You can use the required attribute:

<form method="post" action="">

    <label for="fruits">Choose an option:</label>

    <select name="fruits" required>

        <option value="">------</option>
        <option value="fujiapple">Apple</option>
        <option value="vanillaorange">Orange</option>
        <option value="pandoracherry">Cherries</option>


    <input type="submit" name="submit" value="submit" />

By adding an empty option the form will not be submitted. You could also add a javascript check, but you will always need a server-side validation: you cannot trust what is sent by the client.
