Effect of host plants nutrients, antioxidants, and phytochemicals on growth, development, and fecundity of Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae)
The composition of nutrients among food plants determines the extent of larval development in insects. The objective of the study was to determine the effect of plant nutrients on growth and development of Spodoptera litura larvae subjected to five different food plants namely, Brassica oleracae, Ni...

Zusammenfassung: | The composition of nutrients among food plants determines the extent of larval development in insects. The objective of the study was to determine the effect of plant nutrients on growth and development of
Spodoptera litura
larvae subjected to five different food plants namely,
Brassica oleracae, Nicotiana tabacum, Ricinus communis, Gossypium hirsutum,
and
Arachis hypogaea
. The plant nutrient content, total moisture, ash, fibre, lipid, protein, and carbohydrate were evaluated. Results show moisture and crude protein contents were high in
B. oleracea
, (24.66 ± 1.15%, 16.33 ± 0.57),
N. tabacum
(21.66 ± 1.52%, 16.33 ± 1.53), and
R. communis
(16.33 ± 0.57%, 15.66 ± 1.57). High ash content was present in
G. hirsutum
(16.66 ± 1.45%),
A. hypogaea
(17.33 ± 1.90%), and lipid content was significantly higher in
A. hypogaea
(0.4 ± 0.02%). Whereas
G. hirsutum
has a have high level of fibre content and low level of crude protein content (21.33 ± 0.01, 11.00 ± 1.00%). Carbohydrate levels show no significant difference in all types of plant extract. Phytochemical analysis of five host plants showed high phenol content was observed in
R. communis
,
G. hirsutum
, and
A. hypogaea
, and high flavonoid level in
G. hirsutum
. A higher antioxidant level was observed in
R. communis
(36.66 ± 1.52). These plant nutrients and phytochemicals significantly affected the development growth of
S. litura. R. communis
fed
S. litura
larvae shows a survival rate, 94.33% was significantly higher. Egg to adult development duration was low 21.8 ± 0.1 days, for larvae reared on
R. communis
as compared to other plants. Higher oviposition was observed for larvae fed on
B. oleracea
,
N. tabacum
, and
R. communis
leaves. The larval length, pupal length, pupal weight, female fecundity, adult longevity and utilization of food were significantly higher in
R. communis
fed larvae. The presence of host plant
R. communis
in the field needs to be considered to avoid plant pest infesting. |
