becomes decayed. The fruit drops to the ground and the worms, 

 which will curl up and snap themselves an amazing distance, at 

 once burrow into the ground where they pupate and soon emerge 

 as a fly. 



They affect almost all kinds of fruit and vegetables except pine- 

 apples and bananas, which are the only fruit admitted from Hawaii 

 on this account. 



The Mexican Orange Maggot has almost the same habits as the 

 Mediterranean Fly, and infests oranges, sweet limes, mangoes, 

 achras sapotes, peaches, guavas and plums. All of these fruits 

 from Mexico are excluded from California and Arizona. 



These pests should be watched for very carefully in every orchard 

 and wherever fruit is found. If you find fruit or vegetables filled 

 with maggots, do not throw them away and thus give the worms 

 a chance to go into the ground and mature and start the pest here. 

 Wrap the fruit up to prevent their escape, and send to the nearest 

 Horticultural Inspector for investigation. It is a serious matter. 



APHIS OR PLANT LICE 



Woolly Aphis 



( S chizoneura lanigera) 



. Black Peach Aphis 



(Aphis persicae niger) 



Orange Aphis 



(Aphis gossipi) 



The aphis family is probably the most widely distributed and 

 most prolific of any plant eating insects known, and were it not 

 for many very active parasites, and the work of predaceous insects, 

 we should find it difficult to bring to maturity any plant life. 



However, the above mentioned friends work hard for us and most 

 kinds of the aphis do us comparatively little damage. 



We have aphis known as the orange, the green rose, the brown 

 or black, the melon, the black peach, the woolly aphis, and many 

 more of less importance. 



The Black Peach, the Melon and the Wolly Aphis are the ones 

 most important for the fruit grower to control, as the care of 

 orange trees for other pests almost always subdues the aphis on 

 them. The Melon Aphis is now managed by placing colonies of 

 the common spotted and red ladybirds in the melon patch. They
