Onions are chiefly damaged by thrips. Thrips tahaci is numerous, 

 but is easily controlled by tobacco extract and whale-oil soap. 



Parsley is attacked by Papilio poh/xenes and by cutworms. 



Peas are damaged by Acyrthosiphon {Macrosiphum) pisi and in 

 dry weather by the mite, Tetranyclius telarius, which can be controlled 

 by heavy sprinkling or by sprays of sulphur dust. Bruchus {Laria) 

 pisorum attacks dried peas. 



Potato pests include the Coreid, Acanthocephala feniorata, which 

 attacks early potatoes and is best picked off by hand. It is abundant 

 on thistles, which should not be allowed to grow near a potato crop. 

 Leptoglossiis phi/Uopiis, Lachnosterna sp., and Ligyrus gihhosus are 

 minor pests. 



Squash plants are attacked by the caterpillars of Melittia satyrini- 

 formis, which bore into the stem, and by the squash-bug, Anasa 

 tn'stis, for which the most satisfactory control is hand-picking. 



Strawberry pests include the Lygaeid, Pamera vincta, Say, which 

 causes the berries to wither. This insect is very abundant on wild 

 spurge (Euplwrhia sp.), which may be its native host- plant ; this 

 weed should be destroyed in the vicinity of strawberry beds. 

 Pamera hilohata is also found, as well as red spiders, thrips — including 

 FrankUnielh bispinosus project us and Leptothrips mali, and the bug, 

 Corimelaena publicaria, which can be driven away by a spray composed 

 of a tablespoonful of crude carbolic in 2 U.S. gals, water. Hallica 

 ignita (flea-beetle), and Gryllus assimilis (field-cricket), are minor pests. 



Sweet potatoes are attacked by Prodenia spp., which should be 

 sprayed \\dth lead arsenate, or surrounded wdth Kansas bait ; Bemesia 

 inconspicua causes considerable damage to late crops, the larvae 

 sucking the sap from the leaves. They should be killed, when young, 

 by a strong soap solution or kerosene emulsion. Cylas formicariiis 

 attacks the roots or stored tubers. All potatoes infested by this weevil 

 should be used only for stock-feeding. 



Tomatoes are chiefly damaged by Heliothis obsolefa, for the control 

 of which the plants should be sprayed, while the fruit is still very 

 small, with 2 or 3 lb. of lead arsenate or 1 lb. of zinc arsenite to 50 U.S. 

 gals, of water. Maize is recommended as a trap-crop sown between 

 every 10 to 20 rows of tomatoes ; this should be timed to have 

 developed young silk when the first tomatoes are ripening and must 

 be cut before it has matured sufficiently to become unattractive to 

 these caterpillars. Minor tomato pests include Frankliniella bispinosus 

 prqjectus, Protoparce (Phlegethontius) quinquetnacfidata and P. sexta 

 (which are largely controlled by Apanteles congregatus), Celerio lineata, 

 and the whitefly, Aleurodes tabaci. 



Watermelons are infested by Aphis gossypii, for which the suggested 

 controls are spraying with Black-leaf 40 and soap solution, fumigating 

 with tobacco, or dusting with tobacco dust when the young plants 

 are wet with dew, and clean culture.
