Current study was conducted at research area of Department of Entomology, Agriculture University, Peshawar, Khyber Pukthunkhwa during spring 2013. The purpose of study was to investigate the comparative resistance of tobacco cultivars and efficacy of Bifenthrin at various concentrations (0.08%, 0.125%, 0.166%, and 0.208% and control) against major insect pests of tobacco. The concentrations of insecticide differed significantly in term of controlling the cutworm, budworm and aphids infestation. The 0.166% and 0.08% concentration of Bifenthrin found most effective in controlling the cutworm and budworm infestation (1.2 and 8.2 percent, respectively). For checking the aphid population, the 0.208% concentration of Bifenthrin remained most suitable. The lowest infestation (29.1) of said insects was noticed on cultivar PVH- 2310. Cultivars behaved differently for the studied traits but not for insecticidal concentrations. For nicotine contents the response of cultivars was non- significant. Results regarding the percent budworm damage revealed that PVH2310 was the most resistant cultivar (7.7%) and 0.08% concentration of Bifenthrin showed most effective control (8.2%) seven days after the application of spray (5.0%).
本研究于2013年春季在开伯尔普克图赫瓦省白沙瓦农业大学昆虫学系研究区进行。研究不同浓度(0.08%、0.125%、0.166%、0.208%和对照)联苯菊酯对烟草主要害虫的抗性比较及防治效果。不同浓度的杀虫剂对棉铃虫、budworm和蚜虫的防治效果有显著差异。联苯菊酯浓度为0.166%和0.08%时,对蛴螬的防治效果最好(分别为1.2%和8.2%)。以联苯菊酯浓度为0.208%为最适宜。品种PVH- 2310的侵染率最低,为29.1。不同品种对所研究性状表现不同,但对杀虫浓度表现无差异。不同品种对烟碱含量的反应不显著。结果表明,PVH2310对虫害率最高(7.7%),0.08%浓度的联苯菊酯对虫害率最高(5.0%)。

CERES-WHEAT Model is an important technique to assess growth, development and radiation use efficiency skills of wheat crop. Under changing climatic conditions world over, one of the suitable approach is needed to enhance the growth and reproductive skills of field crops. For the purpose, a field trial was conducted at Adoptive Research Farm Sargodha. The study comprised of four fertilizer levels viz. control (Recommended dose), 84, 114, 144 kg ha -1 and three irrigation levels viz. irrigation at crown root + jointing + milking, at crown root + booting + grain filling, and at jointing + booting + grain filling. Irrigation levels were kept in main plots and fertilizer levels were randomized in subplots. Data revealed that Crop Growth Rate (CGR), Leaf Area Index (LAI), Leaf Area Duration (LAD) and Net Assimilation Rate (NAR) were significantly increased by increasing the fertilizer levels as well as irrigation frequency. Maximum grain yield 5528 kg ha -1 was obtained while irrigating the crop at jointing + booting + grain filling stages using 144 kg ha -1 of nitrogen. Interestingly, increase in fertilizer rate increased the yield and yield components and plant growth and radiation use efficiency. In conclusion, three irrigations at jointing + booting and grain filling stage and fertilizer levels as 144 kg ha -1 is the best combination for having maximum output in terms of yield of the cultivar Bakhar-2000.
CERES-WHEAT模型是评价小麦作物生长发育和辐射利用效率的重要技术。在全球不断变化的气候条件下,需要一种合适的方法来提高大田作物的生长和繁殖技能。为此目的,在Sargodha收养研究农场进行了实地试验。试验包括4个施肥水平,即对照(推荐剂量)、84、114、144 kg ha -1和3个灌溉水平,即冠根+拔节+挤奶、冠根+孕穗期+灌浆、拔节+孕穗期+灌浆。主小区保持灌溉水平,次小区随机施肥。结果表明,增加施肥水平和灌溉频率可显著提高作物生长率(CGR)、叶面积指数(LAI)、叶面积持续时间(LAD)和净同化率(NAR)。拔节期、孕穗期、灌浆期氮肥用量为144 kg ha -1时,籽粒产量最高可达5528 kg ha -1。施肥量的增加增加了产量和产量成分,提高了植株的生长和辐射利用效率。综上所述,拔节+孕穗期和灌浆期3次灌溉和144 kg ha -1施肥量是巴哈尔-2000产量最高的最佳组合。

