“…The X 100 = 1- effectiveness of acetamiprid + fipronil against BPH and GLH in paddy has been reported by Roshan et al (2018), hence confirm the present findings in this respect. Similar results regarding the efficacy of thiamethoxam 25 WG @0.005% obtained in the present investigation also corroborating with the earlier findings of Ganapathy and Kuruppiah (2004), Ahirwar et al (2016), Sujatha and Bharpoda (2017) against whitefly in various crops.…”

A field experiment was conducted to determine the efficacy of different insecticides against sucking pests viz., thrips, Caliothrips indicus Bangall and whitefly Bemisia tabaci Gennadius, infesting blackgram in North coastal Andhrapradesh at Agricultural College, Naira during rabi 2017-2018.The experimental results revealed that all the treatments showed significant differences in reducing the population of sucking pests over untreated check. Among the tested insecticides, thiacloprid 21.7 SC @ 0.0325% was found to be highly effective against thrips by reducing74.80 per cent thrips population followed by acetamiprid 4 % + fipronil 4% @ 2ml l-1 with 70.81 per cent over untreated control, whereas flonicamid 50 WG @ 0.0325% was very effective against the population of whitefly byreducing 72.19 per cent and lowest per cent disease incidence (17.66%) followed by acetamiprid 4% + fipronil 4% @ 2ml l-1 (64.94%) and thiamethoxam 25 WG @ 0.005% (62.21%) which were on par with each other over control.

“…The results of this study clearly indicate that insect infestations during flowering and pod formation are factors that limit the production of sufficient cowpea in the production area. This observation is in agreement with Sujatha and Bharpoda [33] which showed that cowpea is more vulnerable to insects during the reproductive stage than at the vegetative stage. Application of insecticide treatments at these stages effectively controls M. vitrata R. dentipes and A. varium infestation and ensures optimum pod yield.…”

Cowpea is one of the most important grain legumes growing in Lomami province, DR Congo. Despite the high potential for production in this region, insect pests are the main problems of cowpea producers. They most often belong to the following categories: pod borers (Maruca vitrata), pod-sucking bug (PSB) complex of which Riptortus dentipes and Apium varium. A study was conducted to evaluate the efficacy of three spray regimes of Cypermethrin on the density of M. vitrata, A. varium and R. dentipes and the performance of yield components of cowpea. Trials were conducted at three different sites, one controlled (INERA) and two peasant sites (Mpiana and Yamba). Three genetically improved varieties called Mujilanga, CNGKASC2-1-1-T, and CNGKASA7-2-M of cowpea were used. The tests were conducted using a split-plot device with three repetitions. Results demonstrate that Cypermethrin is effective against insect pests of cowpea, the population of all target pest were found to decrease in the plot treated to the untreated plot. Application of insecticide three times recorded the highest increased grain yield between 93 and 169 %. The average yield for spray regime recorded 689.1 kg, 651.8 kg and 553.3 kg for D1, D2 and D3 sprays. Famers can use two or three spray regimes of Cypermethrin to manage the pest, this option may reduce the cost, in order to achieve a sustainable level of agricultural and a high level of environmental and human health protection in cowpea field in DR Congo. Contribution/Originality:This study is one of the very few studies which have investigated the chemical spraying regime to a cowpea insect pest in the field in the central part of DR Congo. The results finding that insect pest were below the economic threshold and grain yield is highly significant with the tree or two sprayings of Cypermethrin.

“…revealed that thiamethoxam (0.025%) proved to be effective in reducing the leafhopper, whitefly and aphid population by 81.32 %, 87.78 % and 92.61 %, respectively over untreated control in cluster bean. Sujatha and Bharpoda (2017) conducted an experiment and reported that thiamethoxam 25WG (0.01%) was found to be more effective against the sucking pests by recording lowest population of 0.38 aphids and 0.08whiteflies per three leaves, respectively on greengram.…”

Grain legumes are the important source of dietary protein in tropical regions and insect pests are the major biotic constraints in the production of the grain legumes throughout the country. About 150 species of insects are known to attack pulse crops in India. Among the insect pests, the sucking pests like aphid, Aphis craccivora Koch; jassid, Empoasca kerri Pruthi; whitefly, Bemisia tabaci Gennadius, thrips,Thrips palmi Karny and flower thrips, Megalurothrips usitatus Bagnall are known to cause significant damage to the pulse crops and also indirectly acting as a vectors in transmitting the deadly diseases resulting in severe loss in grain yields of the legume crops. The present review highlights the losses caused by the sucking pests and critically review the literature generated on the bio efficacy of conventional and novel groups of chemical insecticides for the management of sucking pests infesting grain legumes at different locations in India.
