ENCYCLOPEDIA OF PRACTICAL HORTICULTURE 



Four-Spotted Bean Weevil 



Bruchus quadrimaculatus 



An old enemy of cow peas. It also 

 works in the common bean and, like the 

 common bean weevil, it works indefinitely 

 in the stored seeds until nothing ot value 

 is left. As this beetle is larger than the 

 bean weevil, its work is comparatively 

 rapid. 



Like the bean weevil, this creature 

 starts work in the field, coming into the 

 granary with the harvested beans, or it 

 may gain access after the beans have been 

 stored away. 



Bemediefi 



Fumigation of the seed during warm 

 spells with carbon bisulphid is the best 

 remedy thus far discovered.

Ladybird 



Epilachna corrupta, Muls. 



The beetles belonging to the ladybird 

 family are quite common in this section. 

 They are small oval or hemispherical in 

 shape and are red and brown with black 

 spots or black with red or yellow spots. 

 These beetles are divided roughly into 

 two classes, beneficial and injurious. The 

 beneficial species feed on plant lice and 

 scale insects. The ladybird is trouble- 

 some throughout New Mexico and occa- 

 sionally it becomes very injurious, espe- 

 cially to the bean crop. This beetle de- 

 vours all parts of the bean plant in both 

 the larval and adult stages. The yellow- 

 ish brown eggs are laid in clusters on 

 the under surface of the leaves. 



The larvae has a yellow color and is 

 covered with ugly branched spines. The 

 matured beetle is light yellowish brown 

 with eight black spots on each wing 

 cover. This beetle is the one locally 

 known as La chinche del 'frljol by the 

 Mexican bean growers. The insect win- 

 ters over in the adult stage and so tar 

 as it is known there is but one brood a 

 year. It seems that in New Mexico the 

 wintered over beetles appear about the 

 last of June to the middle of July and 

 the generation from these is developed in 

 August and September. 



Remedies 



By judiciously using Paris green and 

 arsenate of lead many ot the larvae and 

 adults can be killed. Greater care should 

 be taken when using Paris green, since 

 it is liable to injure the foliage. Kero- 

 sene emulsion is sometimes used with 

 quite a degree of satisfaction. In small 

 gardens hand picking of the first beetles 

 in the summer and destroying the eggs 

 may aid considerably in reducing the 

 number of the late brood. Clean culture, 

 as destroying all weeds and rubbish in 

 the field, fall plowing, and harrowing 

 would undoubtedly reduce the number of 

 adults that will winter over. As there 

 seems to be but one brood and this is 

 most troublesome to the late crop the 

 injury could be materially reduced by 

 planting the beans as early as possible.
