The study essay on Insect Entomopathogenic Nematode

hello
can you help me to correct my grammatic mistak ?

The first Study of Insect Entomopathogenic Nematode In North
The most important biocontrol agents are considered entomopathogenic nematode. Due to growing application of this pathogen in recent decades, the identification of these factors is very important. The study in 2011 from three different habitats were sampled of South Island.

In continuing efforts to morphological characteristics, molecular and crossbreeding tests of native species collected are used for identification. With galleria trap method, of 60 soil samples collected, five samples of the two Steinernemaand Heterorhabditisgenera was isolated. Determining classic specification according to apparent characteristics and morphometricthe grouping so called isolates Boj1, Boj7, Boj8 and Boj9 group "feltiae" and HBoj isolates was in group "bacteriophora". The phylogenetic analysis on sequence data, gene regions ITS and 28S, showed that isolates attributed to Boj1, Boj7, Boj8 and Boj9 belonging to the "feltiae" group "Steinernema" genera and also the HBoj isolates was belonging to "bacteriophora" group of "Heterorhabditis" genera. ). Reconstruction of phylogenetic trees using both ITS and D2/D3 genes showed that four isolates, Boj1, Boj7, Boj8 and Boj9 were grouped in a clade with other species of "feltiae"group (of Steinernema)These results were also verified in reconstructed phylogenetic tree for "bacteriophora" group species and HBoj isolate based on ITS gene.

Cross breeding tests result between species and Boj1, Boj7, Boj8 and Boj9 isolates with S.feltiaereference isolates, it was confirmed that the first isolates (Boj1) belongs to the S.feltiaespecies.

The other three isolates (Boj7, Boj8 and Boj9), was awarded the "Steinernema" genus Online survey, the first study of entomopathogenic nematode native population in North Khorasan.

The most important biocontrol agents are considered entomopathogenic nematode.------------- I would suggest;

Entomopathogenic nematodes are considered to be the most important agent for biological control of insects.

five samples of the two Steinernemaand Heterorhabditisgenera waswere isolated.

thank you dear Dumi for correction
just can i know if i use are considering is it false?

Dear Sanaz,

I guess what you are asking is that whether what you have written is incorrect. It has a small grammatical error as follows;
The most important biocontrol agents are considered to be entomopathogenic nematodes .

The problem with your writing, apart from grammar for which you need to pay lots of attention, is that most of your sentences do not flow properly and sounds very abrupt. Unless you have some subject knowledge, which I do not possess, it is very difficult to catch the idea. That is where I struggle in helping you :D.

However, you can avoid this problem by shortening your sentences and limiting one sentence to one idea. That would help you improve clarity of your writing

A few more;

In continuing efforts to identify morphological characteristics, molecular and crossbreeding tests were conducted with the use of native species collected are used for identification .

The other three isolates (Boj7, Boj8 and Boj9) (no comma here)waswere awarded the "Steinernema" genus Online survey, the first study of entomopathogenic nematode native population in North Khorasan.

Hi; I am not expert on this research area, but as a reader I have some suggestions. I hope these ideas be helpful.
Line one " Due to growing application of this pathogen in recent decades, the identification of these factors is very important" : The structure of the sentence is a little farsi, (You used the term "in the recent years", therefore you should use a sentence with the tens of present perfect). I think it would be better to be written in this way: " The identification of these factors has become very imperative/important issue due to the development of this pathogen's applications in the recent decades".

the word "identification" was used for several times, you can use the word "recognition" instead.
"..was in group "bacteriophora"...": Suggestion: (...were grouped/classified as "bacteriophora"...)
"Belonging" is a good word but as a suggestion the terms such as "categorized as", "classified as", "included in", "a part of" could be appropriate in this context.

"...isolates, Boj1, Boj7, Boj8 and Boj9 were grouped in a clade with other species of "feltiae"group..": In a scientific report the sentences should not be definite. It would be better to use "could" and "might". Thus in my view, the sentence should be change into" ...isolates, Boj1, Boj7, Boj8 and Boj9 could be grouped in a clade with other species of "feltiae"group.."

I could not understand this sentence "Cross breeding tests result between species and Boj1, Boj7, Boj8 and Boj9 isolates with S.feltiaereference isolates, it was confirmed that the first isolates (Boj1) belongs to the S.feltiaespecies.". It is too complicated for realizing. Would u please write it in farsi??

Guys please take a look on my essay entitled " a discussion about two views toward talent". Thanks

thank you dear dumi and a.zafari

yes sure
in persian:

thank you for your help

Hi again Sanaz, this sentence would be more understandable if you change it with the sentence below:
"The results of breeding tests among the isolates of Boj1، Boj7، Boj8 and Boj9 revealed that the first isolate (S.feltiae) and the reference isolate (Boj1) could belong to "S.feltiae" species and three other isolates (Boj7، Boj8 and Boj9) were classified as the species of "Steinernema".

حقیقتا متن سختی بود.
امیدوارم نوشته بالا کمک کننده باشه و به ماهیت علمی بحث لطمه نزده باشه
موفق و پیروز باشید

thank you very much
this was for thesis and i really thank you for reply to me
