Five Area Councils were selected for the study from the six Area Councils of Federal Capital Territory (FCT-ABUJA) namely; Gwagwalada, Kuje, Kwali, Abaji and AMAC. Three markets were surveyed in each of the Area Council to obtain one measure of infested maize with maize weevils (Sitophilus species) and ten of the insects were selected randomly from each measure and kept separately in a covered jar containing ethanol solution. The sample were taken to Insect Laboratory (Insect Museum), at the Department of Crop Protection, Faculty of Agriculture, Ahmadu Bello University, Zaria, Kaduna State for identification. MI scope was used to carry out the morphometric measurement. The features of the insect measured include the wholebody length, Body width, Hind limb, Fore limb, Head, Antennae, Tarsi, Width of Femur, Femur. Then Microscope was use to view and compare the collected insects with other genus of Sitophilus in the insect collection boxes in the museum. The features measured were converted from pixel per length (p/l) to millimeter and subjected to Analysis of Variance (ANOVA) using statistical package version 9.0. The means were separated using Duncan Multiple Range Test (DMRT) at 5 % level of probability. Results obtained indicated that Kuje and Abaji Area Councils had varied diversity of features of Sitophilus granarius and only Sitophilus granarius was identified in all the five Area Councils of FCT-Abuja, Nigeria.

Leaf anatomical and micromorphological studies on Youngia japonica (Asteraceae family) were accomplished. In the North America, this wild plant is consumed as salad as a healthy diet. The whole plant is edible and has been consumed in past years especially during famine. The Chinese community has been using this plant to perform blood cleansing, to cure sore throat, diarrhoea, mastitis, shingles, sprains, and bruises. Since there is yet any comprehensive study on the taxonomic study of Y. japonica in Kuantan, this study aims to investigate and examine its leaf anatomical and micromorphological characteristics that can be used as a complete guidance for its identification and additional data for its species classification. The methods involved in the leaf anatomy included a cross sectioning method on the petiole, midrib, lamina, and margin using a sliding microtome, clearing of venation using basic fuchsin, and epidermal peel methods using Jeffrey solution. The micromorphology of the leaf was observed under a scanning electron microscopy (SEM). The result of the characteristics of leaf anatomical and micromorphological studies for Y. japonica found the type of vascular bundle at petiole which was an opened system, noncontinuous ring of separated vascular bundle arranged in arc-shaped with additional vascular bundles, there were presence of mucilage cells, incomplete marginal venation, anomocytic stomata at leaf epidermis, granules and crust of wax, and multicellular trichomes with different ended and capitate glandular trichome. In conclusion, the findings have shown that the anatomical and micromorphological characteristics have their taxonomic value and can be useful in the identification, differentiation, and classification of the plant at the species level.

The fresh arils of durian fruits contained approximately one-third of the fruit’s total weight; the remainder of the fruit, including the rinds and seeds, is considered waste. As a result, researchers investigated and studied the potential for these wastes to be processed into products or value-added products in various industries. This review aimed to discuss the potential for waste products of D. zibethinus to be converted into value-added products in a variety of areas. An extensive literature study was done on various search engines. Related previous research was selected for discovering the potential of D. zibethinus waste. This review found four fields of studies that gained interest in the invention of value-added products by using D. zibethinus waste, including activated carbon precursor, bio-composite product, bio-based polymer product, and bioethanol production. As Malaysia is growing in the food waste industry, more study needs to be done to successfully invent new value-added products from D. zibethinus waste such as rind and seed. The effort of this study could help in reducing unused D. zibethinus waste.

