Chemical Control of Whitefly and Aphid Insect Pest of French Bean (Phaseolus vulgaris L.)
An experiment was conducted at Sher-e-Bangla Agricultural University farm to study the efficacy of some insecticides against major insect pests of French bean (Phaseolus vulgaris L.). The treatments of the experiment were T . Results showed that the lowest number of whitefly plant -1 (3.28 at 60 DAS) and aphid plant -1 (4.82 at 60 DAS), the lowest infestation intensity by whitefly (5.92%) and aphid (14.25%), the lowest infested bean yield plant -1 (52.80 at 60 DAS), highest healthy bean yield plant -1 (166.40 g at 60 DAS), highest total healthy yield (11.28 t ha -1 ), lowest total infested yield (0.64 t ha -1 ) and highest gross return (Tk. 232000.00 ha -1 ) were obtained from the use of Chlorpyriphos. The highest percent reduction of whitefly plant -1 (81.44 % at 60 DAS) and aphid plant -1 (80.15 % at 60 DAS), highest percent reduction of infested bean yield plant -1 (81.82 % at 60 DAS) and highest increase of healthy bean yield plant -1 over control (215.20 % at 60 DAS) were achieved from the same treatment. Hence Chlorpyriphos 20EC performed best to suppress the whitefly and aphid of French bean followed by Fortap 50SP.

An approach to eatablish IPM program for some sucking pests infesting garden beans plants was carried out in two successive seasons of 2004 and 2005 under field conditions in Alexandria, Egypt. The sucking pests included the aphid, Aphis craccivora Koch (Homoptera: Aphididae), the white fly, Bemisia tabaci Genn. (Homoptera: Aleyroidae) and the spider mite, Tetranychus urticae Koch Pymetrozine, thiamethoxam, carbosulfan, abamectin, azadirachtin and the detergent (Masrol 410) were tested for their efficacy in this study. Thiamethoxam, carbosulfan, and pymetrozine proved to be highly effective against Aphis craccivora Koch, while abamectin, azadirachtin, and the detergent (Masrol 410) provided a moderate effect. Moreover, thiamethoxam, pymetrozine, and abamectin showed remarkable efficacy against adults and immature stages of the whitefly, Bemisia tabaci. However, azadirachtin provided a moderate effect, while carbosulfan and detergent (Masrol 410) had no effect altogether on whiteflie...
Biology
Common bean (Phaseolus vulgaris) production and storage are limited by numerous constraints. Insect pests are often the most destructive. However, resource-constrained smallholders in sub-Saharan Africa (SSA) often do little to manage pests. Where farmers do use a control strategy, it typically relies on chemical pesticides, which have adverse effects on the wildlife, crop pollinators, natural enemies, mammals, and the development of resistance by pests. Nature-based solutions —in particular, using biological control agents with sustainable approaches that include biopesticides, resistant varieties, and cultural tools—are alternatives to chemical control. However, significant barriers to their adoption in SSA include a lack of field data and knowledge on the natural enemies of pests, safety, efficacy, the spectrum of activities, the availability and costs of biopesticides, the lack of sources of resistance for different cultivars, and spatial and temporal inconsistencies for cultura...

This study was conducted to evaluate the efficacy of some insecticides and biopesticides against aphid Aphis craccivora (Koch), leafhopper Empoasca fabae (Harris) and whitefly Bemisia tabaci (Genn.) on Indian bean during kharif, 2019 at the SKN College of Agriculture, Jobner, Jaipur. On the basis of reduction in incidence, spiromesifen 22.9SC, diafenthiuron 50WP and standard check (alternate spray of dimethoate 30EC and malathion 50 EC) were observed to be the most effective. The pyriproxyfen 10.8EC, emamectin benzoate 5SG, chlorfenapyr 10SC and spinosad 45SC were moderately effective; whereas, the Beauveria bassiana 1.15WP, Metarhizium anisopliae 1.15WP, azadirachtin 0.03EC and NSKE (5.0%) were the least effective. The maximum pod yield of 91.25 q/ ha was obtained with spiromesifen 22.9SC at par with that of diafenthiuron 50WP (88.32 q/ ha). The maximum benefit cost ratio of 57.96 was obtained with the standard check followed by pyriproxyfen 10.8EC (36.86) and emamectin benzoate 5S...

