| الوصف: | The Miridae, or plant bugs, associated with noble fir, Abies procera Rehd., are discussed. Thirty six species of the Miridae were collected from noble fir. Twenty five of these species are considered only "visitors" to noble fir. The study does not deal with these species. Noble fir is a host of the eleven other species: Deraeocoris incertus Knight, Deraeocoris piceicola Knight, Dichrooscytus sp. A, Orthotylus sp. A, Paradacerla formicina (Parshley), Phytocoris neglectus Knight, Phytocoris sp. A, Pinalitus solivagus (Van Duzee), Plagiognathus sp. A and Psallus spp. A and B. Fifth instar larvae and the adults of these eleven species were examined and described. The plant bugs were collected from the noble fir foliage every seven to fourteen days from early May to mid-October, 1979 from Marys Peak in the Oregon Coast Range and the H.J. Andrews Experimental Forest in the Oregon Cascade Mountains. Distributional data were added from collecting trips in Oregon on Grass Mountain and around Mt. Hood and in Washington state at White Pass and Stevens Pass. The larvae and adults of the eleven noble fir mirid species were observed in a growth chamber. Feeding observations were recorded for eight species. The larvae and adults were examined for external signs of insect parasitism. Sticky traps placed on the boles of noble fir trees on Marys Peak collected very few mirids, suggesting that the mirids remain on the foliage and branches. Collections were made from three noble fir stands of increasing age in the Andrews Forest. All mirid species associated with the fir were present once the stand was 15-18 years old. The degree of host specificity is discussed for the eleven species. Eight species were collected regularly on noble fir from Marys Peak and ten from the Andrews Forest. Mirids were more abundant on Marys Peak than in the Andrews Forest. Possible causal factors are discussed. The periods of occurrence of the larvae and adults of the eleven species are graphed. The larvae and adults of five mirid species appeared ... |
