Competition For Food

AbstractThe effects of sprays of DDT, azinphos-methyl, and Ryania applied to a pear orchard on population densities of insect predators of Psylla pyricola Förster were assessed. The P. pyricola in the orchard were naturally tolerant to DDT and Ryania and highly resistant to azinphos-methyl. DDT eliminated or severely reduced numbers of Deraeocoris brevis piceatus Knight, D. fasciolus Knight, Diaphnocoris provancheri (Burque), and Campylomma verbasci (Meyer). Chrysopa carnea Stephens and C. oculata Say were moderately reduced. Anthocoris antevolens (White) and A. melanocerus Reuter were highly tolerant to DDT. Azinphos-methyl severely reduced numbers of A. antevolens, A. melanocerus, C. verbasci, and D. provancheri. C. carnea and C. oculata were moderately reduced. D. brevis piceatus and D. fasciolus were tolerant to azinphos-methyl. Ryania severely reduced numbers of A. antevolens, A. melanocerus, and C. verbasci; moderately reduced D. provancheri; and did not affect D. brevis piceatus, D. fasciolus, C. carnea, or C. oculata.In the DDT-treated plots the relative densities of Anthocoris spp. approximately doubled compared with the untreated plots. This was probably due to removal of competition for food by other predator species. Large increases ill the relative densities of Deraeocoris spp. were also observed in the Ryania treatments, probably for similar reasons. Significant increases in the P. pyricola populations in response to removal of predation pressure by the insecticide treatments occurred in the DDT and azinphos-methyl plots bur not in the Ryania plots.

Predacious Species

Three mirids, Diaphnidia pellucida Uhler, Hyaliodes harti Knight, and Campylomma verbasci (Meyer), are effective predators of the red mite and probably of the clover mite from early in June until the latter part of July. These three species are the only important predacious mirids under the conditions of the present spray practices in Nova Scotia. Gilliatt (2) has given an account of the life-histories of the three specics and discussed their importance in the natural contrnl of the red mite, and his account need not be repeated here. The three mirids are often the only important predacious species in many commercial orchards during the summer months because of the destruction of I. tiliae and H. faurei by the sulphur sprays emploved around the bloom period. Their presence in such orchards is in itself evidence that neither bordeaux mixture nor flotation sulphur reduces their numbers. Observation on a considerable number of occasions showed that iron carbamate has no effect on these mirids. An opportunity to test some of the common spray chemicals on two of the species was presented in the F. Palmer orchard at Berwick in 1947. Two trees were sprayed with each of the materials listed, and the insects were collected as they dropped on two trays, of 32 square feet each, which had been placed beneath the trees.

AbstractThe mullein bug, Campylomma verbasci (Meyer), was successfully established on eggplant cv. “Black Beauty” using the twospotted spider mite, Tetranychus urticae Koch, as a source of prey for early instars. Colony-raised teneral females lived 17.4±0.8 days (mean±SE) at 25°C, and their progeny averaged 6.7±0.6 nymphs per 48-h oviposition period (range 0–36). Fecundity peaked during days 6–10 and declined steadily beyond day 16. Over their lifespans, females produced eggs that hatched into 37.5±8.2 nymphs (range 2–184). Eggs from a 24-h oviposition period required from 7.2±0.1 days at 27°C to 13.0±0.2 days at 20°C for 100% hatch. An estimated developmental threshold of 9.5°C (r2 = 0.50) was obtained using the equation: rate of development = −0.075 + 0.008 (temperature). The frequency distribution of hatch at each of four constant temperatures was unimodal and approximated a normal distribution. Nymphal development at 22°C required 2.8±0.2, 3.8±0.2, 4.0±0.3, 3.9±0.2, and 6.0±0.3 days for instars 1–5, respectively.

Two new species of Phylini, Glaucopterum alborubrum sp. nov. and Compsidolon schrenkianum sp. nov. are described from Xinjiang province of China. Illustrations of the male genitalia, tarsus and pretarsus, photographs of the dorsal habitus, known hosts, and distributional records are provided for each species. The following 13 species of Miridae are recorded for the first time from China: Anonychiella brevicornis (Reuter, 1879), Atomophora mongolica Konstantinov, 2000, Blepharidopterus angulatus (Fallén, 1807), Compsidolon eximium (Reuter, 1879), Dichrooscytus consobrinus Horváth, 1904, Dichrooscytus kerzhneri Josifov, 1974, Hallodapus montandoni Reuter, 1895, Orthotylus nassatus (Fabricius, 1787), Orthotylus (Melanotrichus) schoberiae Reuter, 1876, Phaeochiton ebulum Putshkov, 1977, Pilophorus confusus (Kirschbaum, 1856), Tuponia (Chlorotuponia) prasina (Fieber, 1864), Tuponia (Tuponia) soongorica Drapolyuk, 1980.

Feeding Techniques

AbstractSix species of predacious Miridae, common to apple trees in Nova Scotia, were used to develop laboratory rearing and feeding techniques for comparing the abilities of predators to consume prey. The test prey species was the European red mite, Panonychus ulmi (Koch), in the winter egg stage. The numbers of eggs consumed per day and per instar in the tests compared favourably with the known predatory values of these mirids under orchard conditions. Both sources of information were used to give the predators a tentative rating. The mirids Hyaliodes harti Knight, Diaphnocoris pellucida (Uhler), Pilophorus perplexus D. and S., and Blepharidopterus angulatus (Fall.) are effective predators, approximately equal to each other in ability to consume the winter eggs of the red mite. The two species Campylomma verbasci (Meyer) and Atractotomus mali (Meyer), which are phytophagous as well as predacious, were less voracious.The results indicate it may be feasible to develop a series of weighting factors, one for each stage of each predacious species, based on ability to consume prey.

AbstractIn Ontario several species of polyphagous arthropods consumed nymphs and apterous adults of the green apple aphid, Aphis pomi DeGeer, as determined by serological assays and feeding trials. The most abundant predators on apple tree foliage were the reduviid Acholla multispinosa L., the mirid Campylomma verbasci (Meyer), the coccinellids Coccinella septempunctata L. and Adalia bipunctata L., and coccinellid and chrysopid larvae. An efficacy index developed to assess the effectiveness of foliage-inhabiting predators indicated that those with the greatest potential were Chrysopa larvae and adult C. septempunctata in 1987, and adult C. septempunctata and C. verbasci in 1988. The earwig, Forficula auricularia L., showed potential as a predator of A. pomi in 1989. Of the epigeal arthropods tested, the carabids Amara aenea DeGeer, Bembidion quadrimaculatum oppositum L., and Harpalus aeneus F., and the ants Formica fusca group, Myrmica ameryana Forel, and M. monticola Wheeler were the most active feeders on A. pomi.
