 CABBAGE HAIR-WORM OR CABBAGE SNAKE (Mermis albicans)
 This whitish, thread-like worm (fig. 77), which sometimes
 grows to be 2 to 9 inches long, is frequently found in cabbage
 heads. It is an internal parasite of grasshoppers and cater-
 pillars and it gets into the cabbage by crawling out of infested
 insects. It is therefore a friend of the grower. In spite of its
 repulsive looks and the many stories which are told of its pois-
 onous nature, it is entirely harmless to mankind.

 SOUTHERN SQUASH BUG (Anasa armiger)
 This insect sometimes attacks cabbage and collards. It
 breeds on these plants, as eggs and nymphs are found there.
 OTHER CABBAGE PESTS
 The following named insects also infest cabbage in Florida:
 Blister-beetles (see under beets, page 134) ; flea-beetles (see un-
 der beets, page 136) ; tarnished plant-bug (see under celery,
 page 149); onion thrips (see under onions, page 172); wire-
 worms (see under corn, page 153) ; nematodes (see root-knot
 under general garden pests, page 128) ; and grasshoppers (see
 under general garden pests, page 122) ; serpentine leaf-miner
 (see under cowpeas, page 162).

 CANTALOUPE
 The insect pests of this crop are identical with those of
 cucumbers. (See cucumbers, page 163).

 CARROT
 The common insect pests of this crop are: Cutworms (see
under cabbage, page 137) ; garden aphid (see cabbage plant-lice
under cabbage, page 144) ; black blister-beetle (Epicauta penn-
sylvanica) (see blister-beetles under beets, page 134; celery
caterpillars (see under celery, page 150) ; and carrot-beetle
(Ligyrvs gibbosus) (see May-beetles under potatoes, page 178).

 CELERY
 TARNISHED PLANT-BUG (Lygus pratensis)
 This bug (fig. 79) is very common the country over in
gardens where it frequents blossom heads and other very young
and tender herbage and even the tender shoots of trees. The
succulent stalks of the celery plant afford a very acceptable
feeding place. In addition to stunting the growth of the plant,
