Evaluation of companion crops for thrips (Thysanoptera: Thripidae) management on French bean Phaseolus vulgaris (Fabaceae)

Evaluation of a Push-Pull Strategy for the Management ofFrankliniella bispinosa(Thysanoptera: Thripidae) in Bell Peppers

“…Numerous studies showed that various host plants of Orius, including H. annuus, when used as companion plants resulted in reduced thrips in the main crop (Bottenberg et al 1999, Kasina et al 2006, Ló pez and Shepard 2007, Frantz and Mellinger 2009, Nyasani et al 2012. Coll (1998) in reviewing the scientiÞc literature found that plant diversiÞcation increased Orius species in eight studies, numbers were the same in 11 studies, and numbers were decreased in one study.…”

“…Numerous studies have shown that companion plant species that are hosts for Orius species resulted in reduced numbers of Frankliniella species thrips in the main crop. Kasina et al (2006) and Ló pez and Shepard (2007) reported that companion plantings of Tagetes erecta L., Daucus carota L., Coriandrum sativum L., Brassica oleracea L., C. annuum, Zea mays L., and Tanacetum parthenium (L.) Schultz-Bipontinus reduced the numbers of Frankliniella occidentalis Pergande on main crops of Phaseolus vulgaris L. and on species of medicinal plants. Nyasani et al (2012) reported that intercrops of Solanum tuberosum L. and Helianthus annuus L. reduced populations of F. occidentalis and increased populations of Orius spp.…”

Evaluation of Pest Management Strategies against Sucking Insect-Pests for the Safety of Beneficial Insects in Vegetable French bean (Phaseolus vulgaris L.)

“…Economic significance of the French bean crops compelled the vegetable growers to use more frequent insecticide applications of recommended and non-recommended chemicals for suppressing the insect pest population which led to the elimination of beneficial insects. In agronomic systems, beneficial insects especially parasitoids, predators and pollinators contribute to enhance the ecological stability of the cropping system and thereby increasing the crop yield (Nuessly et al, 2004;Landis et al, 2005;Kasina et al, 2006). In recent years, pest management strategies receiving greater attention of the pest management workers throughout the world for their utilization as eco-friendly and sustainable and hence there is a need to develop Integrated Pest Management modules for the safer and healthier production of vegetable crops.…”

Frankliniella occidentalis (Pergande) integrated pest management programs for fruiting vegetables in Florida

“…Various plant species offer habitat for important natural enemies of thrips and other insects 50. Numerous plant species have been shown to attract enough natural enemies to manage western flower thrips populations 51, 52. In Florida, Bidens alba , sunflowers, Wedelia trilobata and two species of clover are hosts for minute pirate bugs and other natural enemies,53 and plantings near crops of fruiting vegetables increase biological control of thrips 8.…”
