Filter your query by comparing the field related to the combobox text,
may be something like this,

rscombo.Open "select * from Pquery where item_name ='" & Combo1.Text & "'", con, adOpenDynamic, adLockOptimistic

Private Sub Combo1_Click()

    Set rscombo = New Recordset

    Select Case Combo1.Text

If rscombo.BOF = False Then

This statement is to check if any record bearing that item_name has been retreived/not. if BOF property is True then there are no records satisfying the criteria.

Also change this statement

List1.AddItem rscombo.Fields("item_code")

or

List1.AddItem rscombo!item_code

1. ENSURE THAT THERE WILL BE NO SPACES IN ANY OF THE "ITEM_CODE" VALUES.
2. YOU MUST BE SURE THAT THE FIRST LETTER IS DEFINITELY AN ALPHABET "P" AND THE REMAINING PART OF THE FIELD LOOKS LIKE A NUMBER WITHOUT ANY OTHER CHARACTERS.
3. CONSIDER THE SIZE OF THE FIELD FIRSTLY CHECK THE SIZE OF THE FIELD "ITEM_CODE"

U CAN USE THIS FOLLOWING QUERY

Private Sub Combo1_Click()

    Dim nm As String
    Set rscombo = New Recordset

    Select Case Combo1.Text
        Case "Production Consumable"
            'In this query replace 10 with a value equal to (size of your ITEM_CODE field - 1)
            rscombo.Open "SELECT MAX(MID(PQUERY.ITEM_CODE, 2, 10)) AS MAXID FROM PQUERY", con, adOpenDynamic, adLockOptimistic
            MsgBox (rscombo.Fields(0))
            'Here rscombo!MAXID is the last number. To show the next required number
            'just add 1 to it and display. follow the same logic for others also
            List1.AddItem rscombo!MAXID + 1

        Case "Maintenance Consumable"
            rscombo.Open "select * from mquery", con, adOpenDynamic, adLockBatchOptimistic

        Case Else
            rscombo.Open "select * from pquey", con, adOpenDynamic, adLockOptimistic
    End Select
End Sub

IF YOUR ITEM_CODE FIELD HAS MULTIPLE TYPES OF VALUES LIKE "P199", "S23", "S76", "U876" U HAVE TO MODIFY THE QUERY AS BELOW

rscombo.Open "SELECT MAX(MID(PQUERY.ITEM_CODE, 2, 10)) AS MAXID FROM PQUERY WHERE LEFT(PQUERY.ITEM_CODE,1) = 'P' ", con, adOpenDynamic, adLockOptimistic
'OR
    rscombo.Open "SELECT MAX(MID(PQUERY.ITEM_CODE, 2, 10)) AS MAXID FROM PQUERY WHERE LEFT(PQUERY.ITEM_CODE,1) = 'U' ", con, adOpenDynamic, adLockOptimistic

Case Else
    rscombo.Open "select item_code from production  WHERE item_code is not NULL  and  LEFT(Production.ITEM_CODE,1) = 'P' order by item_code ", con, adOpenDynamic, adLockOptimistic
'U need not write rscombo.MoveFirst b'cos 
'the recordset when opened will be positioned at the First Record only
'    rscombo.MoveFirst
    Do Until rscombo.EOF
        List1.AddItem rscombo.Fields("item_code")
        rscombo.MoveNext
    Loop
    Exit Sub
End Select

If any leading spaces may be in the item_code field then use the trim function.

Case Else
    rscombo.Open "select item_code from production  WHERE item_code is not NULL  and  LEFT(Trim(Production.ITEM_CODE),1) = 'P' order by item_code ", con, adOpenDynamic, adLockOptimistic
'U need not write rscombo.MoveFirst b'cos 
'the recordset when opened will be positioned at the First Record only
'    rscombo.MoveFirst
    Do Until rscombo.EOF
        List1.AddItem rscombo.Fields("item_code")
        rscombo.MoveNext
    Loop
    Exit Sub
End Select

since u have both upper case and lower case alphabets in the item_code use UCase in the query for comparison.

Case Else
    rscombo.Open "select item_code from production  WHERE item_code is not NULL  and  LEFT(UCase(Trim(Production.ITEM_CODE)),1) = 'P' order by item_code ", con, adOpenDynamic, adLockOptimistic
'U need not write rscombo.MoveFirst b'cos 
'the recordset when opened will be positioned at the First Record only
'    rscombo.MoveFirst
    Do Until rscombo.EOF
        List1.AddItem rscombo.Fields("item_code")
        rscombo.MoveNext
    Loop
    Exit Sub
End Select

UCase() function converts any alphabet to its Upper Case. If the database is SQL Server use Upper()
