“…In this study, a significantly lower number of L. lineolaris adults was observed on snap bean cultivars ‘BA0958’, ‘Barron’, ‘Bronco’, ‘Caprice’, ‘Colter’, ‘Gold Mine’, ‘Golden Rod’, ‘Greenback’, ‘Greencrop’, ‘Long Tendergreen’, ‘Maxibel’, ‘Prevail’, ‘PV-857’, and ‘Roma II’ compared to other cultivars. Host plant resistance shown by some bean cultivars against L. lineolaris was documented in previous studies [ 39 , 40 ]. For instance, snap bean cultivars ‘Bountiful’ and ‘Columbia Pinto’ supported the lowest number of L. lineolaris adults [ 39 ].…”

“…This is the first study to determine the population dynamics of multiple pests, pollinators, and natural enemies on 24 local and commercially available bush snap bean cultivars in the southern United States. Previous studies concentrated on determining the susceptibility of different snap bean cultivars to only one major pest, such as B. tabaci [ 11 , 12 , 13 , 30 ], E. fabae [ 15 , 38 ], or L. lineolaris [ 39 , 40 ]. Therefore, this study might contribute to the knowledge of the population dynamics of insect pests and beneficials as impacted by the cultivation of snap bean cultivars.…”

Snap bean is an important crop in the United States. Insecticides are commonly used against pests on snap bean, but many pests have developed resistance to the insecticides and beneficials are threatened by the insecticides. Therefore, host plant resistance is a sustainable alternative. Population dynamics of insect pests and beneficials were assessed on 24 snap bean cultivars every week for six weeks. The lowest number of sweetpotato whitefly (Bemisia tabaci) eggs was observed on cultivar ‘Jade’, and the fewest nymphs were found on cultivars ‘Gold Mine’, ‘Golden Rod’, ‘Long Tendergreen’, and ‘Royal Burgundy’. The numbers of potato leafhopper (Empoasca fabae) and tarnished plant bug (Lygus lineolaris) adults were the lowest on cultivars ‘Greencrop’ and ‘PV-857′. The highest numbers of adults were found in Week 1 (25 days following plant emergence) for B. tabaci and Mexican bean beetle (Epilachna varivestis); Week 3 for cucumber beetle, kudzu bug (Megacopta cribraria), and E. fabae; Weeks 3 and 4 for thrips; Week 4 for L. lineolaris; and Weeks 5 and 6 for bees. Temperature and relative humidity correlated with B. tabaci, E. varivestis, bee, and predator ladybird beetle populations. These results provide valuable information on the integrated pest management of snap beans.

“…In Lima beans in California, United States of America, an average of 0.7 Lygus bugs/ sweep has been recorded in stage R1-R3, with 2.9 bugs/sweep later in the season (Bushing et al 1974). In edible bean varieties in stage R1-R3 a maximum of 12.6 Lygus bugs/sweep was observed in Washington, United States of America (Hagel 1978). In Manitoba, mirid densities in field beans and soybeans tend to be lower than those observed in other Manitoba annual crops and those observed on beans in the United States of America.…”

“…The highest number of insects was in 2010, which had the lowest number of damaged seeds. Hagel (1978) also found little or no seed pitting in pinto beans, in contrast to 5–20% of pitted seeds in other types of beans that did not include navy beans. Soybeans are not preferred hosts for Lygus bugs, and peak numbers similar to those we observed cause no loss in soybeans in Mississippi (Snodgrass et al 2010), although high numbers of Lygus adults, caged on soybean buds or blooms, cause yield loss (Broersma and Luckmann 1970).…”

In Manitoba, Canada, commercial soybeans and two types of field beans, navy and pinto, were sampled for plant bugs. At the centre and margins of 36 fields, sweep net and tap tray samples were taken weekly. In all three crops, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae) comprised > 78% and Adelphocoris lineolatus (Goeze) (Hemiptera: Miridae) < 10% of adult mirids. Species composition varied among years but not among crops. For Lygus Hahn, nymphs were 46% of the catch in trays and 23% in sweeps, but total Lygus catch in trays was > 2% of that in sweeps. Catch/ sample effort was similar at field centres and margins for both Lygus adults and nymphs. Lygus lineolaris reproduced and developed in all three crops. In field beans, Lygus adults were first collected in late vegetative and early pod set stages and late instar nymphs and adults were present from pod elongation until maturityresults consistent with immigration of first summer generation reproductive adults and development of the second generation in the crops. There was evidence of late season immigration of Lygus into all crops. There was no loss of seed quantity attributable to mirids in any of the crops; in field beans there was no evidence that mirids reduced seed quality.
