Hello Seyed:

For a correct identification you must provide the type of host plant and the locality. In your photos you have damage caused by different orders of insects.

Figure 1 is caused by nymphs of grasshoppers (Orthoptera: Acrididae),  

figure 2 is caused by a larva of Lepidoptera.

Figure 3 are scale insects,

 Figure 4.is damage caused by leaf beetles in the family Chrysomelidae genus Epitrix sp. , probably E. similaris but need to know the host plant.

Figure 5 is damage by leaf beetles probably Cerotoma sp. in the family Chrysomelidae 

Figure 6 is a Miridae bug, this insect has sucking mouth parts.

Hello hussain

Insect Pests : Insect pests can be divided in to 3 main groups :

1. Chewing insects

2. Sucking insects

3. Boring, mining & soil insects

CHEWING INSECTS

Grasshoppers : Camouflage easily on plants due to their green or brownish colours. These insects cut irregular cuts and punctures on leaves. Tender shoots too are eaten. Their droppings are like tiny pieces of charcoal. As they hop from plant to plant, grasshoppers may be or may not be present on the damaged plant.

Brown tussock caterpillar : It is a larva of a moth which lays its white eggs in clusters, usually on the underside of leaves. The tiny, hairy caterpillars in a flock start scraping leaves. This makes the affected leaves look translucent. As they grow, they start nibbling the leaves, which get cut irregularly. Tender shoots, flower buds too are affected. Droppings of the caterpillars are globular.

Chafer beetle : This beetle too causes irregular cuts and puctures on leaves. This insect is active in rainy season. The chafer beetle is a nocturnal creature and causes the damage only at nighttime. During the day they hide in the soil.

Lemon Butterfly Caterpillar : This common and beautiful butterfly lays its solitary eggs on leaves of citrus plants. The tiny caterpillars, which hatch out of the eggs, resemble droppings of sparrows in colour and shape. Leaves and new growth is all chewed up. As the caterpillar grows bigger, it acquires green colour and then easily camouflages amongst the foliage.

Hello Marwa Alkharaz

Thank you so much

your sincerely

Dear Seyed,

You have too much questions. The answers you can find in a textbook of agricultural entomology. What do you mean under vermin insect? Regarding your photos, all are symptoms caused by chewing mouthparts. There is also a bug belonging to the family Miridae which has sucking mouthparts. The little insect in the first row and last picture cannot be appropriately seen. So I propose you to learn general and agricultural entomology at a good university because what you asked are part of the basic of a crop protection course. 

Hello Sir

Yes my field of study is artificial intelligence. So I do not know anything about agriculture at all. But I want to make an expert system for detecting insect kind and then prescribe the poison,  based on the insect's bite pattern type. So I asked this question.

I checked the book.it was useful to me.

Thank you Sir

Dear Seyed,

I think you should prepare this expert system together with some specialists of agricultural entomology.  

Yes.Exactly.

I have lack of skill in this subject.

Dear Seyed Muhammad Hussein Mousavi

It is very good projects , you may read about : role of  insect behavior in attraction to plant, the relation between insects-host plant, plant defense system, host plant selection, Chemosensory Bases of Host Plant Selection.the essential factors affecting insect behavior and plant defense system

Hello

it was perfect answer Mr.Constantino. Thank you so much.

In fact I was looking for your links Prof. Kawas. I will use them in my project.

Thank you for your consideration. It was completely motivational to me.

Best regards

you most welcome
