“…In 2019-2020 Pakistan face sever desert locust plague across three provinces. The species were later identified as S. gregaria gregaria travelled all the way from Africa to Asia via Middle East (Sultana et al, 2021Ahmad et al, 2020. This species goes under incomplete metamorphosis.…”

“…Biocontrol and Bio pesticides require time, optimum temperature and humidity for controlling the desert locust and cannot be applied in emergency situations. Pesticides such as Lambda-Cyhalothrin 2.5 EC, Chlorpyrifos 40 EC, and Deltamethrin 2.5 EC can be sued in emergency situation to obtained immediate results to tackle the situation effectively (Ahmad et al, 2020).…”

Desert locust has negative impact on world vegetation, severely affected Africa and Asia in 2020-21. The pest persists in both gregarious and solitary forms. In Pakistan, the majority of the nation experienced a desert locust attack in 2020. Seven to ten districts in Khyber Pakhtunkhwa were seriously impacted. The study was carried out to test the efficacy of different concentrations of Lambda-cyhalothrin 2.5 EC against adult and hoppers/nymph in field and laboratory conditions. The applied concentration was 4%,3%, 2%, 1% and 0.5 % for adults in field and lab conditions, while 2%, 1.5%, 1%, 0.5% and 0.25% for nymph’s trials. Under field condition against adults all the applied concentrations were at par with each other except 0.5%, which showed significantly lower mortality rate (60%). A similar trend of toxicity was also recorded for the laboratory trials. More than 85% mortality was recorded in all treatment except 0.5%, which was 65%. Against hopper all concentration showed significant higher mortality (above 80%) except the nymphs sprayed with 0.25% concentration under field conditions. Similar results were also obtained for vitro trials against nymphal stage. It is concluded an average concentration (3%) should be applied for adult to avoid resistance and pest escape. For hoppers/nymph the recommended concentration should be 1%. Further studies should be carried out regarding the resistance to different types of insecticides under field and laboratory conditions.

The goal of this work is to use novel mixed additives of Nano Chitosan combined with nanoparticles and other substances that could inhibit the microbial growth of the wooden coffin. The wooden coffin, covered with a layer of black resin and coloured materials, was found in bad condition, and covered with a thick layer of dust. Several ties were used to preserve the sides of the coffin in the previous restoration. Cellulose agar was used to cultivate fungi, and nutrient agar was used to cultivate bacteria. The fungi were Aspergillus flavus, Cladosporium herbarum, and Aspergillus niger, while the bacteria were G+ve Bacillus sp., Bacillus megatrium, and Bacillus jeotgali. composite of ZnO NP, Ag NP, p-chloro-m-crysol (PCMC), Shim plant (Sh) with Nano Chitosan with 1, 2, and 3% concentrations were chosen for the purpose of treating microbial infections and determining which materials would work best to prevent microbial growth. Nano-chitosan + Ag NP and ZnO NP (1%) gave the best inhibition for Aspergillus niger (30mm). Nano-chitosan + PCMC (1%) gave the best inhibition for Aspergillus flavus (25mm), Cladosporium herbarum (25mm), and Bacillus jeotgali (40mm). The same effect was found for Nano-chitosan + PCMC (1%) and Nano-chitosan for Bacillus megatrium and G+ve Bacillus sp. (40mm).
