Insects and diseases of vegetables, M. T. Cook and W. T. Horne {Estac. 

 Cent. Agron. Cuba Bui. 12, English Ed., pp. 28. pis. 8). — This is a preliminary 

 report on the insect pests and diseases of vegetables in Cuba. 



There are said to be several species of crickets which do considerable damage, 

 among the most troublesome being GnjUodes poeyi, which cuts twigs and leaves 

 from small plants and frequently cuts the very young plants at the surface of 

 the ground. In many cases entire crops are destroyed. The changa {Scaptcr- 

 iscus didactglus) does some damage by cutting young plants, while the bibi- 

 jagua {Atta insularis) is a very troublesome ant. Plant lice are reported to 

 have been abundant on many vegetables, such as turnips, radishes, beans, cab- 

 bages, cucumbers, etc. Thrips have caused considerable injury to a number of 

 plants, particularly beans and onions. 



The red spider has attacked eggplants, tomatoes, and other plants, while a 

 species of Eriophyes attacks the tomato, causing a thickening qf the stem and 

 an excessive growth of plant hairs, resulting in a stunted plant. The cachazudo 

 {FcJtia anncra) is considered the worst enemy of tobacco. Pieris monuste has 

 been specially destructive to rape and cabbage. Plutella macuUpennis are 

 abinidant on cabbage and rape and cause considerable loss. Protoparcc Carolina 

 feeds to some extent upon tomatoes, but not in sufficient numbers to do much 

 injury. The larvae of DUophonota ello feed upon young yuca or cassava, and 

 sometimes occur in sufficient numbers as to be injurious to the growing crop. 



Pega-pega, the leaf folder {Micromima olivia) is specially destructive on 

 tobacco in the seed bed, also attacks several vegetables, particularly tomatoes, 

 and has been found on the eggplant and Solanum torvum. Lineodes integra 

 was observed in December, 1904, feeding upon eggplants in the Matanzas prov- 

 ince. The eggplant weevil {Anthononius varipcs) has been observed in the 

 vicinity of tlie station, where it is apparently the worst enemy of the eggplant. 



Of the bean insects, a small green leaf hoi)per is thought to be the most 

 harmful. A species of Diabrotica and lepidopterous larvne of several kinds are 

 also injurious to beans. The larvai of Lagocheinus ohsoletus have been found 

 to some extent on the old canes of yuca and cassava, but apparently do not 

 attack the plant until quite old, and do not cause a great amount of injury. 

 Either the pasador of the tobacco, or a species very similar to it, caused some 

 trouble by feeding upon the tubers of potatoes. The pasador of the eggplant 

 {Anthononius sp.), a stem borer of a different family, does some harm by short- 

 ening the pi-oductive life of the plants. The tetuan {Cylas formicarius) fre-
