Wheat is staple food of inhabitants of the Indian subcontinent and is grown all over the irrigated and rain fed areas of this region. This important crop is now under the threat of Karnal bunt disease caused by Tilletia indica; a fungus of basidiomycetes, that seriously affects the quality of the grains, by emitting fishy odour of tri-methylamine which makes the flour quality unacceptable for human consumption. Previously the disease was considered of minor importance and was prevalent in the areas of low temperature and high humidity only, but now it has got the status of emerging infectious quarantine disease in many parts of the world including Pakistan. Present studies were conducted to scrutinize the prevalence, infestation level of the infection and identification of genetic sources resistant to Tilletia indica pathogen. Studies were conducted in the wheat growing areas of the Southern Punjab that is under dry hot climate. Seven districts viz. Khanewal, Multan, Lodhran , Bahawalpur, Vehari, Bahawal Nagar and Rahim Yar Khan were selected to evaluate the disease as well as genotypes potential regarding the disease occurrence. During survey and monitoring of these localities forty nine hot spots of the karnal bunt disease were identified. Six high yielding commercial varieties were grown at these spots, out of which Punjnad-1 showed maximum capacity to resist the disease pressure followed by Inqilab-91. while Manthar -03 and Uqab- 2000.

A Comparative Review of Divorce in Islam and Judaism The theme of exchange among religions and similar investigation of religions has turned out to be significant in the current time. Many religious scholars have presented a comparative overview of the subject of many commandments and beliefs in religions, but the issue of divorce in Jews and Islam as a regular subject is almost never discussed. Although it is mentioned as an ancillary subject, such books were written on the topics of marriage and divorce in world religions. But question is, why is divorce comparative review important in Judaism and Islam? Because most of the believers in Islam and Judaism are based on their religious teachings and worried about the problem of rising numbers of divorces. According to the principles of comparative study the researchers have tried to do work on this topic in an objective manner. Finally, it has been concluded that the teachings of these two religions are in principle quite alike. While there is some disagreement on the side issues that open the door to mutual dialogue, it is possible that through comparative research on other topics between these two religions is conducted it will provide further avenues of dialogue and mutual understanding between two major revealed religious traditions.

Evaluation of Insecticidal Resistance in Mosquitoes under Controlled Conditions.

On an overall basis, fifteen species were recorded from four selected districts during 2016-17. However, populated area proved to more infested followed by agricultural and industrial area. Rawalpindi depicted as more diversified district as compared to Lahore, Sialkot and Faisalabad.A huge number of insecticides are used for the control of agricultural pests and household pests, such as mosquitoes, with the application of over and under doses in Punjab, Pakistan. Moreover, after the dengue epidemic that occurred during 2010, insecticides were sprayed in huge amounts and at high doses in major cities of Punjab to control mosquitoes. This also resulted in insecticidal resistance in mosquitoes. Mosquitocidal assays of larvae (in beakers) and adults (impregnated papers) were evaluated after 24 h. The bioassay data showed Temephos, Fenitrothion, Malathion, Pirimiphos Methyl, Cypermethrin, Deltamethrin, Permethrin and Bendiocarb lethal concentration (LC50) for 50 percent mortality of Ae. aegypti, Cx. quinquefasciatus and An. Stephensi susceptible population (SS) compared with field populations of Faisalabad (FSD), Sialkot (SKT), Rawalpindi (RWP) and Lahore (LHR). The larvicidal LC50 value of temephos ranged from 0.007 to 0.416 ppm. In the case of adulticides, three groups of insecticides were applied to papers and used against different populations collected from populated, agricultural and industrial areas of Lahore (LHR), Rawalpindi (RWP), Sialkot (SKT) and Faisalabad (FSD). Pyrethroids demonstrated the lowest effective concentration among the tested pesticides (organophosphates & carbamates). Among the pyrethroid group, deltamethrin was recorded as being the most toxic (0.483 – 9.245 ppm), followed by cypermethrin (1.839 – 33.139 ppm) and permethrin (5.145 – 101.533 ppm). ppm. The chi-squared value showed no heterogeneity across all the experiments. The results also indicated that the LHR population was highly resistant, followed by the RWP, SKT and FSD populations; moreover, the mosquito populations from agricultural areas were more resistant than those from populated and industrial areas. However, the resistance map also reflected that LHR showed extremely high to high level resistance which was indicated by red to blue color whereas RWP found high to moderate resistance indicated by blue to yellow followed by SKT and FSD. The biochemical analysis showed the elevated activity of enzymes (esterases, mixed-function oxidases, glutathione S-transferase and acetyl-cholinesterase) in resistant populations. It was concluded that the injudicious application of chemicals in an area caused the risk of resistance and the reappearance and resurgence of certain mosquitoes. Further, research is needed to identify health and environmental risks and to devise an effective programme through the use of selective and specific insecticides.
