having consumed it, perishes. And, if it has en- 

 tirely eaten it, the wheat itself 1 perishes ; if 

 however it has only eaten one 2 side of the haulm 

 and the plant has succeeded in forming the ear, 

 half the ear withers away, but the other half remains 

 sound. However it is not everywhere that the 

 wheat is so affected ; for instance this does not occur 

 in Thessaly, but only in certain regions, as in Libya 

 and at Lelanton in Euboea. 



Grubs occur also in okhros s lathyros and peas, 

 whenever these crops get too much rain and then 

 hot weather supervenes ; and caterpillars occur in 

 chick-peas under the same conditions. 4 All 5 these 

 pests perish, when they have exhausted their food, 

 whether the fruit in which they occur be green or 

 dry, just as wood-worms do and the grubs found in 

 beans and other plants, as was said of the pests 

 found in growing trees and in felled timber. But 

 the creature called ' horned worm ' 6 is an exception. 

 Now in regard to all these pests the position makes 

 a great difference, as might be expected. For the 

 climate, it need hardly be said, makes a difference 

 according as it is hot or cold, moist or dry ; and it 

 was the climate which gave rise to these pests 7 ; 

 wherefore they are not always found even in places 

 in which they ordinarily occur. 8

 germination and for keeping well. Some germinate

 favourable to the pest.
