  • Evaluation of the efficacy of different extracts of Gumbail parts (Cordia africana Lam.) for termite control

Gumbail tree is of wide distribution in forests of Sudan, and has many important uses. The aim of this study was to evaluate the effect of extracts of leaves, bark and root of Gumbail (Cordia africana Lam.) to control Termite attacking. The extracts of plant substances with different concentrations were separately sprees on a three layers of cellulose pads to assay for their efficiency as anti-termite or termite repellency using the grave yard method. It was observed that, all ethyl acetate of leaves, bark and root have significantly reduced Termite’s infestation as compared to other extracts. Further analysis showed that, all concentrations for different extract solvents significantly reduce termite attack compared to the untreated control. The ethyl acetate leaves extract had significantly higher anti-termite activity compared to the control and other test solvents, and it resulted in mean of (17.26% weight loss). The study proved the suitability of leaves ethyl acetate extract of Gumbail for controlling termites, and represents a good environmental and alternative method for synthetic insecticides of termites.

  • Damage caused by castor seed oil and its ethanol extracts on Anopheles arabiensis Larvae, Gezira State, Sudan

Anopheles 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 natural products. This study was conducted at Laboratories of Faculty of Engineering and Technology, University of Gezira, to evaluate the damage caused by Castor seed raw-oil and its ethanol extract on Anopheles arabiensis mosquito larvae. The Castor seeds were collected from Wad Medani City, whereas, the mosquito larvae were collected from the breeding sites at Tayba village, Gezira State, Sudan. The Castor seeds were shade dried away from the direct sunlight, grounded and then kept separately in small plastic sacks. The raw oil (extracted from the castor seeds) was applied at a concentration of 1.67 ml/L (0.50 ml oil/ 300 ml water) while its ethanol extract was applied at concentration of 30.53 mg/L. The standards of WHO for testing the toxic compound against mosquito larvae was followed. The mortality in A. arabiensis larvae were 95% and 100%, respectively, for the ethanol extract and raw oil, after 24 hours. The results also showed the damage caused by each treatment on the dead larvae and on the survived larvae. The damage involved changes in skin color, formation of larval-pupal intermediate form, swelling, separation in digestive tract, separation of body hairs and decapitation. The study recommends adding these castor seeds as potential natural products for Anopheles larval control, and also running more sensitive tests on human, environmental resources and on the aquatic fauna

  • 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.
