ONE INSECT AND ONE DISEASE 97 



when they eat their way out and hibernate 

 in the ground in chrysalis form until spring 

 when the fly hatches out and begins its annual 

 cycle." 



Imported bulbs of the lower priced cheaper 

 grades may be to some extent infected. A 

 blackish spot the size of a pin's head near the 

 shoulder of the bulb is suspiciously indicative 

 that a grub has entered. If a similar and 

 larger spot is found near the base of the bulb 

 your suspicions are likely to be well founded, 

 for it is customary for these grubs to make 

 the second hole as an outlet for the frass. 



Of course, to be on the safe side, you will 

 destroy infected bulbs with their inhabitants 

 and this is not any sacrifice, because only 

 healthy bulbs will give perfect flowers. Where 

 the flies do appear they are trapped on plates 

 containing thick molasses in the centre with 

 edges smeared with honey to attract them. 



Of course, there are some other minor di- 

 seases and troubles, but th,eir total result 

 amounts to practically nothing. As affecting 

 the gardener, for whom this book is written 

 they may be ignored, and so are dismissed 

 with this bare reference.
