Fruit Crops: Plum



Pseudococcus viburni (Signoret) is reported as pest of plums in Chile (Gonzalez et al. 1996). In Porterville, Tulare County, California, Pseudococcus comstocki (Kuw.) has been reported from a total of 65 food plants, including plum (Meyerdirk and Newell 1979). The Comstock mealybug P. comstocki was also observed in the Odessa region of the Crimea (USSR) on plum (Romanchenko and Bel’skaya 1981). In Apsheronsk Peninsula, Azerbaijan SSR, USSR, Phenacoccus mespili Sign. was shown to be a pest of many fruit crops, including cherry plum. In Chile, plums were found infested with P. viburni and its associated ant, Iridomyrmex humilis (Mayr) (Curkovic et al. 1995). Dysmicoccus brevipes (Cockerell) was found in a plum orchard in Auckland, New Zealand, in November (Richmond and Cowley 1998). Rhizoecus kondonis Kuwana is a subterranean pest of plums and other crops, primarily in the Sacramento Valley of California. Significantly, more R. kondonis were found 15.2–45.7 cm deep in the soil (averaging 8.3/1240 cm3 soil core sample) compared with depths of 0–15.2 cm (averaging 2.2/sample) (Godfrey and Pickel 1998) (Fig. 31.1).Mealybugs are injurious to plum in Chile,California,Crimea,New Zealand etc. In Chile, a new approach to minimize risks is suggested through control programmes against Pseudococcus. viburni in plums starting at the post harvest season, followed in the next early spring season with the chitin inhibitor buprofezin. In California, exotic parasioids Allotropa burrelli Mues., A. convexifrons Mues. and Pseudaphycus malinus Gah. were found to be successfully established on Ps. Comstocki. In Apsheronskiy Peninsula in the Azerbaijan SSR, USSR, Phenacoccus mespili Sign was shown to be a pest of peach, apricot, quince, cherry-plum, cherry, bird-cherry, apple, pear and ash. The most important natural enemy was the encyrtid Pseudaphycus phenacocci Yasnosh which parasitized about 73.8 % of the pest population in late August and September. In the Odessa region of the Crimea (USSR), for control of the Comstock mealybug Ps. comstocki on plum, Pseudaphycus was introduced and infestation declined rapidly, parasitism being 98 %.
