even where they show many indications of attempted oviposition. Thus from a total 

 of 292 such fruits representing 12 lots collected from the ground in Pauoa Valley, 

 Moanalua Gardens, and Nuuanuu Valley, during July and August, only 6 adults were 

 reared. The thicker the skin of the fruit the more difficulty does the adult have 

 in ovipositing successfully.

 and from trees on which fruits had already begun to ripen.

While the common thin-skinned sweet mangoes are badly infested when they ripen, 

 many chutney mangoes and certain highly developed horticultural varieties of eating 

 mangoes are less susceptible to attack, owing, in the one instance, apparently to a 

 greater amount of "turpentine " in the skin, and, in the other, to a much thicker skin. 

 Under forced conditions adults will oviposit heavily in chutney mangoes which, 

 ripening on the tree, escape infestation. Three fruits of a " Chinese " chutney variety x
