Use of biorational for the vegetable pest control in the north of Sinaloa
Abstract
In Sinaloa the vegetable and cucurbits production are important agricultural activities, so each year a high volume of chemicalinsecticides are applied to pest control that attack these crops. This paper present the main pests insects in the region, as wellas an analysis about effects of biorational insecticides on these pests. Was found that for control of Bemisia argentifolii Bellows & Perring (Hemiptera: Aleyrodidae) is used Neem oil 0.2%., for kill nymphs of Bactericera cockerelli Sulc. (Homoptera: Psyllidae) soursop Annona muricata L. (Annonales: Annonaceae) at doses of 2500-5000 mg/L., for Liriomyza trifolii Burgess (Diptera: Agromyzidae) neem seeds 2%., to Myzus persicae Sulzer (Hemiptera: Aphididae) rapeseed oil at doses 920 g/L (2% v/v)., to Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) spinosad (Conserve®) 48-60 mg/L., and for Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae) granular viruses (105 OBs/mL) combined with neem (DalNeem TM emulsifiable oil and NeemAzal TM -T/S at doses of 8 mg/L, everyone). The use of these products and the dose depends on the type of pest and crop. In general these products cause insect mortality greater than 95%, besides having low toxicity on natural enemies, so that these can be used individually or in combination in integrated pest control schemes against vegetable pests, and also for disease vectors insects in the northern of Sinaloa.
