چکیده
A study was carried out to determine the effectiveness of newly synthesized chemical ‘4-[3-(4-biphenylyl)-1, 6-dihydro-6-iminopyridazin-1-yl] butyronitrile hydro bromide against beanaphid, Aphis craccivora, under six treatments: T1 (20 ppm), T2 (40 T3 (60 T4 (80 T5 (100 and untreated control T6. Aphid numbers peaked in January it zero February. The best efficacy administered doses found followed by T5, T4, T2, respectively. aphid abundance different weeks (F= 1.89; p<0.05) treated 3.19; p< 0.02) were significantly varied among plants. population showed a positive correlation with temperature (r = 0.48) 0.33) negative -0.32), (-0.24), (-0.20), T6 (- 0.24). Whereas, aphids positively correlated humidity 0.46), 0.40), 0.18) negatively -0.53), -0.40), -0.52). produced most vigorous fruits, while lowest. Bangladesh J. Zool. 50 (2): 261-272, 2022

Crystal structure of 4′-{[4-(2,2′:6′,2′′-terpyridyl-4′-yl)phenyl]ethynyl}biphenyl-4-yl (2,2,5,5-tetramethyl-1-oxyl-3-pyrrolin-3-yl)formate benzene 2.5-solvate
The title compound, C44H35N4O3·2.5C6H6 (1), consists of a terpyridine and a N-oxylpyrroline-3-formate group separated by an aromatic spacer, viz. 4-(phenyl-ethyn-yl)-1,1'-biphenyl. It crystallized in the triclinic space group P-1 with two and a half benzene solvate mol-ecules (one benzene mol-ecule is located about an inversion center), while the di-chloro-methane solvate (2) of the same mol-ec...
متن کاملDistribution and Economic Importance of Aphis (aphis) Craccivora Koch, 1854 (aphidini: Aphidinae: Aphididae: Hemiptera) and Its Food Plants in India
The black bean aphid, Aphis craccivora was described by Koch in 1854 from Germany. Recently, the genus Aphis Linnaeus, 1758 is subdivided into 6 subgenera : Aphis (s.s.), Bursaphis Baker, 1934, Iowana Hottes, 1954, Maculaphis Zhang and Zhang, 2002, Pseudoprotaphis Kadyrbekov, 2001, Toxoptera Koch, 1856 and Zyxaphis Knowlton, 1947 (Favret, 2016). Aphis craccivora is kept under subgenus Aphis. In...
متن کاملBiology and Demographic Growth Parameters of Cowpea Aphid (Aphis craccivora) on Faba Bean (Vicia faba) Cultivars
The performance of cowpea aphid, Aphis craccivora Koch. (Hemiptera: Aphididae), on five faba bean, Vicia faba L. (Fabales: Fabaceae) cultivars was evaluated. Colony development, biology, and demographic parameters were studied to measure the cowpea aphid performance. Two methods, whole plant and detached leaf, were used in these experiments. After 14 d , the number of apterous adult, nymphs, an...

In the title mol-ecule, C(24)H(20)N(2)O(4), the five-membered oxadiazole ring is nearly planar (r.m.s. deviation = 0.053 Å) and the phenyl ring of the biphenyl unit attached to it forms a dihedral angle of 73.2 (1)°; the other phenyl ring is close to coplanar with the oxadiazole ring [dihedral angle = 6.2 (2)°].

In the title compound, C21H24O5, the dihedral angle between the benzene rings is 19.57 (15)°. In the crystal, the mol-ecular arrangement makes up head-to-head centrosymmetric dimers assembled by pairs of O-H⋯O bonds; this arrangement builds a graph-set ring motif of R (2) 2(8). The dimers are linked into a tape running along the b-axis direction through C-H⋯O inter-actions. The packing is furth...
