Efficacy of Phytoseiulus Persimilis Athias-Henriot
(Acari: Phytoseiidae) on the two Spotted Spider
Mite Tetranychus Urticae Koch (Acari:
Tetranychidae). J. Bio-Sci., 2007, 15, 127-132.
The relative abundance Tetranychus urticae and
Phytoseiulus persimilis as well as voracity of the
predator were conducted on potted eggplants. After
six weeks of release of ten female T. urticae in
control plants, the highest mite population reached
at 184.21/ leaf, against 67.92 and 107.48/ leaf in
st
plants which received two predators after 1 and
rd
3 week respectively. After nine weeks the number
of mite / leaf reduced to 13.21 and 23.97 / leaf
rd
st
after 1 and 3 week of introduction of the
predator, the control population was 81.32. Adult
P. persimilis as single predator fed 8.2, 15.4 and
20.6 T. urticae eggs after 24, 48 and 72 h
respectively. Again a single predator when tested
separately fed 5.4, 10.8 and 14.6 T. urticae larvae
after 24, 48 and 72 h respectively. A single adult
predator fed on 3.6, 7.0 and 12.0 adult T. urticae
135
(10, 20, 30, 40 and 50) of prey (larvae or adults)
were provided to a single predator it fed 5.0, 6.6,
6.8, 9.0 and 9.4 larvae against 3.2, 3.2,3.4,3.6 and
3.6 adults respectively.

(BCSIR Laboratories, Chittagong). Anti-inflammatory,
analgesic and antipyretic activities of ethanol leaf
extract of Chromolaena odorata (L.) R. M. King &
H. Robinson. Bang. J. Life Sci., 2008, 20 (2), 87-
93.
The present study was carried out to investigate the
Anti-inflammatory, analgesic and antipyretic
activities of the ethanol leaf extract of
Chromolaena odorata on experimental animal
model at the dose of 1g/kg body weight. Two well
established model carrageenan induced paw edema
and cotton pellet induced granuloma formation
were used for evaluating anti-inflammatory
property. Analgesic activity was assessed in mice
using acetic acid induced writhing response.
Antipyretic activily was also investigated on yeast-
induced pyrexia in rats. Acute toxicity test was
performed in rats after administration of the extract
orally at high dose level (4g/kg). Oral
administralion of the ethanol extract of
Chromolaena odorata significantly (P<0.01)
suppressed the paw edema induced by carrageenan
as well as granulomatous tissue formation induced
by cotton pellet in rats successfully. In addition, an
appreciable antipyretic effect was also noticed with
ethanol extract but no significant analgesic activity
was observed. In acute loxicity study, no mortality
was observed at 4 g/kg dose level. The present
study demonstrates the potential anti-inflammatory
and antipyretic effect of the ethanol leaf extract of
Chromolaena odorata, which supports the claims
by the traditional medicine practioners.
