240 BUREAU OF PLANT QUARANTINE [July-Sept. 
Feru 
The fruit-fly survey (Feb. 0-10 and Mar. 8-Apr. 6), in the Republic of Peru 
was started in the Tacoa area in February l ( .)o2, when the neighboring dis- 
tricts of northern Chile were being surveyed, and taken up again on March 
8 from Lima. In addition to the Tacna area in the southern part of Peru,, 
the section from Ilo to the upper Moquegua Valley was covered in this part 
of the country, also the northern and central regions. This widespread field 
of operation was made possible by the excellent and economical airplane trans- 
portation available in Peru, and the fairly good system of roads extending 
from the coast to the mountains in the central region surrounding Lima and 
Callao. 
Districts visited in the northern section were Chiclayo, Lambayeque, San 
Jose, Pimentel, Monsefu, and Farrinafe. In central Peru those visited were 
Lima and vicinity, Malambo, Magdalena, Miraflores, Surco, the Rimac Valley 
which includes La Molina, Chosica, Santa Eulalia, etc., and the Chillon Valley. 
Points visited in southern Peru included the Tacna Valley from Piedra Blanca 
to a section below the town of Tacna, and the Moquegua Valley, which in- 
cludes the sections of Moquegua, Estuguina, and Samegua. 
Grapes and pineapples were the only fruits grown on large extensive areas 
in the country, but there was quite a variety of tropical and subtropical fruits 
grown on small holdings. The following fruits were examined in the fields 
and public markets of Peru: Bananas, plantains, grapes, pineapples, coffee 
berries, apples, pears, quinces, peaches, guavas, cherimoyas, figs, soursops, 
loquats, pomegranates, mangoes, sapodillas, Lucuina fruits, avocados, rose 
apples, cattleya guavas, chili plums, Barbados cherries, Jamaica plums, apricots, 
oranges, lemons, limes, mamey apples, Inga pods, papayas, passion fruit, and 
palillos. Vegetables seen were melons, cucumbers, tomatoes, peppers, egg- 
plants, tree tomatoes, string beans, potatoes, sweetpotatoes, onions, beets, 
carrots, turnips, cauliflower, lettuce, cabbage, etc. 
Fruit-fly infestations were found at 19 different points, reaching from the 
Department of Lambayeque in the north to the Department of Tacna in the 
south inclusive. In the Rimac Valley near the city of Lima there was noted 
the heaviest infestation encountered in the entire survey of South America 
and the West Indies. 
A total of 2,101 larvae and puparia of Anastrepha spp. were taken in the fol- 
lowing 17 hosts: Apple, Barbados cherry, cherimoya, guava, cattleya guava. 
purple hog plums. Inga feuillei, loquat, Lucuma sp„ mango, olive, palillo, peach, 
pear, pomegranate, rose apple, and quince. One hundred and fifty-six adults of 
Anastrepha spp. were collected on 15 hosts as follows: Apple, avocado, banana, 
bird excreta, caracucha (?), cattleya guava, cherimoya, common guava, grape. 
Inga feuillei, loquat, mango, pear, rose apple, and quince. Anastrepha distans 
was taken on pomegranate. In addition to these 87 adults of Anastrepha spp. 
were reared from larvae taken out of the following 7 fruits: Apple, Barbados 
cherry, cherimoya, guava. mango, peach, and quince. 
One hundred and twenty-five adults of A. serpentina were collected on eight 
hosts as follows: Cherimoya, coffee, grape, guava, loquat, Lucuma sp., pear, 
and quince, as well as on collectors' bands and clothing, some adults of this 
species also being reared from larvae 1 taken out of Lucuma sp. 
Two hundred and forty-two adults of A. peruviana were collected on 25 fruits, 
etc., as follows: Apple, avocado, Barbados cherry, bitter almond, caracucha 
(?), cherimoya. coffee, fig, grape, guava, purple hog plum, loquat, Lucuma sp., 
mango, morning-glory, olive, orange, palillo, peach, pear, pomegranate, rose 
apple, quince, and soursop; also on collectors' hands and clothing. 
Thirty-eight adults of A. distans were taken on seven hosts, viz, avocado, 
cherimoya, grape, guava, loquat, pomegranate, and mango. 
Eight adults and 70 immature stages of Rhagoletis ochraspis were taken in 
tomatoes and on potato and tomato plants. This very destructive pest is also 
reported as attacking green beans and peppers in Peru. 
In addition to the above there was also collected 1 specimen of Baryplegma 
sp.. and 8 adults of the ortalid (with fruit-fly habits). Pterotacnia (Melieria) 
ftr:< lata on potato plants. 
Noteworthy among the injurious insects other than fruit flies taken in Peru 
were the following: Carpocapsa pomonella (?) in apples, peaches, and quinces; 
PagiocerU8 sp. near rimosua Eich. in avocado seeds; larvae of species of Ole- 
threutidae in string beans and Inga feuillei; larvae of Diaphania sp. in caihua
