Identification and life history of aphids associated with chili pepper crops in southwestern Colombia
Viral diseases, transmitted by aphids, are the most limiting problems in chili pepper crops. Understanding the demographic features of these aphids, may thus assist the design of better disease control strategies in chili peppers. Aphid species found in chili pepper crops in southwestern Colombi...

Viral diseases, transmitted by aphids, are the most limiting problems in
chili pepper crops. Understanding the demographic features of these
aphids, may thus assist the design of better disease control strategies in
chili peppers. Aphid species found in chili pepper crops in southwestern
Colombia were identified as Aphis gossypii Glover and Myzus persicae
(Sulzer). An array of life-history parameters of both aphid species were
investigated at 25 ◦C ± 0.5, 75 ± 1.75 % r.h., L12:D12, and LS 5-Light
Storm in chili pepper crops. Both aphid populations consisted only
of parthenogenetic females, showing a similar average development
time—from the first nymphal instar to the post-reproductive adult—,
female longevity, and daily average fertility values. The length of the
reproductive period was higher for M. persicae. A. gossypii reached its
adult state significantly faster than M. persicae. The intrinsic rate of
population growth (rm
) was lower for M. persicae (0.39) compared to A.
gossypii (0.43). Results showed a potential for fast population growth
in both species, which would enhance their role as virus vectors. The
information acquired is essential to develop pest management initiatives
for these two aphid species |