g/l. Similarly, the least per cent pod damage was observed in Chlorantraniliprole 18.5 SC treatment (12.57 %) followed by Emamectin benzoate 5 SG (15.83 %) and Spinosad 45 SC (17.60 %) which were statistically on par with each other. The results on the cost economics of pod borer complex management revealed that, among the treatments the pod yield was maximum (27.45 q/ha) in Chlorantraniliprole 18.5 SC followed by Spinosad 45 SC (25.48 q/ha) and Emamectin benzoate 5 SG (24.80 q/ha) which were statistically on par with each other. Accordingly, the highest net profit (Rs.63969 /ha) was documented in chlorantraniliprole 18.5 SC. This was followed by spinosad 45 SC (Rs.58019 /ha), emamectin benzoate 5 SG (Rs.56807/ha). The highest cost benefit ratio was obtained in chlorantraniliprole 18.5 SC (1: 3.48). This was followed by emamectin benzoate 5 SG (1: 3.23), spinosad 45 SC (1: 3.15).
Efficacy of IPM Modules Against Major Insect Pests of Common Bean Phaseolus vulgaris
Indian Journal of Entomology
This experiment evaluated some IPM modules against pests of common bean Phaseolus vulgaris, and observed that the module with soil application of carbofuran 3G @ 32.5 kg/ ha+1st of spray with dimethoate 30EC @ 0.03% (45 days after sowing- DAS) and 2nd with dichlorvos 76SC @ 0.076% (70 DAS) was the most effective. This resulted in maximum reduction of pests (76.85, 75.43, 69.97% of aphid, whitefly and weevil, respectively) and resulted in maximum gross returns (`₹94,068), net returns (``₹64,017) and benefit cost ratio (2.13). Besides, these effect of intercropping of beans with maize revealed a reduced population density of all the major pests, as compared to sole bean crop.
A field experiment was carried out during the two successive growing seasons of 2004 and 2005 at the experimental Station of National Research Centre to investigate the impact of organic fertilization with composted egg-plant, green pepper, maize and okra plant residues on bean infestation with white fly, leaf miners, aphids and red spiders as well as certain growth parameters and snap bean yield in comparison with the traditional recommended treatments. The obtained results show that the composted green pepper residue positively affects the reduction percent of infestation with the various tested blights. The reduction percent ranged from 15.8 for white fly to 76.1 for red spiders; meanwhile the reduction percent reached 22.9 and 53.2 for leaf miners and aphids consecutively. Organic fertilization with the composted residue of okra or farmyard manure reduced infestation numbers with three out of the four tested blights viz. white fly, leaf miners and red spiders for composted okra residue and leaf miners, aphids and red spiders for farmyard manure. The reduction percent reached 29.6, 65.7 and 21.9 by turns for the composted okra residue and 55.0, 27.3 and 61.9 respectively for farmyard manure treatment. Leaf miners were the only blight that affected by organic manuring with the composted egg-plant residue where the reduction percent amounted 33.6, while chicken manure application positively affect reduction percent of infestation with each of white fly and leaf miners as the reduction percent reached 57.8 and 74.0 respectively. The positive control affect the infestation numbers of leaf miners, aphids and red spiders with reduction percent reached 60.0, 36.7 and 67.7 by turns. Comparable results to the positive control were obtained for the tested bean growth parameters owing to the organic manuring of bean plants with the diverse composted agricultural residues without significant variations. Organic manuring of bean plants with different types of composted agricultural residues induced yield of snap bean significantly overcame the positive control either alone or when accompanied with microelements.
