Title

Life cycle of Zygogramma bicolorata and its effectiveness as biocontrol of Parthenium hysterophorus in Lamjung, Nepal

Shreesha Thapa Magar; Sneha Dahal; Bardan Devkota Archives of Agriculture and Environmental Science 2025. doi:10.26832/24566632.2025.1003012

Other claims from this paper (16)

Observation Female Zygogramma bicolorata lived longer (43.3 days) than males (37.0 days).
Observation Each female laid an average of 650 eggs during its lifespan.
Observation Egg hatching success was 84.08%.
Observation Pupal recovery was 81.32%.
Observation Adult emergence was 78.69%.
Observation The beetle had four distinct larval instars.
Observation Pupation occurred at 3-5 cm soil depth.
Association Feeding potential varied with developmental stage and beetle density.
Observation Both adults and larvae of Z. bicolorata caused significant defoliation of Parthenium hysterophorus.
Intervention effect Higher beetle densities led to faster defoliation of Parthenium.
Intervention effect Defoliation of Parthenium by five beetle pairs at the seedling stage took 1.13 days.
Intervention effect Defoliation of Parthenium by five beetle pairs at the flowering stage took 6.67 days.
Intervention effect Defoliation of Parthenium by two pairs at the seedling stage took 6.67.
Intervention effect Defoliation of Parthenium by two pairs at the flowering stage took 15.67 days.
Observation Larvae contributed more to defoliation of Parthenium than adults.
Recommendation Z. bicolorata shows strong potential as a biocontrol agent against P. hysterophorus.

Other claims from this paper (6)

Intervention effect At 2 g/kg, C. procera leaf powder caused more than 85% mortality after one day.
Intervention effect At 16 g/kg, leaf powder caused almost complete adult mortality.
Intervention effect At 8 g/kg, leaf extract completely inhibited C. maculatus F1 emergence.
Intervention effect Leaf extract considerably reduced C. maculatus grain damage.
Intervention effect C. procera leaf extract did not affect seed viability.
Recommendation The authors propose C. procera powder as an alternative insecticide for stored cowpea grain.