The herbal industry in Malaysia is facing problem of scarcity of the natural herbs due to excessive exploitation of natural forest. It is therefore necessary to cultivate these herbs and research is urgently needed on its agronomic aspects. A pot trial study was therefore carried with the following objectives: (i) to determine the effects of different organic fertilizer rates on height growth, and (ii) to measure selected foliar and soil nutrient concentrations. Treatments evaluated were: (i) 10% of guano manure mixed with 90% of soil (T1), (ii) 20% of guano manure mixed with 80% of soil (T2), (iii) 30% of guano manure mixed with 70% of soil (T3), (iv) 40% of guano manure mixed with 60% of soil (T4), (v) 50% of guano manure mixed with 50% of soil (T5), (vi) 60% of guano manure mixed with 40% of soil (T6), (vii) 70% of guano manure mixed with 30% of soil (T7), (viii) 80% of guano manure mixed with 20% of soil (T8), (ix) 90% of guano manure mixed with 10% of soil (T9), and (x) Soil without guano manure (control) (T10). The experiment was conducted using a Completely Randomize Design (CRD) with five replications. Plant height for each treatment was recorded on monthly basis for four months duration. Selected nutrient concentrations in the plant leaves after harvest and in the soil before planting and after harvest along with the soil pH were analysed. Soil total N was determined using Kjeldahl method while total P was determined using Aqua regia method. The exchangeable K, Ca, Mg, Zn, Cu, and Na were extracted using double acid method and their concentrations determined using atomic absorption spectrophotometry (AAS). Dry ashing method was used for the determination of P, K, Ca, Mg, Zn, Cu, and Na concentrations in plant leaves while total N concentrations was determined using Kjeldahl method. Guano manure showed significant effects on plant height, and concentrations of total N, total P, Ca, Mg and Zn in the leaves. The T3 recorded significantly higher plant height at 76.50 cm while the lowest was in T9 at 50.60 cm. The concentrations of K, Cu and Na on the other hand recorded no significant effects. Nutrient concentrations in the soil after harvest decreased compared to before planting while soil pH increased as level of manure increased in the soil before planting and after harvest. It is advisable to conduct field trial experiment for further study.

Empirical evidence of the presence of bioactive compounds in plants is indispensable, given that medicinal plants play a pivotal role in the quest for new antimicrobials. In this study, leaves of Citropsis articulata from three forest reserves (Mabira, Budongo, and Kibale) in Uganda were extracted with distilled water and methanol using infusion and maceration methods, respectively. The total phenolic (TP), total flavonoid (TF), total alkaloid (TA) and total saponin (TS) contents of the extracts were evaluated using UV-Vis spectrophotometric based methods before the fingerprint of each extract was established using high-performance liquid chromatography. In vitro antimicrobial activities of the extracts were examined against standard strains of common pathogenic microbes, including Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Candida albicans using agar well diffusion and microtitre plate-based assays. Results showed that the methanol extract had a significantly higher content of the secondary metabolites compared to the aqueous extract, with samples from Mabira showing the highest level of TP (68.92 mg GAE/g), samples from Budongo had the highest level of TF (11.28 mg QE/g) and TS (101.94 mg DE/g). In comparison, samples from Kibale showed the highest level of TA (66.29 mg AE/g). In the antimicrobial study, methanol extract showed significantly higher potency than the aqueous extract for all samples from the three locations. The plant extracts showed substantially high potency against Escherichia coli, with samples from Mabira exhibiting the maximum zone of inhibition (29.5±0.5 mm) at 50% w/v and lowest minimum inhibitory concentration (MIC) of 1.56% w/v. The extracts also demonstrated bactericidal (MBC) and fungicidal (MFC) potency against the test microorganisms in the order; Escherichia coli > Staphylococcus aureus > Pseudomonas aeruginosa > Candida albicans. This study demonstrated that Citropsis articulata leaves have potentially potent bioactive compounds that could be explored for future antimicrobial drug development.

Microalgae are unicellular photosynthetic microorganisms which are able to survive in extreme environmental conditions, specifically low temperature, high evaporation rates as well as low water availability. Polar microalgae from the Antarctic region have received attention from researchers due to their special adaptations for surviving in extremely cold environments and being isolated from various types of samples. Four Antarctic soil samples were used on this study namely-Sample A, Sample B, S18 and S30. All soil samples were subjected to serial dilution and spread on BBM followed by 3 weeks incubation at 25oC with periodic light. Only soil sample S30 showed positive microalgae growth after additional 3 weeks incubation period. Consequently, soil sample S30 was proceeded to isolation of microalgae using BBM, 3N- BBM+V, JM and MWC media. Observable growth of green microalgae could only be obtained using 3N-BBM+V and JM media. Moreover, 3N-BBM+V medium successfully produced the highest number of microalgae colonies recovered from Antarctic soil sample. Isolation of microalgae from Antarctic provides resources for various industrial and commercial applications.

