يعتبر مرض الكوكسيديا من اهم الأمراض في الدواجن والتي تسبب خسائر فادحة للمربيين لان هذا المرض يسبب نقص شديد في وزن الطائر ويعطل نموه ويقلل معدل التحويل الغذائي ويسبب نسبة نفوق عالية ومن اهم أعراضه الظاهرة هي الاسهال المدمم(الاسهال الاحمر)
This document discusses stick insects (order Phasmida), including that there are approximately 2500 species. It describes the life cycle of stick insects, from egg to nymph to adult. Stick insects exhibit behaviors like catalepsy, photohorortaxis, and thanatosis. They are mostly found in tropical and subtropical regions, with the greatest diversity in Southeast Asia, South America, Australia and the United States. Control methods for stick insects include biological controls like parasitic wasps, and removing insects by hand, though pesticides have not been researched for efficacy against stick insects.
Stick insects are arthropods of the order Phasmida that resemble sticks or leaves. They are 7 to 10 centimeters long, wingless, and range in color from brown to green. Females lay hundreds of eggs without needing fertilization by males. Stick insects use their segmented legs and antennae to move nocturnally while remaining motionless during the day among vegetation where they feed herbivorously on plants like roses in warm regions.

جشن باشکوه نوروز بی تردید یکی ازجشنهای زیبای ایران بزرگ و دنیا می باشد.
نوروز و شهرت جهانی آن که موجب شده سازمان ملل روز بیستم مارس را به
آن اختصاص دهد، نشانه ای از ذوق و سلیقه و تفکر منطقی کیانیان بوده است.
This document discusses the up country live wood termite (Postelectrotermes militaris), a pest of tea plants in Sri Lanka. It describes the termite's life cycle of eggs, nymphs that develop into workers or supplementary reproductives, and winged adults. The termite colonies of 3000-5000 individuals reside in single tea bushes and damage plants by constructing galleries in the roots, collar, and branches, eventually causing wilting and breakage. Control involves removing and burning infested plants and roots.
This document provides an overview of three orders of neopteran insects: Dermaptera, Phasmida, and Isoptera. It discusses the key characteristics and classifications of earwigs, leaf-like and stick-like insects in the orders Dermaptera and Phasmida. It focuses on termites in the order Isoptera, describing their true social structure with different castes like workers, soldiers, primary and secondary reproductives. The document aims to teach students about these insect groups, with a focus on the economically and ecologically important termites and their social life.
The document discusses the muscular system in insects. It notes that all insect muscles are striated like vertebrate cardiac and skeletal muscles. The main types of muscles are skeletal muscles which power movement and include flight, leg, head, and abdominal muscles. Visceral muscles power internal organs. The only muscle type in insects is striated muscle as they do not have smooth or cardiac muscle. Muscle structure and physiology are also described.
This document provides an overview of the muscular system, including the structure and function of muscles. It discusses the three main types of muscles - skeletal, smooth, and cardiac - and their characteristics. Skeletal muscles, also called voluntary muscles, are under conscious control and allow for movement. The major skeletal muscles and their actions are identified. The document also examines how muscles contract through isotonic, eccentric, and isometric contractions, and how muscle fibers and their fast-twitch and slow-twitch types relate to muscle performance and endurance.
تربية الفري
ينتمي طائرالفري أو السُّمْان (السُّمَّاني)، مثل البط والإوز، إلى مجموعة الطيور المهاجرة. إسمه القديم السَلْوَى كما ورد في الكتب المقدسة. ومن أسماءه أيضاً قتيل الرعد، إذ يُقال أنه إذا سمع الرعد مات. والفري من أكثر الطيور البرية التي تُصطاد في العالم، ويربى لعدة أهداف، إما لإنتاج اللحم والبيض أو كهواية لجمال الريش المتعدد الاشكال والألوان في بعض الأنواع، أولسماع أصواته و تغريداته الموسيقية، كما أنه يستخدم كحيوان تجارب في البحوث الطبية. ويقال أن لبيضه خصائص غذائية وصحية متميزة عن بيوض باقي الطيور الداجنة الأخرى، بعضها شبه مثبت علمياً، وأكثرها ينتمي إلى الطب الشعبي وطب الوهم.

The Food and Agriculture Organization of the United Nations (UNFAO) operates a global early warning system that monitors the situation and provides alerts and warnings in order to reduce the frequency, duration and intensity of devastating plagues that can quickly wipe out a farmer's livelihood and threaten food security on a national and continental scale.
