Summary: | Tuta absoluta
Meyrick quickly developed into a significant pest of tomatoes worldwide. While the mirid bugs
Macrolophus basicornis
(Stal),
Engytatus varians
(Distant) and
Campyloneuropsis infumatus
(Carvalho) prey on this tomato borer, their biology have not been well characterized. Using a mixture of
T. absoluta
eggs and larvae as food on tomato, mirid life histories were studied. Nymphs and adults successfully used
T. absoluta
as prey, although significant differences in biology of the species were observed.
Campyloneuropsis infumatus
and
M. basicornis
were quickest and slowest to become adult at 16 and 19 days, respectively. Nymphal survival was high and varied from 70 to 75 %. Female biased sex ratios were observed for
C. infumatus
(0.80) and
M. basicornis
(0.71), but not for
E. varians
(0.56). Intrinsic rates of increase for
C. infumatus
,
E. varians
and
M. basicornis
were 0.11, 0.10 and 0.11 respectively. Our results indicate rapid development and population increase of these three mirids, making them interesting candidates for biological control of
T. absoluta
on tomato. |