Nata de coco is a complementary treat of beverages made from coconut milk or water which was fermented by Acetobacter Xylinum bacteria. Although most nata are generally made with coconut milk or water, nata de coco can be made using other ingredients such as coconut milk, molasses or molasses, and other juices such as melons, pineapples, oranges, bananas, guavas, strawberries etc. This study was undertaken to design, construct and develop a new Strawberry flavored Nata De Coco and Nata De Coco drink and its comparative quality assessment respect to comparative quality evaluation of Nata De Coco drink. Best quality Nata De Coco were obtained by using 71.34% water, 13% Sugar, 15% Nata De Coco, 0.03% Gellan Gum, 0.06% Sodium Citrate, 0.12% Calcium Lactate, 0.01% Ascorbic Acid, 0.03% Potassium Sorbate, 0.012% Sodium Benzoate, 0.12%,Strawberry Flavor, 0.23% Citric Acid Anhydrous, 0.05% Liquid Cap. Overall analysis shows that Nata De coco Drinks which are produced with 15% Nata De Coco shows the best results and for other parameters results are respectively 0.23%, 0.0144 acidity; 13 ± 0.2 °Brix and pH 3.6± 0.1. As per evaluation of three samples, average value of taste of sample S3 is accepted. Because we used less citric acid in S1, more less citric acid in S3. Taste of S3 is accepted because taste quality of S1 & S2 is not perfect as per standard. Flavor of sample S3 is better than S1 & S3.Organoleptic test of S3 is better than S1 & S2. At the end of all evaluation, S3 is accepted for manufacturing. Because it is tasted well among the samples are made.
Nata de coco是由木醋杆菌发酵的椰奶或水制成的饮料的补充处理。尽管大多数纳塔通常是用椰奶或水制成的，但椰子纳塔也可以用其他成分制成，如椰奶、糖蜜或糖蜜，以及其他果汁，如瓜、菠萝、橙子、香蕉、番石榴、草莓等，构建和开发了一种新的草莓口味的Nata De Coco和Nata De Coco饮料及其比较质量评价。通过使用71.34%的水、13%的糖、15%的Nata De Coco、0.03%的盖兰胶、0.06%的柠檬酸钠、0.12%的乳酸钙、0.01%的抗坏血酸、0.03%山梨酸钾、0.012%的苯甲酸钠、0.12%Strawberry Flavor、0.23%的无水柠檬酸、0.05%的Liquid Cap获得最佳质量的Nata De Coco。综合分析表明，用15%的纳塔可可生产的纳塔椰子饮料效果最好，其他参数的酸度分别为0.23%、0.0144；13±0.2°白利糖度和pH 3.6±0.1。根据对三个样品的评价，接受样品S3的味道的平均值。因为我们在S1中使用了较少的柠檬酸，在S3中使用了较多的较少柠檬酸。S3的味道被接受，因为S1和S2的味道质量不符合标准。样品S3的风味优于S1和S3。S3的感官测试优于S1和S2。在所有评估结束时，S3被接受用于制造。因为它在制作的样品中味道很好。

The bean flower thrips, Megalurothrips usitatus is a major pest of mung bean that causes flower dropping and significant yield loss of the crop. M. usitatus demonstrated to have variable lifespan when reared on different leguminous hosts but on mung bean, an important pulse crop in Bangladesh, is unknown. The experiment was conducted to determine the biological attributes of M. usitatus on mung bean in a climate control chamber at 26 ± 1°C, 75 ± 3% RH, and 16:8 hours L:D in the laboratory. The results revealed that the incubation period, first instar larva, second instar larva, prepupa, and pupal period of M. usitatus were 3.13 ± 0.06, 1.48 ± 0.05, 2.30 ± 0.08, 1.30 ± 0.07, and 2.26 ± 0.13 days, respectively. The combined developmental period from egg to adult was 10.54 ± 0.15 (mean ± SE) days. The larvae of M. usitatus were similar in appearance to the adults, but they lacked wings and were smaller and different in color. The first instar was pale yellow, while the second instar was darker and larger, ranging from deep yellow to orange-red. The wing pads of the prepupae were shorter than that of the pupae. The antennae of the prepupa were straight, but they were bent in the pupa. In the case of pre-adult mortality of M. usitatus, the mortality of the first instar larva was 14.41%, second instar larva 22.77%, prepupa 14.10%, and pupa 65.67%. The pre-adult mortality was 80.51% overall. Adult males had lower longevity (6.42 ± 0.44 days) than females (12.07± 1.56 days). The developmental period of M. usitatus on mung bean indicated the suitability of the leguminous crop as a potential host, as well as the need for information on the pest’s various growth stages in order to design effective management strategies.
