Four promising natural plant s previously proved to prolong the activity of Spodoptera littoralis (Boisd.) nuclepolyhedrovirus ( Spli NPV) suspension under Egyptian field conditions , examined alone or in combination with virus in six mixtures. Screening results were based on bioassay. Different parameters were investigated to prove the value of protection, % of mortality, reduction %, LIT 50 , Potency and Original Activity Remaining (OAR) .DPPH assay was inv estigated

Cauliflower is the most popular vegetable in the whole world.it is a great green vegetable which is very good for our health.it is a term of cultivated plant.it also belong with the brassica family. Firstly cauliflower is a Latin word. Which meaning a great flower because, in the beginning it is belong Italy because Italy produce a large number of cauliflower production on that time.it is very familiar with the cabbage because it also belong to the brassica family. Therefore, both have a lot of similarities

Beet armyworm (Spodoptera exigua) Mature beet armyworm larva feed on the chili leaves. The organic method to control the beet armyworm is by providing biological control as their natural enemy that can parasitize the larvae. The application of Bacillus thuringiensis can also help to control them. Flea beetles Flea beetles damaged young plants and seedlings that may reduce plant growth or even killed. The application of a thick layer of mulch may help prevent flea beetles to reach the plant. The organic

Although the production of insecticidal baculoviruses in insect cell cultures has been proposed as an alternative to overcome the limitations of the in vivo processes, so far no in vitro process could be even implemented on an industrial scale in India, and baculovirus occlusion bodies are still produced in infected insect larvae. Some factors that 25 years ago have hindered the development of large-scale production processes for baculoviruses in insect cell cultures, such as the sensitivity of insect

The study of JA biosynthesis in both dicots and monocots revealed that phospholipids such as linolenic (18:2) and α-linolenic (18:3) acid are released from chloroplast membranes through the action of phospholipases. In the subsequent steps formation of hydroperoxy octadecadienoic acids (e.g., 13S-HPODE and 9S-HPODE) occurs through dioxygenation. These steps are catalyzed by lipoxygenases (LOXs; 9-LOX and 13-LOX). In futher steps HPODEs are converted to 12-oxo-phytodienoic acid (12-OPDA) in plastids

food security. Distribution of insect- pest will also be influenced by the change in cropping pattern triggered by climate change. Major insect pests such as cereal stem borers (chillo, sesamia and scirpophaga), pod borer (Helicoverpa, Marucaand Spodoptera), aphid and white fly, may more to temperate regions, leading to greater damage in cereals, legumes, vegetables and fruits crops. Host plant resistance, biopesticides, natural enemies and synthetic chemicals are some of the potential options for

Program: Master’s in Microbial Biotechnology Statement of Purpose Having pursued relevant projects, courses and considering my aptitude, I find myself interested in life sciences and more specifically in Microbiology. I believe that pursuing Masters in Microbial Biotechnology at North Carolina State University will help me to widen my knowledge, hone my technical and managerial skills and provides me an opportunity to contribute

Abstract: Abstract for general audience: Introduction: The first research article explaining the use of baculoviruses as expression vectors in insect cells was published in the early eighties (Smith et al., 1983). Baculovirus-based expression systems have been used for more than twenty years. During the last two decades, the baculovirus expression system has improved tremendously, from its humble origin in the early 1960s. However, the robust system for the expression of proteins is yet to
