Abstract:
Plant galls (cecidia) are pathologically produced cells, tissues, or organs of plants that have developed by hypertrophy and hyperplasia of plant tissues under the effect of gall causing organisms. Madhuca longifolia (Koenig) j.f Macb. is an economically and medicinally very important plant of the family Sapotaceae. It is a tropical mixed deciduous tree. Various galls due to insect infestation are found on almost all tree species. Leaf galls of Madhuca longifolia induced by insects of order Diptera and Hymenoptera represent a unique pattern of chemical perturbations which normally do not occur

Abstract:
Izeniola obesula Dorchin and Stefaniola defoliata Dorchin (Diptera: Cecidomyiidae: Lasiopterini) are monophagous gall midges each inducing a unique kind of gall on stems of the salt marsh plant Suaeda monoica Gmelin (Chenopodiaceae). The morphogenesis of these two types of galls was studied in relation to the life history of the midges as observed both in the field and the laboratory. Izeniola obesula larvae penetrate the pith parenchyma through the growing shoot apex, causing intensive cell proliferation and inducing differentiation of novel vascular tissues and a sclerenchyma sheath around t

Integrated Management Approach for Control of the Pest Complex of Olitorius Jute, Corchorus Olitorius L. Field trials were conducted with six treatments against the pest complex of olitorius jute var. JRO-524 during 2004 and 2005 at Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India. The results revealed that incidence of Anomis sabulifera Guen., Spilarctia obliqua Wlk., Myllocerus discolor Bohemus, Apion corchori Marshall and Polyphagotarsonemus latus Banks were found causing a minimum of 6.10, 4.68, 12.38, 5.09, and 10.47 percent plant infestation, respectively.

Abstract:
The yaupon psyllid, Gyropsylla ilecis (Ashmead), is a native insect of the family Psyllidae, order Hemiptera (Figure 1). The insect is inconspicuous during most of the year, but the leaf galls it produces in spring are more easily observed. Nymphs feed on the new growth of yaupon holly, Ilex vomitoria, causing leaves to deform into a protective gall. The yaupon holly, native to the southeastern United States, is used as an ornamental tree or shrub and has also been used for centuries to produce a caffeinated, tea-like beverage. The yaupon psyllid is considered a minor aesthetic pest due to the

Abstract:
Abstract Gall wasps (Hymenoptera: Cynipidae) have fascinated researchers for centuries due to the elaborate diversity of charismatic galls they produce, the presence of unique reproductive systems (e.g., a form of cyclical parthenogenesis), the possible convergent evolution of semiparasitic gall wasp forms (i.e., “inquilines”), and their multitrophic interactions. While many classifications for gall wasps have been proposed, recent DNA sequence efforts combined with taxonomic revisions are beginning to clarify the evolutionary relationships of this group. To date, however, a well resolved phyl

Abstract:
Temperature variation affects interactions involving plants, herbivores, and parasitoids, causing a mismatch between their phenological cycles. In the context of climate change, climatic factors can undergo profound and sudden changes, such as sudden hot or cold snaps. Herein, we show that the number of episodes of short but sustained low temperatures has increased, mainly during May, over the last two decades. We subjected galls induced by the Asian chestnut gall wasp (ACGW) Dryocosmus kuriphilus to cold stress to assess whether and, if so, how it affected the pest and its parasitoids. Over t

Abstract:
Freezing of animals is often portrayed to begin after they supercool several degrees Celsius below the melting point of body fluids. This supposition is based on laboratory protocol that usually exposes animals only to dry air during freezing episodes, whereas, in nature, animals may be in direct contact with external ice or snow at temperatures above the supercooling point of their body fluids. This raises the possibility that ice nucleation may occur across the epithelium or cuticle, causing the freezing of body fluids. We tested this possibility in two freeze-tolerant animals, the wood frog

Adelgids (Hemiptera: Adelgidae) gall vegetative and reproductive shoots of interior spruce (Picea spp.), causing growth impairment, seed loss, and aesthetic decline. We tested the theory that susceptibility to galling is under genetic control in spruce. We assessed natural galling incidence in a spruce progeny test located in southern British Columbia. The experiment was composed of a replicated 13-parent incomplete, partial diallel with 42 full-sib families. Moderate evidence of genetic control of susceptibility–resistance was observed with individual narrow-sense heritability of 0.17. We obs

Abstract:
Abstract Species of Eurytomidae are associated with many communities of phytophagous insects, many being phytophagous (gall inducers, inquilines or seed feeders) and causing different types of injury to plants, others being entomophagous, including parasitoids of a wide range of insect hosts in the orders Coleoptera, Diptera (mainly Cecidomyiidae), Hymenoptera (Aculeata) and Lepidoptera, and even some being recorded from spider (Araneae) and cicada (Hemiptera) eggs. This chapter provides a checklist for the family Eurytomidae. It provides information on species diversity, host records, distribution records by province in Iran, as well as world distribution. Comparison of the eurytomid fauna with adjacent countries indicates that the fauna of Iran (127 species) is most diverse, followed by Turkey (98 species), Russia (74 species), Kazakhstan (60 species), Turkmenistan (33 species), Iraq (11 species), Azerbaijan (10 species), Armenia (nine species), Afghanistan and United Arab Emirates (both with four species) and Pakistan and Saudi Arabia (both with two species). No species have been recorded from Bahrain, Kuwait, Oman or Qatar. However, 150 eurytomid species were reported from the former USSR, indicating that the fauna was relatively well studied, though several species were recorded without indication of exact region within this large area. Of the countries adjacent to Iran, Turkey shares the highest number of known species with Iran (58 species), followed by Kazakhstan and Russia (both with 25 species), Turkmenistan (17 species), Azerbaijan (seven species), Iraq (six species), Armenia (four species) and Afghanistan (two species).
