The Tomato Leaf Miner (TLM), Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a cosmopolitan tomato pest that has driven a renewed reliance on pesticides in tomato production, negatively affecting biological control of other pests and creating environmental and health hazards. We tested five locally important Iranian tomato cultivars (TD, Kar...

The aim of this study was to investigate the host stage preference and functional response of Diaeretiella rapae (Hymenoptera: Braconidae) reared on Schizaphis graminum (Hemiptera: Aphididae). Firstly, host stage preference was determined under choice and no-choice tests. The parasitoid showed a preference for second instar nymphs of S. graminum in...

The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is one of the most important and destructive pests of citrus in the world, because of its ability to vector bacteria Candidatus Liberibacter americanus, and Candidatus Liberibacter asiaticus the presumed causal pathogen of huanglongbing (HLB) or greening disease. The biolog...

For effective integrated pest management (IPM) programs, it is essential to determine the thermal requirements and apply an accurate forecasting method based on daily degree units of pests. The present study investigated the physiological time (Degree-Days) and the number of generations of tomato leaf miner (TLM), Tuta absoluta (Meyrick) in Varamin...

Tomato leaf miner (TLM), Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most destructive tomato pests worldwide. We tested quantity and quality of tomato fruits after simultaneous use of two biological control agents, the predatory mirid bug Nesidiocoris tenuis (Reuter) and the egg parasitoid Trichogramma brassicae Bezdenko agains...

Tomato leaf miner (TLM), Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a serious pest of tomato production in many parts of the world. The TLM has demonstrated capacity to evolve resistance to insecticides, and residues of these on tomato fruit pose hazards to human health, making biological control solutions an urgent priority. We assessed...

Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae), a common zoophytophagus bug, is a biological control agent for several groups of noxious agricultural pests, including whiteflies, aphids, and leafminers. To improve mass-rearing of this species and to optimize its application in integrated pest management, nymphal survival and developmental times...

Greenhouse products are subject to contamination by pesticides used to control pests and diseases. Toxicity on human and non-target animals, destruction of environment, and bioaccumulation are just some of the problems caused by indiscriminate use of pesticides. Imidacloprid and abamectin are two widely used pesticides to control greenhouse pests i...

Among environmental factors, temperature has a direct and crucial influence on the key life processes of survival, development, reproduction, and movement of poikilothermic animals and hence their population dynamics. The lower and upper temperature thresholds and optimal temperature have ramifications for all major life processes, where within a s...

Habrobracon hebetor (Say) is a parasitoid of various Lepidoptera including Helicoverpa armigera (Hübner), a key pest of different crops and vegetables. The development of both H. armigera and H. hebetor were simultaneously evaluated against a wide range of constant temperatures (10, 15, 17.5, 20, 25, 27.5, 30, 35, 37.5 and 40 °C). Helicoverpa armig...

Coccinellids are the most important predators which have been used in biological control. Cheilomenes sexmaculata Fabricius (Col.: Coccinellidae) ladybird is one of the important factors in the east of Asia that actives on the different species of aphids and psyllids as a polyphagous predator. In current study, effect of 20, 24, 28 and 32 °C temper...

Studies of prey suitability are needed to develop efficient mass rearing programs for generalist predators and to understand their potential contribution to integrated pest management. A laboratory study was conducted to evaluate the development and reproductive success of two predatory coccinellids, Oenopia conglobata (L.) and Cheilomenes sexmacul...

Components of male seminal fluids are known to stimulate fecundity and fertility in females of numerous insect species and paternal effects on offspring phenotype are also known, but no studies have yet demonstrated links between male effects on female reproduction and those on progeny phenotype. In separate laboratory experiments employing 10-day-...
