“…However, under the high rainfall regimen, plots treated with either imidacloprid or thiamethoxam resulted in significantly less (P<0.05) PLH damage early in the season (25 Jun) than did all other treatments, but only plots treated with thiamethoxam had significantly (P<0.05) less PLH damage than all other treatments on 7 July. Our data agrees with that of [30], who reported that thiamethoxam provided longer and more consistent protection of snap beans from PLH than did imidacloprid when applied as a seed treatment. They concluded that thiamethoxam had greater physiological activity against PLH than did imidacloprid.…”

“…This could be complemented with a few applications of foliar sprays after five weeks to protect against flower and pods pests such as thrips. This intervention would reduce growers' production costs, and improve human and environment safety (Nault et al, 2004). Considering the level off operation, seed dressing and onward sowing does not result in pesticide dust formation, hence has practically minimal effects on bees and other pollinators.…”

Snap bean (Phaseolus vulgaris L.) farmers rely mostly on insecticides to manage pests and to satisfy the stringent market requirements for insect and blemish-free pods. However, the cost of these pesticides lowers farm incomes. In addition, heavy and wrong use of pesticides could result in residue accumulation, which reduces market access by the farmers. To identify optimal pest control with lower economic risks to farmers, we investigated the effectiveness and profitability of different insecticides and insecticide formulations against bean fly (Ophiomyia spp.) and bean flower thrips (Megalurothrips sjostedtii). Two separate experiments were conducted during 2009 to 2012. The first experiment targeted bean fly and bean flower thrips, comprising the treatments: seed dressings, soil drenches, foliar sprays and an untreated control. We used randomised complete block design, with four replicates. All the seed dressing and soil drenching insecticides, except Apron, significantly lowered bean fly infestation by two to 60 fold when compared with control. These insecticides, however, did not control flower thrips. Confidor® resulted in a marginal returns of 0.89 and Actara® -0.11 compared to seed dressings, which ranged from 0.47 to 1.82. The second experiment laid in a randomised complete block design involved the foliar application of Roket® under different spray regimes. Application of Roket® reduced infestation of thrips, and resulted in positive MRR in all the seasons.

“…Cotton varieties with higher densities of leaf trichomes exhibit resistance to insects (Bhat et al, 1984). Cultivation of resistant variety ensures the plant to keep free from insect infestation and exerts higher yield without pest management expenditure (Nault et al, 2004). Information on cotton insect pests associated with the commercial varieties are inadequate in Bangladesh and the relevance of the results in relation to weather conditions is unknown, however, knowledge on varietal susceptibility or resistance, and population dynamics of the pest regarding weather parameters are fundamental components in forecasting model of an integrated pest management program.…”

This study was conducted with CB1, CB3, CB5, CB8 and C12 cotton varieties to determine the role of leaf trichomes and meteorological factors on the abundances of aphid and jassid. The mean population of the pests on the tested varieties differed significantly and showed negative correlation with trichomes. The pests were most abundant on CB12, and each variety revealed significantly higher population of jassid than that of aphid. Both the pests built up their population in the juvenile stage of the plants (73 days after sowing) and continued until harvesting. Aphid population was the highest on CB12 in the first week of November, whereas maximum abundance of jassid was on CB12 in the third week of December. Weather parameters were found insignificant on aphid abundance, but jassid population on the varieties was correlated with maximum and minimum temperatures, relative humidity and rainfall. Multiple regression equation based on weather parameters exerted 8.8 -43.2% and 54.4 -77.7% role on population build up of aphid and jassid, respectively. Maximum temperature had the most important effect which contributed 61.2% population fluctuation of jassid on CB12.
