28 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1934 
eggs had developed. Undoubtedly in many of the groves the flies were taken 
before they had had an opportunity for oviposition. 
The inclusion of Willacy County, the citrus area of which is a continuation of 
that in Cameron and Hidalgo Counties, in the regulated area when the quarantine 
was made effective in 1927, was justified by the taking of 3 adult Mexican fruit 
flies in 3 groves in that county during the fiscal year. These were the first 
specimens of A. ludens taken in this county. 
OTHER ANASTREPHA 
In addition to the 280 adult Anastrepha ludens, several other kinds of fruit 
flies of the same and related genera were taken in the traps. These included 511 
A. serpentina Wied., 312 A. pallens Coq., 52 Toxotrypana curvicauda, 51 A. species 
X, 31 A. fraterculus auct., 16 A. species Y, and 1 A. striata Schin. The details 
are shown in table 8.

There was a considerable increase over the preceding year in the number of 
A. serpentina, A. fraterculus, and A. pallens taken in the traps. Only 1 specimen 
of A. serpentina and 2 of A. fraterculus were taken during the fiscal year 1932. 
So far as is known the species X and Y are new to science, whereas the A. striata 
was the first adult of this species taken in the continental United States. Whether 
these various species are feeding on citrus fruits, whether they have a native 
brush host, or whether they are a part of the northward migration of Anastrepha 
in Mexico is problematical. The specimens of A. striata, taken in the Mission 
district, undoubtedly drifted across the Rio Grande from Reynosa, Mexico, as 
guavas infested with this species are frequently observed in the Mexican markets. 
Papaya fruit flies (Toxotrypana curvicauda Gerst.), two specimens of which had 
previously been taken in the Weslaco district, were captured in fairly large num- 
bers throughout the valley. 
INSPECTIONS 
The trapping operations planned as a supplement to the regular inspection of 
fruit for larval infestations proved so effective, through the use of the glass traps, 
that this phase of the work was given precedence in determining the extent of 
infestation for the year. Approximately 5,500 glass traps were in operation in 
the Texas groves from October 1933 to June 1934. A total of 245,615 inspections 
were made of these traps. An additional 3,500 glass traps were purchased near 
the end of the year, making a total of about 9,000 traps that will be in use during 
the next year. 
In addition to the trapping operations, 12,358 regular grove inspections were 
made for the purpose of enforcing the regulations and locating larval infestations 
in the fruit. Intensive inspections were made of the fruit in those groves in 
which adult fruit flies were taken in the traps.
