for the same plant parts and concentration above. The fourth part included the effects on the developmental period of immature stages of M.

domestica.

The results showed an increase in developmental period of immature stages of M.

domestica that treated with different concentrations of A.

lebbeck extracts.

It was 18.5, 17.3, and 15.0 days when treated with alkaloid extract of flowers, leaves, and seeds respectively at concentration of 10 mg / ml.

While it was 17.7, 16.1, and 14.3 days when treated with phenol extract at the same plant parts and concentration above.

However, it was 15.8, 14.6, and 14.1 days when treated with terpenoid extract at the same plant parts and concentration mentioned above.

Compared with control treatments which ranged between 10.0-10.3 days. Results of present study indicated that 10 mg / ml concentration of A. lebbeck extracts led to decrease females productivity.

Eggs production of adult females treated with alkaloid extract of flowers, leaves, and seeds were 0.0 egg / female, compared with 128.0, 138.0, and 126.0 egg / female at control treatments .

Also the eggs productivity were 0.0, 0.0 and 26.0 eggs / female when treated with phenol extract of flowers, leaves and seeds respectivly, compared with control treatments which were 118.3, 128.6, and 122.0 eggs/female respectivily.

The female productivity was 0.0 egg / female when treated with terpenoid extract of flowers, and leaves, compared with control treatments which were 136.3 and 126.0 eggs / female.

While, they were 30.0 eggs / female when treated with terpenoid extract of seeds compared with control treatment which was 137.3 eggs / female at the above mentioned concentration.