During storage, stored commodities are attacked by different kinds of insect pests. Among these storage insect pests, Rhyzopertha dominica Fab. is one of the most threatening pest. The present study was carried out at Grain Research, Training and Storage Management cell of the Department of Entomology, University of Agriculture, Faisalabad. Acetone extracts of Nicotiana tabacum and Piper nigrum at a concentration of 10, 15 and 20% and new chemistry insecticides Spinosad at concentrations of 1, 1.5 and 2ppm were evaluated alone and in combination for their mortality effect against R. dominica . The results revealed that spinosad showed more mortality than other two plant extracts of P. nigrum and N. tabacum . Spinosad showed maximum mortality 44.44% at the exposure time of 72hrs and minimum mortality of 4.83% at 24hrs exposure period. While in case P. nigrum showed the less mortality than spinosad and the N. tabacum . The application of P. nigrum was resulted into 1.67 and 5.42% mortality after exposure period of 24 and 72 hrs, respectively. The application of N. tabacum has been resulted into 23.75 and 2.34%mortality after 72 and 24hrs of treatment. It was also obvious from the results that a direct concentration and mortality response was observed in all the treatment applications. The results regarding the combine effect of plant extract and spinosad showed that the maximum mortality 57.73% was by the combinations of all three treatments of new chemistry insecticide and plant extracts. While mortality was minimum 28.73% where plant extract was applied only. From these results it was concluded that new chemistry insecticides had high toxicant action as compared to plant extracts against R. dominica and could be recommended for the management of stored grain pest R. dominica .
在储存过程中,储存的商品受到各种害虫的侵袭。在这些贮藏害虫中,沙纹虫(Rhyzopertha dominica Fab。是最具威胁性的害虫之一。本研究是在费萨拉巴德农业大学昆虫学系谷物研究、培训和储存管理小组进行的。研究了烟草和胡椒丙酮提取物浓度分别为10、15%和20%,新型化学杀虫剂Spinosad浓度分别为1、1.5和2ppm,分别单独和联合使用对白蝇的杀伤效果。结果表明,棘糖的致死率高于其他两种植物提取物。暴露时间72h时最高死亡率为44.44%,暴露时间24h时最低死亡率为4.83%。而黑穗病致死率低于棘叶虫和烟草粉虱。暴露24 h和72 h后,黑螺旋藻的死亡率分别为1.67%和5.42%。施用后72 h和24h的死亡率分别为23.75%和2.34%。从结果也可以明显看出,在所有的治疗应用中都观察到直接的浓度和死亡率反应。植物提取物与木皂苷联合施用的结果表明,新化学杀虫剂与植物提取物联合施用的死亡率最高,达57.73%。而仅施用植物提取物时,死亡率最低为28.73%。结果表明,与植物提取物相比,新型化学杀虫剂对褐飞虱具有较高的毒理作用,可推荐用于储粮害虫褐飞虱的防治。

Indoor concentrations of pollutants depend on the quantity of emissions, the volume of the polluted space and the rate of exchange between indoor and outdoor air. The principal indoor pollutants vary in rural and urban areas but they are a source of disease everywhere. Women are particularly at risk for a variety of adverse health effects related to indoor air pollution. Middle ear infection, tuberculosis, perinatal mortality (still births and death in the first week of life), low birth weight, eye irritation, cataract, asthma and oral cancer have all been associated with indoor smoke. For this purpose a study was conducted in rural areas of District Faisalabad which aims to assess the awareness/ knowledge about the health impacts of indoor air pollution on rural women. The sampling was consisted on four stages. At the first stage two tehsils were selected randomly from the Faisalabad District. At the second stage two union councils were taken from each tehsil through simple random sample technique. At the third stage two villages, from each union council were selected randomly and at the fourth stage 30 women from each village were taken purposively. The total sample size of women was 240. It was found that that the awareness of people about the adverse implications of the emission of bio-mass on their health particularly women and children who are more exposed to kitchen environment in terms closed and opened kitchen and its location, duration spent for cooking, types of fuel and stove is recommended.
室内污染物的浓度取决于排放量、被污染空间的体积以及室内外空气的交换速率。主要的室内污染物在农村和城市地区有所不同,但它们是无处不在的疾病来源。妇女特别容易受到与室内空气污染有关的各种不利健康影响。中耳感染、肺结核、围产期死亡率(死产和出生后第一周死亡)、出生体重过低、眼睛刺激、白内障、哮喘和口腔癌都与室内吸烟有关。为此目的,在费萨拉巴德区农村地区进行了一项研究,旨在评估对室内空气污染对农村妇女健康影响的认识/知识。抽样分为四个阶段。在第一阶段,从费萨拉巴德区随机选择了两个村庄。在第二阶段,通过简单的随机抽样技术,从每个地区抽取两个工会委员会。在第三阶段,从每个联盟理事会随机抽取两个村庄,在第四阶段,有目的地从每个村庄抽取30名妇女。女性的总样本量为240人。研究发现,建议人们认识到生物物质排放对其健康的不利影响,特别是妇女和儿童,他们更容易接触厨房环境,包括封闭式和开放式厨房及其位置、烹饪所用的时间、燃料和炉子的类型。

