Pseudonapomyza gujaratica Shah, 1980
Because of the lack of material this species could not be included into the IdentifyIt module. The following description is taken from the original description.
According to the author (Shah, 1980) gujaratica is closely related to Pseudonapomyza asiatica, but differs in the shape of the male genitalia, the host plant composition and the feeding habit.
DESCRIPTION (after Shah, 1980)
Head: Frons not projecting above eye in lateral view; slightly narrower than the eye; four almost equidistant frontorbital bristles; upper three almost equal and longer than the lowermost; third antennal segment longer than broad, with distinctive angle at upper corner.
Mesonotum with three dorsocentral bristles gradually increasing in size, of these one presutural.
Wing: Costa reaching only to r 4+5; second costal section conspicuously short and about 1 1/2 times length of the fourth.
Color: Head, mesonotum and abdomen mat black; squamae and fringe silvery; wings almost transparent; veins completely black; halteres milky white.
Male genitalia shown in Pseu gujaratica aedeagus.pct.
BIONOMICS
The whitish linear leaf mine can be found at any part of the leaf. Normally only one larva is found in one mine. Pupation takes place in the soil (Shah, 1982). The life cycle in Gujarat is completed in 3-4 weeks, females lay on average each 42 eggs.
HOST PLANTS
Zea mays L. (maize), Sorghum vulgare (Sorghum). Since both plants are not native to India, some additional wild host should be expected.
DISTRIBUTION
Only known from India: Gujarat. There the species was found to be abundant.
ECONOMIC IMPORTANCE
The main host was found to be maize (Shah, 1980). The same author concluded that Pseudonapomyza gujaratica does not cause important damage. Apparently the population were controlled by some insecticides which had been applied against other insects. For a really qualified statement about the pest status is still too premature because the species was very recently described and their distribution is insufficiently understood.
