The southern green stink bug Nezara viridula (Linnaeus) is a polyphagous species that causes economic damages to many crops in Bulgaria. aim of this study was identify the parasitoid could suppress populations viridula. A lot agricultural were inspected region Plovdiv, Bulgaria, for presence egg parasitoids and imaginal pest. Egg masses adults collected during field surveys 2019-2021 Southern o...

Maize is one of the most important cereal crops and called ‘the queen cereals’ because its high yielding potential than other cereals. Fall armyworm, Spodoptera frugiperda serious invasive pests found to cause higher yield loss extensive damage on maize. Considering ecological environmental consequences, biological control insect gaining importance as an alternative insecticides. However, succe...

Parasitoids are important insects that commonly released into the environment to reduce population sizes of pest species. The lifetime reproductive success parasitoids mainly depends on host availability and mature eggs. Consequently, it is predicted female wasps must balance risk egg or (time) limitation with maximized fecundity. Typically, synovigenic females, which continue eggs throughout t...

Effect of host-larval diet on the host acceptance and suitability egg parasitoid Telenomus remus Nixon (Hymenoptera: Scelionidae) Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae). The life history parasitoids is an important factor that can determine their ability to attack a host. type food consumed by affect such as searching behavior, acceptance. In this research, we evaluate effec...

Augmentative releases of parasitoid wasps are often used successfully for biological control of fruit flies in programs worldwide. The development of cheaper and more effective augmentative releases of the parasitoid wasp Diachasmimorpha tryoni (Cameron) (Hymenoptera: Braconidae) may allow its use to be expanded to cover Queensland fruit fly, Bactrocera tryoni (Froggatt) (Diptera: Tephritidae),...

Ongoing intensification of rice production systems in Southeast Asia is causing devastating yield losses each year due to rice hoppers. Their continuing development of immunity to resistant rice varieties and pesticide applications further complicates this problem. Hence, there is a high demand for biological control agents of rice hoppers. Egg parasitoid wasps are among the most important natu...

The functional response of two egg parasitoids, Gonatocerus tuberculifemur (Ogloblin) and G. ashmeadi Girault (Hymenoptera: Mymaridae), to varying densities of Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae) eggs was studied in the laboratory. G. tuberculifemur showed a type II functional response where parasitism increased at a decreasing rate as host egg density increased from 5 to...

Greencover crops are widely recommended to provide predators and parasitoids with floral resources for improved pest control. We studied parasitism and predation of European grapevine moth (Lobesia botrana) eggs and pupae as well as predatory mite abundances in an experimental vineyard with either one or two sowings of greencover crops compared to spontaneous vegetation. The co-occurrence betwe...

Surveys for egg-parasitoid wasps were conducted in Rafsanjan, Iran, on two species of Pentatomidae (Hemiptera) found pistachio orchards, Acrosternum arabicum Wagner and Brachynema signatum Jakovlev. Five Scelionidae (Platygastroidea) recovered, including one that is here described as new: Psix saccharicola (Mani), Trissolcus colemani (Crawford), T. darreh Talamas sp. nov. , perepelovi (Kozlov),...

Cleruchoides noackae Lin and Huber (Hymenoptera: Mymaridae) is a solitary egg parasitoid of Thaumastocoris peregrinus Carpintero and Dellapé (Hemiptera: Thaumastocoridae). The parasitoid was first described in 2009 and its biology and rearing are poorly understood. A key obstacle to the use of C. noackae as a biological control agent has been the ability to consistently rear it under quarantine...
