    id_insumo,nome_comercial 
FROM

You can use jQuery.ajax() to perform this procedure.

Example

var request = $.ajax({
    url: "pagina_que_fara_a_consulta.php",
    type: "POST",
    data: { sua_variavel : conteudo },
    dataType: "html"
});

request.fail(function( jqXHR, textStatus ) {
    alert( "Request failed: " + textStatus );
});
