The third main body region of the aphid
, consisting of eight segments, is pale without dark bands.
species were classified according to Remaudiere and Remaudiere (1997) and Nafria (2013).
2013) reported LC50 values of neem, eucalyptus, and laurel essential oils on cotton aphid
, Aphis gossypii Glover (Hemiptera: Aphididae), of 5,389, 9,515, and 13,730 mg/L, respectively, which were higher than the LC50 values obtained in our study.
In Lodhran, officials witnessed three hot spots of white fly, Aphid
(2), Thrips (2), and armyworm (4) while two hot spots of Aphid
were reported from Bahawalpur.
In Bahawalnagar, six hot spots of white fly, Aphid
(5), Thrips (4), and armyworm (2).
The assessments were performed on a weekly basis, and the aphid
species were identified using a guide developed by Salvadori and Tonet (2001).
Application of non-chemical control tactics keeps aphid
population below economic injury level.
mortality caused by allelopathic water extracts was presented in the form of bar graphs fitted with vertical standard error bars.
abundance and parasitoidism rates in crop edge and interior were not affected by distance from adjacent forest edge (Fig.
The collected aphid
was transformed into two ways (i) Frozen aphid
and (ii) Dried aphid
Even though that the five used oils showed significant mortality to the aphid
at a concentration of 1000 ppm compared with the negative control, DMSO solution, but none of them was as toxic as Actara insecticide did after 24 and 48 hr of treatment (Table 1).
Petri dishes were labeled properly and transferred in the rearing cages of (32A-30A-30 cm) dimensions the crop plants or branches infested by individual aphid
species were kept in cages to ensure the presence of prey species.
It was observed that BARD-699 cultivar showed comparatively high resistance with minimum aphid
I turned over a couple of affected leaves and found the culprits - aphids
had moved in.
I turned over a couple of affected leaves and found the culprits - an extended family of aphids
had moved in.
