“…Streibert et al (1988) reported that Diafenthiuron has a relatively low toxicity to beneficial insects. But Amin et al (2014) reported that Diafenthuron was highly toxic to C. septumpunctata as it showed maximum percent reduction (78.93%) after seven days of spray application. Ahn et al (2013) reported that Lufenuron did not show any toxic effect to honeybee and thought to be safe.…”

Field studies were carried out to evaluate the efficacy of four new generation insecticides along with a botanical against mustard aphid (Lipaphis erysimi Kalt.) and their toxicity to coccinellid beetles and foraging honeybees during 2014-15 at Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh. Buprofezin 40 SC was found to be the most effective against aphid offering the lowest aphid population (1.56/ top10cm central twig) at 7 days after spraying (DAS) which was statistically identical to Diafenthiuron 500SC (1.85/ top10cm central twig). Among the treatments, Azadiractin 1EC appeared to be safest to coccinellid beetles and foraging honeybees because it recorded the highest number of beetle (7.50 /5 plants) and honeybee (9.64 /plot/5 min) population at 7 DAS, although honeybee population did not vary statistically with that of Buprofezin 40 SC and Lufenuron 5EC treated plots. Indoxacarb 145SC was found to be the most toxic against honeybees. However, the highest yield was obtained from Buprofezin 40 SC (1.57 t ha -1 ) treated plot although this was statistically identical to that Diafenthiuron 500SC (1.52 t ha -1 ) and Azadiractin 1EC (1.48 t ha -1 ) treated plots.

“…The insect-toxin protein bioassay data were analyzed in one way ANOVA through "Statistix 8.1" and means were separated by Tukey-LSD test with significance level of 0.05 [27]. Standard errors of each concentration were also computed through Microsoft Excel 2010.…”

The present study describes the predicted model and functional characterization of an endochitinase (30 kDa) from corms of Gladiolus grandiflorus. ESI‐QTOF‐MS generated peptide showed 96% sequence homology with family 18, Class III acidic endochitinase of Gladiolus gandavensis. Purified G. grandiflorus chitinase (GgChi) hydrolyzed 4‐methylumbelliferyl β‐d‐N,N′,N′′‐triacetylchitotriose substrate showing specific endochitinase activity. Since no structural details of GgChi were available in the Protein Data Bank (PDB), a homology model was predicted using the coordinate information of Crocus vernus chitinase (PDB ID: 3SIM). Ramachandran plot indicated 84.5% in most favored region, 14.8% in additional and 0.6% in generously allowed region while no residue in disallowed region. The predicted structure indicated a highly conserved (β/α)8 (TIM barrel) structure similar to the family 18, class III chitinases. The GgChi also showed sequence and structural homologies with other active chitinases. The GgChi (50 μg/disc) showed no antibacterial activity, but did provide mild growth inhibition of phytopathogenic fungus Fusarium oxysporum at a concentration of 500 μg/well Similarly, insect toxicity bioassays of GgChi (50 μg) against nymphs of Bemisia tabaci showed 14% reduction in adult emergence and 14% increase in mortality rate in comparison to control values. The GgChi (1.5 mg) protein showed significant reduction in a population of flour beetle (Tribolium castaneum) after 35 days, but lower reactivity against rice weevil (Sitophilus oryzae). The results of this study provide detai.led insight on functional characterization of a family 18 class III acidic plant endochitinase.

“…Bana et al (2014) recorded the minimum population (2.67 and 2.10/10 plants)was recorded in imidacloprid. Amin et al (2014) found that Imidacloprid showed 57.34% reduction in C. septumpunctata population whereas dimethoate 52.77% reduction in larval population of syrphid flies after seven days of spray application. It is concluded that bifenthrin and imidacloprid can be used for the management of mustard insect pests because of their higher efficacy against aphids and leaf miners and less toxicity to beneficial insects.…”

Background: The prime intention of this research work was to assess the effect of synthetic insecticides and bio-pesticide against natural enemies of aphid, Lipaphis erysimi (Kalt.), mainly ladybird beetle Coccinella septumpunctata (Linnaeus) and syrphid fly, Ischiodon scutellaris (Fabricius) in mustard was evaluated. Methods: The field experiment was conducted at Student Research Farm, Department of Entomology, CSAUA and T Kanpur during Rabi season of 2013-14 and 2014-15. Experiment conducted in Randomized block design with three replication and eight treatments. Imidacloprid, deltamethrin, spinosad, fipronil, thiamethoxam, Metarhizium anisopliae and Beauveria bassiana were tested against natural enemies and available population of natural enemies of aphid were recorded before 1 day and after 3, 5, 7 and 14 days of spray application. M. anisopliae and B. bassiana were the most effective with less toxicity against Ladybird beetle and syrphid fly by continuously increasing population after application. Though all the tested chemical insecticides were found toxic to the lady bird beetle and syrphid fly larvae, imidacloprid and thiamethoxam were found relatively safer to other insecticides by recording less mortality after 14 days of spraying during two years testing period. Result: M. anisopliae, B. bassiana, imidacloprid and thiamethoxam may be used for the management of insect pests because of their less toxicity to beneficial insects.
