Ayesha Ilyas1, Hafiz Azhar Ali Khan2,* and Abdul Qadir1,* up to investigate the settling and ovipositional deterrent effects of crude leaf extracts of six indigenous plants viz., amaltas (Cassia fistula), datura (Datura alba), neem (Azadirachta indica), niazboo (Ocimum basilicum), yellow kaner (Thevetia peruviana) and safeda (Eucalyptus camaldulensis) against the peach fruit fly, Bactrocera zonata (Saunders), at 2% concentration in a free choice bioassays. Ac...

MUNICIPAL WASTEWATER TREATMENT BY COAGULATION/ FLOCCULATION PROCESSES VIA OPTIMIZATION OF INOCULATION DOSE AND SETTLING TIME ratio of 2:0.5 mL for settling time of 13 minutes. As treatment results, not only removed suspended
solids (86%) but a tremendous decrease was observed in color, chemical oxygen demand (COD) and turbidity by
96%, 66% and 89%, respectively.

...:13 ml respectively. The settling time was 25, 35 and
20 minutes respectively for lime, alum and alum+lime. The results revealed that the combine treatment (Alum +
Lime) effectively removed suspended load up to 90%, along with 82% BOD, and 80% COD respectively. Therefore,
it was concluded that the installed small scale treatment plant is not enough in its present form and needs to be
upgraded by adding a coagulat...

...lime and alum + lime the settling time interval was 40, 35 and 20 minutes respectively. Results revealed that the combine treatment (Alum + Lime) effectively reclaimed Total Suspended Solid (TSS) up to 85%, along with 80% BOD, and 75% COD. Waste management is core issue that affects the health of people residing in surroundings of Nullah Lai stream. During the question survey it was observed that 70% respondent reported that they are facing spread of diseases ...

...e different puddled soil settling periods (24, 48 and 72 hours) and seedling age (20, 25 and 30 days) for decreasing the missing hills while improving plant and root growth, and consequently grain yield of MTR. Experiment was conducted using randomized complete block design (RCBD) with split-plot arrangement and three replications during 2020 and 2021. Shoot and root length as well as dry mass of rice seedlings sown in trays were significantly increased with i...

..., flies settled and post settling reproduction. There was inverse response of peach fruit flies to increasing concentration of plant extracts. Minimum significant number of fruit flies (0.58) settled after 18 h, reaching to its peak (1.73) after 42 h showing a decreasing trend subsequently. Hence, all the plants exhibited insecticidal potential and resulted in reduction of fruit fly population in laboratory condition. Thus, these plant extracts could be consid...
