Non host alternating life cycle (monoecious or autoecious) in which the
aphid feed and reproduce on only one host plant during the whole year 2.
Aphid species richness that is 2 to more than 2 host plant species infested per
aphid species (Table.
Lamiaceae) seed extract, had significant adverse effects on the honeydew excretion frequency and honeydew production of cotton
aphid.
In Rahimyar Khan, three hot spots of
Aphid, and two hot spots of armyworm while in Rajanpur one hot spot of
Aphid were observed.
In Rahimyar Khan, two hot spots of white fly,
Aphid (6), and armyworm (5) were reported.
The
aphid means were subjected to exploratory analyses to assess the assumptions of the normality of residuals, homogeneity of variance of the treatments, and additivity of the model to allow for parametric tests.
The present study was designed to determine integrated effect of synthetic insecticides and nitrogen fertilizer on
aphid population in canola crop.
All allelopathic water extracts investigated in our studies had a significant effect on
aphid mortality (Table 2).
Aphid abundance was negatively correlated with parasitoidism rates in both distances (25 m and 525 m).
Biology of Transverse beetle, Coccinella transvarsalis Fabricius reared on Akk
aphid, Aphis nerii under laboratory conditions.
50) resulted in a mortality above 50 % of the
aphid after 48 hr of treatment but none of them was as toxic as Actara insecticide did (90.
balteatus was determined by offering them four
aphid species B.