Current research is conducted to test the efficacy of essential oils extracted from some common plants that are mainly used in kitchen as a larvicidal and pupicidal agent against Culex mosquitoes. Oil extraction was done from parts (leaves, branches and rhizome) with Soxhlet’s apparatus using petroleum ether as a solvent. The knockdown effect was checked after 12, 24, 36 and 48 hours with different concentrations (50, 100, 150 and 200 ppm) along with a control treatment. The data was analysed by Probit analysis to calculate LC 50 & LT 50 . The results showed that the early larval instars (1 st & 2 nd ) were more susceptible than later ones (pupae). Ginger oil was more potent after 12 and 24 h against all life stages (2 nd , 3 rd , 4 th instar larvae & pupae ) due to lowest LC 50 values (171 & 136 ppm, 183 & 174 ppm, 246 & 199 ppm and 273 & 217 ppm for 2 nd , 3 rd , 4 th instar larvae & pupae respectively) followed by peppermint, basil, garlic and neem. However, basil oil released its components after 24 and 48 h and became effective more than others. So, we can use these oils in combination for the better management of mosquitoes.
从厨房常用的几种常见植物中提取精油作为杀幼虫剂和杀蛹剂,对库蚊的杀灭效果进行了试验研究。以石油醚为溶剂,用索氏装置从部分(叶、枝和根茎)中提取油脂。在不同浓度(50、100、150和200 ppm)以及对照处理下,在12、24、36和48小时后检查敲除效果。采用Probit分析法对数据进行分析,计算lc50和l50。结果表明,早期幼虫(1和2龄)比后期幼虫(蛹)更容易感染。姜油在12和24 h后对2、3、4龄幼虫和蛹的lc50值最低(分别为171和136 ppm、183和174 ppm、246和199 ppm和273和217 ppm),其次是薄荷、罗勒、大蒜和楝树油。然而,罗勒油在24和48小时后释放其成分,比其他油更有效。因此,我们可以将这些油混合使用,以更好地控制蚊子。

*Date fruits are traditionally used to prepare a wide range of products such as vinegar wine, jam and syrup named locally “Tahlawt” moreover, their direct consumption. The aim of this study is to investigate the antioxidant and anti-hemolytic activities of six syrups prepared traditionally form six different date fruit cultivars grown in southeast Morocco. Significant difference(P < 0.05) was established among analysed syrups. The highest phenolic (6.70 g GAE /100g DW) and flavonoid content (932.82 mg RE /100g DW) were found in Jihl syrups which possessed the highest antioxidant activity based on FRAP (9.55 mmol TE/100g DW), ABTS (8.27 mmol TE /100 g DW), DPPHIC50(381.99 µg/mL) and exhibited the highest membrane protective effect (317.70 min). Tamaajount syrup contains the lowest phenolic (3.72g GAE /100g DW) and flavonoid content (528.19 mg RE /100g DW) and presented the lowest antioxidant activity based on FRAP (5.30 mmol TE/100g DW), ABTS (4.68 mmol TE /100 g DW) and DPPHIC50 (1.095 mg/mL) as well as the lowest membrane protective effect (226.44 min).The results obtained suggest that date fruit syrups could be considered as a functional food or functional food ingredient because of their high phenolic compounds, which act as antioxidants and membrane stabilizer.

