“…Pseudaulacaspis pentagona is among the most damaging armored scale pests of ornamental and fruit trees throughout its nearly cosmopolitan distribution (North and South America, Europe, Africa, Asia, and Australia) (Gossard 1902, Howard 1912, Simmonds 1958, Bennett and Hughes 1959, VanDuyn 1967, Beardsley and Gonzalez 1975, DeBach and Rosen 1976, Johnson and Lyon 1988, Miller and Davidson 1990. P. pentagona, a native of China, was first recorded in the United States in Florida in the early 1900s (Gossard 1902) and is currently distributed from Florida west to Texas and north to Maryland and Tennessee (Davidson et al 1983).…”

We investigated adaptation of the armored scale insect Pseudaulacaspis pentagona (Targioni—Tozzetti) to individual mulberry trees (Morus alba L.) in Maryland, USA. We tested local adaptation by transferring eggs within and between trees and by measuring the subsequent survival of developing scales. Survival of P. pentagona was significantly higher when raised on their natal host tree compared to rearings on novel trees. This finding is consistent with local adaptation of scale populations to individual host trees. However, we found evidence for differences in local adaptation of scale populations only between populations on distantly separated mulberry trees. There was no evidence for genetic differentiation of scale populations on neighboring trees, suggesting that gene flow inhibited local adaptation. By adapting to individual plants, few populations of herbivores appear to sacrifice their ability to colonize new conspecific hosts. While local adaptation may fine tune herbivore populations to individual host phenotypes, it is unlikely to play a general role in explaining the patchy distribution of herbivorous insects on their hosts plants.

“…The larvae of Pyroderces may feed on dead plant material and live and dead insects (Common ). In Florida, Pyroderces rileyi (Walsingham) has been recorded as both a scavenger of dead plant material (Hughes ) and as a predator of diaspidids (van Duyn and Murphey ). During the present survey, adult Pyroderces emerged from mature or nearly mature P. persicae covered grapevine material collected from vineyards in WA, NSW and Qld.…”

Background and Aims There is increasing interest in using natural enemies to control pests in viticulture, but in Australian vineyards, this is often hampered by a lack of information on enemies of particular pest groups. Here we provide an assessment for the first time of the natural enemies of coccids of grapevines. Methods and Results The main coccid pest, Parthenolecanium persicae, was attacked by the parasitoid Metaphycus maculipennis, which constituted 75% of the parasitoids collected from this species. The second most abundant coccid in Australia vineyards, Parthenolecanium pruinosum, was attacked only by one parasitoid, Coccophagus lycimnia. The most common coccinellid predator was Rhyzobius pulchellus, whereas other coccinellids including Cryptolaemus montrouzieri were less common. Several other coleopteran species as well as the moth Mataeomera dubia and several neuroptera are also likely to be important coccid predators. Conclusions These results point to a complex and much wider range of natural enemies attacking vineyard Coccidae than previously appreciated, although P. pruinosum may have few enemies. Significance of the Study Grapevine scale pests have an array of natural enemies including parasitoids, beetles, moth larvae and lacewings, highlighting the importance of maintaining a diverse insect community in vineyards for biological control.

“…Howard (1989) showed that mineral oil alone cannot control the P. citri but that in combination with dimethoate and chlorpyrifos, can increase the toxicity of the two toxins. Ethion, parathion, demeton-s-methyl (Meta-Systox r ), dimethoate, endosulfan (Thiodan R ) and dieldrin, plus mineral oil, was tested with ethion and parathion being the most effective combination with a mineral oil against P. citri (Duyn and Murphey, 1971). High mortality was obtained after 72 h post-treatment in the first experiment but in the second experiment (with the synergist), the high mortality were obtained after 48 h post-treatment.…”

“…Draga (2005) showed that the combination of mineral oil with the insecticides parathion, methidathion, fenoxycarb and imidacloprid can increase the toxicity on CM. Duyn and Murphey (1971) used a combination of mineral oil with some toxins (that is, etion, parathion, dimethoate, endosulfan and dieldrin) and concluded that ethion and parathion were most effective in controlling…”

Planococcus citri (Risso) (Homoptera: Pseudococcidae), is one of the key pests of citrus. The use of chemical pesticides for a long time can cause many problems such as pesticide resistance, as well as having an adverse effect on the environment. The use of chemical pesticides needs to be replaced with non-chemical control methods. The effects of tondexir (pepper extract) and palizin (eucalyptus extract) using five doses (500, 1000, 1500, 2000 and 3000 ppm) and sirinol (garlic extract) with five doses (1000, 1500, 2000, 2500 and 3500 ppm) on citrus mealybug was investigated. The effect of barter (a botanical synergist) using a single dose (1000 ppm) being added to tondexir and palizin at three doses (500, 1000 and 1500 ppm) and barter (1000 ppm) added to sirinol at four doses (1000, 1500, 2000 and 2500) on citrus mealybug was examined. Mortality was recorded after 24, 48, 72 and 96 h post-treatments. Analysis of variance showed that the highest mortality with 3000 ppm doses of tondexir and palizin was 90/60 ± 2/93 and 89/16 ± 1/92% with sirinol (3500 ppm) with 87.11 ± 1.11% mortality, respectively. However, the highest mortality by using barter plus tondexir and palizin (1500 ppm) was 94.44 ± 2.59 and 86.66 ± 3.6% and barter plus sirinol (2500 ppm) was 83.33 ± 3.6% mortality, respectively. There were significant differences between the two experiments (p < 1%).
