  • The Effect of Various Plant Products on Mosquitoes Larvae Anopheles arabiensis and Culex quinquefasciatus (Diptera: Culicidae)

This research aimed to study the larvicidal potentialities of three different local poisonous
plants: ward elhameer N, ushar U and castor oil R (using different parts) leaves L, flowers
F and seed S) against two important species of mosquitoes (Anopheles arabiensis and
Culex quinquefasciatus), by using two different methods of application (powder P and
aqueous extract aq-ex), The standard methods of WHO for rearing and assessment of
mosquitos' susceptibility were carefully followed. The results revealed that, for
Anopheles larvae, and according to the LD50 values, the products can be ranked from the
more potent toward the least potent ones as follows: RS, NL, UL, NF and lastly UFo The
potentiality arrangement for Culex larvae are as follows: RS, UL, NL, NF and lastly UFo

  • Effect of Aqueous Extract of Cathedral Cactus (Euphorbia trigona Mill) on Larvae of Anopheles arabiensis (Diptera: Culicidae)

Mosquitoes are considered as vector of malaria disease and some other endemic diseases
in the world. There are some methods already been used for controlling mosquito; of
which is using natural products. This study was conducted at Laboratories of Faculty of
Engineering and Technology, University of Gezira, to evaluate the effect of cortex, spine
and pith parts of cactus (Euphorbia trigona) on Anopheles mosquito larvae. The plant
parts were collected from Wad Medani City, whereas, the mosquito larvae were collected
from the breeding sites at Tayba village, Gezira State, Sudan. The plant parts (cortex,
spines and pith) were shade dried away from the direct sunlight, grounded and then kept
separately in small plastic sacks. From each plant part, a concentration of 1200 mg/L was
used. The standards of WHO for testing toxicity of the toxic compound against mosquito
larvae was followed. The mortality in Anopheles larvae were 48%, 37% and 62%,
respectively, for trigona cortex, spine and pith. The results also showed that, the three
used parts have a varied great impact on the survived larvae (morphological changes of
skin color was in 82%, disconnecting of digestive tract was in 48%, and separation of
some body parts was in 32%, after 48 hours of applying it). The study recommends
adding these cactus parts as potential natural products for Anopheles larval control, and
also running more sensitive tests to measure the environmental impact of these products,
especially on human and on the aquatic fauna.

  • THE EFFECTS OF AQUEOUS EXTRACT HIBISCUS SABDARIFFA ON SPERMATOGENESIS AND SPERM PARAMETERS OF MICE

This study was aim to evaluate the effect of aqueous fruit extract of Hibiscus sabdariffa Linn on spermatogenesis and sperm of mice. Adult male mice (n=30) included in the present study. The mice were eight weeks old and their average weight was 28±3g. Male mice housed in temperature controlled rooms (25°C) with constant humidity (40-70%) and 12h/12h light/ dark cycle according experimental protocols. Thereafter, the mice were randomly divided into control (n=10) and experimental group (n=20). The control group received daily 8 ml distilled water, group-1 of the experimental group received 50 gm/Kg/BW and group-2 received 100 gm/Kg/BW of aqueous extract of Hibiscus sabdariffa. The experiment extended for 21 days. The results of this study showed that there was an increase in the average body weight in the experimental groups compared with the control group with a significant difference (p<0.05). While the testis weight, sperm counts, sperm motility and viability decreased in the experimental groups compared with the control group with a significant difference (p<0.05). The effect of Hibiscus sabdariffa on Sex hormones the study showed that there was significant different (p> 0.05) in FSH; LH and testosterone hormones when compared with control In study of testis histology showed a significant decrease in the lumina spermatozoa. The study concluded that Hibiscus sabdariffa has adverse effect on spermatogenesis and sperm parameters of mice. Keywords: Aqueous, Hibiscus sabdariffa, spermatogenesis, sperm parameters, mice