Vegetables are highly nutritious and value able part of our diet and the market sale of ready-to-use fresh vegetables grown rapidly as a result of consumer attitude. Many health benefits also related so its consumer and economic value increasing day by day. Fresh-cut or minimally processed vegetable means to washed, peeled, trimmed or sliced the vegetable into required size, chemically treated, packed into packaging material and finally stored in refrigerating temperature. Minimally process vegetables may also be considered as healthy vegetable with availability of their maximum saved nutrients. In present project spinach is selected to minimally process due to its rich nutritional contents and higher use in our daily life for the production of variety of products. Moreover nutrients like iron, calcium and vitamin K are present in higher concentrations due to which it become more beneficial against some serious health problems like of anemia, hemorrhage, clotting dysfunction and to maintain electrolytes balance in our body.
蔬菜营养丰富,是我们日常饮食中有价值的一部分,而即食新鲜蔬菜的市场销售由于消费者的态度而迅速增长。许多与健康有关的好处也使其消费和经济价值日益增加。鲜切或最低限度加工蔬菜是指将蔬菜洗净、去皮、修剪或切成所需尺寸,经化学处理,装入包装材料,最后置于冷藏温度下储存。最低限度加工的蔬菜也可以被认为是健康的蔬菜,因为它们可以最大限度地保存营养。在本项目中,由于菠菜的营养成分丰富,并且在我们的日常生活中用于生产各种产品,因此选择了最少的加工。此外,铁、钙和维生素K等营养物质的浓度较高,因此对预防一些严重的健康问题,如贫血、出血、凝血功能障碍和维持体内电解质平衡更有益。

Rape (Brassica napus) is an important and widely grown vegetable crop for food and income generation in most homesteads around Zimbabwe. Most households in Zimbabwe use inorganic fertilizers to improve production of rape in sandy soils which in turn are robbing the soil of its fertility. The present study investigates the effects of vermicompost as a soil supplement on growth and yield of rape compared to chemical fertilizers. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. A set of different vermicompost treatments (2.1%, 4.2%, 8.0%, 12.5%, and 12.5%) and inorganic fertilizer treatments (0.25%, 0.33% and 0.4%) were compared. Results revealed that the inorganic fertilizer treatments favored the growth and yield of rape more than vermicompost treatments. The inorganic fertilizers had quicker rate of release of nutrients as well as higher level of plant available nutrients. Likewise, the number of leaves, leaf length, number of marketable leaves, fresh yield mass, leaf width and whole length was also significantly better in case of inorganic fertilizer treatments. Generally, all treatments varied (p<0.05) as the growth progressed. There was significant interaction (p<0.05) between the treatments at 10 day intervals which was expressed in cumulative number of leaves and number of marketable leaves. It was concluded that use of vermicompost alone as a soil supplement in sandy soil for production of rape lead to lower growth and consequently yield responses. Hence the sole use of vermicompost as soil supplement should be discouraged and an integrated nutrient management plan may be evaluated as the most logical solution.
在津巴布韦周围的大多数家庭中,油菜是一种重要的、广泛种植的蔬菜作物,用于粮食和创收。津巴布韦的大多数家庭使用无机肥料来提高沙质土壤中油菜的产量,这反过来又剥夺了土壤的肥力。研究了蚯蚓堆肥与化肥相比对油菜生长和产量的影响。实验采用随机完全区组设计(RCBD), 3个重复。采用不同蚯蚓堆肥处理(2.1%、4.2%、8.0%、12.5%和12.5%)和无机肥处理(0.25%、0.33%和0.4%)进行比较。结果表明,无机肥处理比蚯蚓堆肥处理更有利于油菜的生长和产量。无机肥料的养分释放速度较快,植物速效养分水平较高。无机肥处理的叶片数、叶长、可售叶数、鲜产量质量、叶宽和全长也显著优于无机肥处理。总的来说,随着生长的进展,所有处理都有差异(p<0.05)。每隔10 d,处理间的互作显著(p<0.05),表现在累积叶片数和可售叶片数上。结果表明,在砂质土壤中单独施用蚯蚓堆肥对油菜的生长和产量影响较小。因此,不应单独使用蚯蚓堆肥作为土壤补充,而应评估综合营养管理计划是最合理的解决方案。
