Merr) which is found in many soybean–growing regions throughout the world. Applying of resistant sources is one of the efficient measures to manage this nematode. In this study, reaction of 63 soybean lines to the soybean cyst nematode were evaluated in field and growth chamber conditions. Host resistance was determined on the basis of female index (i.e., number of female developed on the tested lines / number of female on the standard susceptible cultivar Lee 74 as percentage). The results demonstrated that five lines were defined as resistant, whereas 14 lines with FI 10 to 29 were considered as moderate resistance. Subsequently, 22 lines were demonstrated as moderately susceptible and 22 lines were characterized as susceptible lines. The lines which showed resistance and moderate resistance in field conditions were selected for assay under control conditions. The results of pot experiments conducted under control conditions verified the field findings.

In this research, natural enemies diversity of T. absoluta and proportion of predators or parasitoids density to moth eggs or larvae density on five tomato cultivars including Super Strain B, Super Chief, Mobil, Korral, and Early Urbana Y were studied in an experimental field during 2014 and 2015. In this study, ten predator species, four larval parasitoid species and one egg parasitoid species were collected and identified. Amongst the natural enemies, the predatory bugs Miridae and larval parasitoids Braconidae had the highest relative abundance. The Shannon diversity index for the complex of natural enemies was not significant among the five tested cultivars. The values of Morisita–Horn index for the complex of natural enemies among the five cultivars were calculated from 0.932 to 0.994. In two years, the greatest proportion of predarors density to moth eggs and larvae density (5.09% in 2014 and 6.44% in 2015), the highest proportion of larval parasitoids density to moth larvae density (3.92% in 2014 and 3.75% in 2015), and the greatest egg parasitoid density to moth eggs density (1.67% in both studied years) were recorded on Early Urbana Y. Therefore, it can be concluded that the cultivation of Early Urbana Y with increasing of the proportion of predators or parasitoids density to T. absoluta eggs and larvae density could be useful in the integrated management programs of the tomato leafminer in tomato fields.

This experiment was conducted to investigate the possible inhibitory effect of some selective paddy herbicides residues to second cropping. Experimental factors were included common paddy herbicides (thiobencarb, butachlor, oxadiargyl, bensulfuronmethyl, and non- herbicide control) and test plants (lettuce (Lactuca sativa L.) and cress (Lepidium sativum L.)). At first, herbicides were applied in paddy field and bioassay was carried out by using the soils of plots treated with those herbicides and test plants. Results showed that, in general, residual effect of paddy herbicides on the growth of second crops was different depending on plant type and herbicide. Compared with aerial parts, roots of the plants tested were more sensitive to residual herbicides. Butachlor showed the least (≤9%) and oxadiargyl the most (≥60%) inhibition on test plants, and bensulfuronmethyl and thiobencarb also had statistically similar inhibitory effect on the roots of the test plants.

Dual culture and extracellular metabolites tests were used in in vitro assays. The bacterial strains inhibited growth of P. drechsleri, the highest inhibition zones was belonged to T17-4 strain with 61.904% in dual culture and VUPF760 strain with 57.87% in cell free metabolites tests. The highest and lowest reduction rates of disease severity were belonged to VUPF760 and VUPF506 with 68.75 and 16.66%, respectively. In the second section of the study, the ability of bacterial strains to induce peroxidase, polyphenol oxidase, phenylalanine ammonia lyase and phenolic compounds in pistachio seedling was investigated 3, 6, 12 and 24 days after inoculation. Bacterial strains increased enzyme activities that reached the maximum levels 6 days after inoculation with pathogen. The highest level of phenolic compounds was observed at 6 days after pathogen inoculation in treatments of bacterial strains and Ph. drechsleri compared with control. Induction of resistance in plants even 24 days after post-treatment with bacterial strains was effective for induction of more durable resistance compared to other activators of plant defense system. The ability of bacterial strains to increase enzymes activities and levels of phenolic compounds may be some of the mechanisms responsible for their biocontrol activities.

Today using insecticides and formulations that have durable toxicity on overwintered adults is more approved, because this strategy can reduce treated area against new generation. This research was conducted with six treatments and four replications in randomized complete block design against overwintered adults of sunn pest in Qazvin (Ismail Abad Agricultural Research Station) at 2007-2008. Emulsions and micro capsules formulations were applied with using motorized knapsack atomizer sprayer and with hands respectively. The treatments included delthametrin EC 2.5%, fenitrothion EC50%, fenitrothion G 5%, fenitrothion CS 20%, fipronil G 0.2% and check, that their effectiveness in controlling on sunn pest adults, new generation adults and nymphs were studied. The delthametrin EC 2.5% was more effective than the other treatments. Most treatments were not able to reduce damaged in the standard level (2%). Thus applying of pyrethroid insecticides such as delthametrin with micro capsulated suspension (CS) formulation can be more affected in chemical control of overwintered adults.

The polyphagous predatory mite Amblyseius swirskii preys on both of these pests. In this research, predation of the predatory mite on different stages of both pests, prey stage preference of pests, prey preference and switching behavior of predator between preferred stage of greenhouse whitefly and two-spotted spider mite were investigated in laboratory conditions (25 ± 1°C, 70 ± 10% RH and 16L: 8D hour photoperiod). The preference index for each experiment was calculated by Manly’s β index. Results showed that, young instars (first and second instars) of greenhouse whitefly and non-sessile stages of spider mites (larvae, protonymph and deuonymph) were preferred stages. Comparison of the mean preference index between young instars of greenhouse whitefly and protonymphs of two-spotted spider mite showed that this predator showed a significant preference to T. urticae. The variation in different ratio of preys had no effect on predatory mite preference so switching didn’t observed in A. swirskii.
