Examining dead insects from different locations in Mazandaran, Gilan and TehranProvinces, specimens with fungal outgrowth were selected for further investigations. After isolation and purification of fungi they were identified as follows:Beauveria brongniartii (Sacc.) Petch*On Coccinella septempunctata, Tehran Prov., Varamin, Ghara-Aghaj mountains, M.H. Ghassemi (IRAN 1025 C). Paecilomyces tenu...

Dead spot is a relatively new disease of creeping bentgrass (Agrostis stolonifera L.) incited by Ophiosphaerella agrostis Dernoeden, M.P.S. Câmara N.R. O’Neill van Berkum et M.E. Palm. Limited information is available with regards to chemical and cultural management strategies for dead spot. Two field studies were designed to evaluate the influence of various fertilizers and iprodione on the re...

Entomotoxicology is based on using insect evidence recovered from a dead body to find out the cause and time of death. Drugs can accumulate in fly larvae when they ingest flesh deceased persons alter normal development causing implications calculating postmortem intervals. Lorazepam an antidepressant generally used treat anxiety. Larvae Chrysomya rufifacies were fed beef liver mixed with loraze...

Spodoptera exigua multinucleopolyhedrovirus (SeMNPV) and Spodoptera litura nucleopolyhedrovirus (SpltNPV) are genetically similar, but the larvae of S. exigua are not susceptible to SpltNPV. The aim of this study was to identify whether any process was inhibiting SpltNPV infection at some point. S. exigua larvae infected with a high concentration of wild-type SpltNPV by oral inoculation produce...

Curculio glandium is one of the pre-dispersal seed predators occurring in Central Europe. It associated with Quercus robur, acorns which are shelter and food sources for developing larvae. Females species, to our knowledge, lacking marking pheromones or do not use them; therefore, nature, multiple infestations (over 10 eggs larvae) same host fruit can be found. Such density provoke very strong ...

Chrysomya megacephala (F) is a blow fly species of medical importance, being pestiferous and a mechanical carrier of various microorganisms to human food. Various strategies to reduce the fly population in endemic areas are needed. We investigated the effects of microwaves at 2,450 MHz, with third-instar exposure times of 7, 10, 15, 30 and 60 seconds on the larvae. Survival of the larvae was mo...

To study the effects of heavy-ion radiosurgery on the hemopoietic function of a silkworm, hemopoietic organs of larvae were locally irradiated with carbon-ion beams, and the changes in the hemocyte density and in the hemocyte function were investigated. When the larvae were irradiated by 50 Gy to 300 Gy carbon ions on the 3rd day of the 4th instar, the hemocyte densities did not change for a wh...

Whereas long-term storage of liquid food in the crops of worker ants and storage of dry seeds are well-known, widespread, and sometimes spectacular phenomena, there have been no previous reports documenting the storage of dead insect prey. Predacious ants typically devour their insect prey within a short time. Given a bonanza of insect prey, the fire ant, Solenopsis invicta, desiccates small pi...

Transgenic poplar lines 'Shanxin' (Populus davidiana×Populus bolleana) were generated via Agrobacterium-mediated transformation. The transgenic lines carried the expression cassettes of Cry1Ac + SCK, Cry1Ah3, and Cry9Aa3, respectively. The expression levels of the exogenous insect resistance genes in the transgenic lines were determined by Q-PCR and Western blot. Leaves of the transgenic lines ...
