رشته حشره‌شناسی :

حشره شناسی علمی گسترده است که از جنبه‌های مختلف به مطالعه حشرات می‌پردازد

خصوصیات ظاهری

از جمله خصوصیات شکل ظاهری تشریح، ویژگی‌های زیست محیطی، اصول مبارزه و سیستماتیک (طبقه بندی) می‌باشد.

شاخه‌های علم حشره‌شناسی

با توجه به مشکلاتی که حشرات آفت ایجاد مینمایند، علم حشره‌شناسی دارای شاخه‌های مختلفی مانند: حشره‌شناسی پزشکی، حشره‌شناسی کشاورزی و حشره‌شناسی دامپزشکی تقسیم می‌شود.

حشره‌شناسی پزشکی

در حشره‌شناسی پزشکی به بررسی حشراتی پرداخته می‌شود که اغلب خونخوارند و در ضمن خونخواری انسان ایجاد خارش یا سوزش، تورّم، قرمزی و حساسیّت پوستی می‌شود. در ضمن تعدادی از آنها ناقل بیماری‌های متعددی مانند ملاریا، تب زرد، تب دام، طاعون، تیفوس و سالک می‌شود. از طرفی برخی از حشرات نیز سمّی هستند و نیش آنها باعث اذیّت و مسمومیّت افراد می‌گردد.

I know this if off topic but I'm looking into starting my own blog and was wondering what all is
needed to get setup? I'm assuming having a blog like yours would
cost a pretty penny? I'm not very web smart so I'm not 100%
certain. Any recommendations or advice would be
greatly appreciated. Cheers

My coder is trying to persuade me to move to .net from PHP.
I have always disliked the idea because of the expenses.
But he's tryiong none the less. I've been using WordPress on several
websites for about a year and am nervous about switching to another platform.

I have heard excellent things about blogengine.net.
Is there a way I can import all my wordpress content into it?
Any help would be greatly appreciated!
