Abstract
Efficacy of three mineral oils, KZ 95% EC, Super Masrona 94% EC and Super Royal 95% EC against immature stages of white fly, Bemisia tabaci Thnps tabaci, Aphis spp. and Lirìomyza bryoniae were investigated on two tomato cultivars (Super strainB & Uc-97) at Sabaheia Experimental region during summer season of 2002. The obtained results revealed that Liriomyza bryoniae was the most dominant insect-pest on tomato plants of both tested cultivars. Concerning the effect of tomato cultivars on the rate of infestation, UC-97cultivar was more susceptible to infestation by the white fly, the aphid, and leaf miner than Super strain-B cultivar. The tolerant super strain-B cultivar showed the least infestation rates with all studied insects, except for thrips infestation. There were significant differences between both cultivars. Also,data also showed that míneral oil-KZ was the highest effect against white fly, leaf-miners and aphids on Super strain-B cultivar,while the mineral oil-Super royal was the highest effect against white fly and liriomyzid on UC-97 cultivar. On the contrary, the mineral oil-Super Royal gave the highest effect against the onion thrips on tomato cultivar-Super strain-B.Both mineral oils Super Royal & KZ gave closely highest effect against onion thrips on tomato cultivar UC-97. Also, it found that there was a strong positive and/or negative correlation relationship between the estimated levels of white fly and leaf miner infestations (+0.6298 and — 0.6999) after the 1 and 2 sprays of KZ mineral oil, respectively on tomato cultivar Super Strain-B. While, there was strong posìtive correlation relationship (+ 0.5892 and + 0.8956) was detected between the measured rates of white fly and leaf miner infestation after the 1st and 2nd sprays of Super Masrona oil as well as the correlated rates of leaf miner and thrips infestations (+ 0.8215 and + 0.9998) after the I and 2nd sprays of KZ oil on tomato cultivar UC-97.
