effects of three quercus species on feeding performance of the green oak leaf roller, tortrix viridana l. (lepidoptera: tortricidae)
feeding performance of the green oak leaf roller, tortrix viridana (linnaeus) was determined on three host plants including quercus libani oliv, quercus infectoria oliv, and quercus branti lindl, under laboratory conditions. mean total leaf weight consumed by larvae was the highest on q. branti (0.31 g) and the lowest on q. libani (0.14 g).the feeding index was the highest on q. libani while th...
متن کاملinvestigation of nutritional indices of green oak leaf roller (tortrix viridana l.) on quercus infectoria and q. libani in oak forests of piranshahr, west azerbaijan, iran
introduction: land use change, deforestation, grazing, intentional and unintentional fire and invasive pests and diseases are all the major cause of damage to the zagros forest ecosystem. the green oak leaf roller (tortrix viridana l.) is one of the important pests of zagros forests. larvae of the pest significantly damage the oak forests with feeding on leaves and buds of different species of ...
متن کاملEffects of orchard host plants (apple and peach) on development of oriental fruit moth (Lepidoptera: Tortricidae).
Studies were designed to examine the effects of host plants (apple, Malus domestica Borkh., and peach, Prunus persica L.) on the development of oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae). Oriental fruit moth larvae developed faster on peach than on apple, both on fruit as well as on growing terminal shoots. On fruit, these differences were shown to cause signific...
متن کاملTree-insect interaction - defence response against herbivorous insects
Background The defoliation of oaks is an urgent problem for forestry in Central Europe. During the last outbreak of the green oak leaf roller(Tortrix viridana) in 2003-2005, we observed fundamental differences in the defoliation level of individual Quercus robur trees in Germany. Some of the trees seem to be somehow “tolerant” (T oaks) against the insects grub while some seem to be conspicuousl...
متن کاملeffect of different solanaceous host plants on nutritional indices of spodoptera exigua (lepidoptera: noctuidae)
the beet armyworm spodoptera exigua (hübner) is a serious and economically important pest of solanaceous crops worldwide. the nutritional indices of this pest on three host plants including pepper capsicum frutescens, eggplant solanum melongena and tomato solanum lycopersicum were determined under laboratory conditions at 26 ± 1 °c, 60 ± 5% rh and 16: 8 (l: d) h. the highest relative consumptio...
