يعد علم فيزيولوجيا الحشرات أو علم وظائف الأعضاء من العلوم الضرورية للعاملين والقائمين على دراسات كل ما يخص الحشرات، فهو يهتم بدراسة التركيب الدقيق لأنسجة الحشرة من جهة ولفهم ميكانيكية العمل الفيزيولوجي لأعضائها المختلفة من جهة أخرى، وهذا ما يساعد في إيجاد السبل المثلى لمكافحة الآفات الخطرة على منتجاتنا الزراعية، وهذا ما عبر عنه العالم ويغلوورث إذ قال: تعد فيزيولوجيا الحشرات لبعضهم كالوصف لعلم الحشرات الإقتصادية... ويعتمد غالباً التطبيق العملي لطرق المكافحة التي تكون المبيدات الحشرية أو التدخل في بيئة الحشرات على معرفة فيزيولوجيا الحشرات المراد مكافحتها، إذ يخدم علم الفيزيولوجيا في تفسير الإجراءات المعتمدة في المكافحة.
لقد توخينا في هذا الكتاب العملي لفيزيولوجيا الحشرات من خلال التعرف عملياً على الأعضاء الداخلية للحشرات ودراسة بعض المكونات الخلوية والهرمونات الجنسية، أن يتميز بالحداثة بالإعتماد على آخر معطيات المجهر الضوئي والمجهر الإلكتروني الماسح وتقنيات البيولوجيا الجزيئية والكروماتوغرافيا، وان يتميز بالبساطة والوضوح وحسبنا أن يكون هذا المجهود المتواضع عوناً للطلاب وللعاملين في مجال الحشرات ومكافحتها.
