Script Error

My script runs fine for awhile but runs into these errors and the site crashes eventually

PHP Warning: Missing argument 2 for wpdb:repare(), called in /home/admin/web/web.com/public_html/scrape/import_web.php on line 155 and defined in /home/admin/web/web.com/public_html/wp-includes/wp-db.php on line 1291, referer: http://www.web.com/scrape/import_episode.php?start=237

These are the lines the errors speak of

Line 155
$query = $wpdb->prepare("UPDATE 1zmarz_animes SET episode_created='1' WHERE id='".$importid."'");

Line 9
$query = $wpdb->prepare("SELECT id, anime_name2, wordpress_id FROM 1zmarz_animes WHERE wordpress_created='1' AND episode_created='0' ORDER BY id ASC LIMIT $start,1");

Line 35
$query2 = $wpdb->prepare("SELECT * FROM 1tmarz_episodes WHERE animes_id='".$importid."' ORDER BY episode_name3 ASC");

How do i fix this
