Despite the extensive screening of plants for insecticidal properties, only a vanishingly small proportion of the world s species have been examined. Apparently, even some very common kinds of plants have been overlooked Dr. Lichtenstein will discuss his research on natural insecticides in turnips, rutabaga, and other garden vegetables. 

The edible parts of parsnips contain a chemical of insecticidal and strong synergistic nature. This chemical, present in a concentration of about 200 p.p.m., was isolated and identified as 5-allyl-l-methoxy -2, 3-methylene-dioxybenzene or myristicin. Its toxicity to various insects (fruit flies, etc.) was established and compared with pyrethrum and aldrin. A second chemical, identified as 2-phenylethyl isothiocyanate, was found in the edible parts of turnips and rutabaga, which also have been consumed for centuries by humans without obvious harm. 

The wide distribution of this insecticide in other cruciferous crops was investigated later, and the stability and occurrence of this compound were studied. Two cabbage varieties, cauliflower, brussels sprouts, broccoli, kale, mustard, and kohlrabi contained 2-phenylethyl isothiocyanate in various amounts as evidenced by gas-liquid chromatography and bioassay (houseflies and vinegar flies) (Table VII). Insecticidal activities were encountered only with root tissues. Compounds of insecticidal activity, not attributable to 2-phenylethyl isothiocyanate, were found in the edible parts of radish and leaves of turnip, rutabaga, and garden cress. 

Root crops include rutabagas, turnips, and radishes. Spring and summer radishes tend to have small roots, apart from the long white "mooli" types. Winter radishes are much larger. Radishes can also be grown for the peppery seed pods that follow the flowers.

Details of preparation and storage conditions for crops that last well through the winter are given here (seepanel, left). Some other crops can also be stored for shorter periods for example, carrots, parsnips, beets, rutabagas, and celeriac keep well if packed in moist sand or fine leaf mold in shallow trays or boxes. 

Susceptible plants Brassicas, especially turnip and rutabaga also celery, cucurbits, leek, lettuce, onion, parsnip, potato, tomato, and cyclamen. 

Symptoms Young plants wilt or grow poorly, and are easily pulled out of the ground. Established plants may show no obvious symptoms. Damage to root crops (radish, turnip, rutabaga) may make them inedible. Larvae occasionally found inside Brussels sprouts. 

Susceptible plants Cabbage, carrot, cherries, onion, parsnip, plum, potato, rutabaga, and tomato.

Principal dietary sources of vitamin A are milk fat (cheese and butter) and eggs. Since it is stored in the Uver, inclusion of Uver in the diet also provides vitamin A. A plant pigment, carotene, is a precursor for vitamin A and is present in highly pigmented vegetables, such as carrots, rutabaga, and red cabbage.

It has been known for a long time that some foodstuffs, eg, turnips and rutabaga, are goitrogenic because of the presence of progoitrin. This substance is hydrolyzed to goitrin, or (5)-5-vinjI-2-oxazohdinethione [500-12-9] (14), which is goitrogenic when iodine intake is low. 

Rapeseed/Canola belongs to the turnip rutabaga, cabbage, Brussels sprouts, and mustard family of crops that can be grown at low temperatures and moderate humidity. Three species have been grown as oilseeds Brassica napus, known in Europe as rape, oil rape, Swede rape, and Argentine rape B. campestris, known as rapeseed, oil turnip, turnip rape, and Polish rape and B. juncea, known as leaf mustard, brown mustard, Oriental mustard, and Indian mustard. B. campestris was grown in India as early as 2000-1500 BC. 

Fig. 3.13 Neurofibromin signalling in learning. Gi roteirvcoupled receptors are linked to adenylyl cyclase through the a-subunit of the stimulatory G protein, Gs. Activated receptors stimulate adenylyl cyclase to synthesize cyclic AMP (cAMP), which activates the downstream effector, protein kinase A (PKA). Guo ef a/.i 3 show that the neurofibromin protein is required in this pathway for normal odour learning in Drosophila, perhaps by direct interaction with a heterotrimeric G protein or with the adenylyl cyclase encoded by the rutabaga gene (see ref 104 for further information). (This scheme is based on information published in Rg. 1 of ref. 104 and reproduced with permission of the author and Nature.)...

When drying most food products such as rutabagas (S16) or macaroni, the solutions contain a great many soluble materials so that Eq. (17) would not be accurate. In drying welding rod (G4) the data indicate some of this error, and data on food products were even less accurate.
