Pest Control: The Egyptian Cotton Leaf Worm

Introduction Egyptian cotton worm Spodoptera littoralis Bosid (Lepidoptera: Yaga) is a multifeeding insect insect that is considered one of the most serious insect pests of a wide variety of Egyptian crops (Magd El-Din and El). -Gengaihi, 2000). It is an important cotton pest in Africa, the Middle East and Southern Europe (Hosny et al., 1986). Therefore, one larva can destroy 66 cm 2 cotton leaves (Scarpellini, 2001). In addition, it is widely distributed in the Mediterranean, Africa, Asia and Europe (El-AW, 2006).

Cotton is a crop that requires a lot of water, and it is often contaminated with severe chemical substances that not only harm the environment but also harm the health of farmers. Due to the length of the fibers themselves, the world's best Egyptian cotton has long been an exception. After that, in 1977, Dr. Ibrahim Abbey established SEKEM. This name is derived from the "vitality" of the ancient Egyptian hieroglyphs and is a new biodynamic method that helps organic crop cultivation, school establishment, community support, and eventually Egypt's agricultural reform reform It was injected into the Egyptian desert by use.

In 1990 the Egyptian government asked Sekem to find a biodynamic method to grow cotton to reduce the use of pesticides. Not only did Sekem develop this concept based on the use of pheromones to combat cotton insects, the results were convincing and Egyptian authorities officially recommended this method. This method was promoted through the organization used in Egypt's Egyptian Biodynamics Association (EBDA) in nearly 80% of the cotton field, reducing pesticide usage by 90%, averaging 30,000 tons of chemistry per year I saved materials. . The average yield of raw cotton increased by about 30% to 1,220 kg per acre, and some fiber quality parameters are better than those of traditional agriculture. (Extract from excerpt from this book)

Bt gene is introduced. Crops do not replace these harmful systems. They are a continuation of an unsustainable pest control strategy to create new pests and super pests, not to control pests. Monsanto claims that Bt cotton obviously is a wrong advertisement, without requiring pesticide spray. The main reason for Bt trait genetic engineering is that Bt reduces the use of pesticides. A booklet from Monsanto shows pictures of several worms - "You will see them on cotton, it is in the UK, do not spray." Today Monsanto's defenders also have Bt Has reduced the use of agricultural chemicals. The destruction of Punjab shows that this is not true
