Effect of temperature on biology and population growth parameters of Aphis gossypii Glover (Hom., Aphididae) on greenhouse cucumber
TLDR
Three mathematical models were compared for accuracy in predicting the developmental rate of A. gossypii, and estimating its temperature thresholds and optima, and the Briere 2 and Lactin 2 models were accepted for success to satisfy criteria of goodness‐of‐fit and estimable temperature threshold parameters.

Temperature-dependent functional response of two aphid parasitoids, Aphidius colemani and Aphidius matricariae (Hymenoptera: Aphidiidae), on the cotton aphid
TLDR
The results showed that instantaneous attack rate in A.colemani increased linearly as the temperature increases from 10 to 30°C, but in the case of A.matricariae, increased almost linearly with temperature to reach a maximum at 25 °C, and then decreased at 30° C, displaying an asymmetrical dome-shaped pattern, which suggests that A. cole mani maybe more effective for biological control of the cotton aphid during warmer periods.

Effect of Temperature on Life History of Aphidius colemani and Aphidius matricariae (Hymenoptera: Braconidae), Two Parasitoids of Aphis gossypii and Myzus persicae (Homoptera: Aphididae)
TLDR
The Lactin 2 and Briere 1 developmental models were accepted based on their excellent goodness-of-fit to the data (residual sum of square and coefficient of determination) and estimable temperature thresholds and are strongly recommended for the description of temperature-dependent development of A. colemani and A. matricariae.

Assessment of heavy metal pollution in surficial soils surrounding Zinc Industrial Complex in Zanjan-Iran
Abstract In this study the Zinc Industrial Complex located near the city of Zanjan-Iran was selected for detailed study. The objective of the study was to assess the extent and severity of heavyExpand
Life Parameters of Tetranychus urticae (Acari: Tetranychidae) on Six Common Bean Cultivars
TLDR
It was revealed that white beans (Pak and G11867) were less suitable cultivars, suggesting that they are more resistant to the twospotted spider mite than the other cultivars. Expand
LIFE HISTORY AND DEMOGRAPHIC PARAMETERS OF APHIS FABAE (HEMIPTERA: APHIDIDAE) AND ITS PARASITOID, APHIDIUS MATRICARIAE (HYMENOPTERA: APHIDIIDAE) ON FOUR SUGAR BEET CULTIVARS
TLDR
The use of Shirin cultivar is suggested to maximize the natural biological control of A. fabae and A. matricariae as a step toward Biological control of black bean aphid. Expand
Host Plants Effect on Preference , Development and Reproduction of Plutella xylostella ( L . ) ( Lepidoptera : Plutellidae ) Under Laboratory Conditions
The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) is the most destructive and cosmopolitan pest on brassicaceous crops. In this study, the development and reproduction ofExpand
Side effects of spiromesifen and spirodiclofen on life table parameters of the predatory mite, Neoseiulus californicus McGregor (Acari: Phytoseiidae)
TLDR
Considering the effects of the acaricides on the population growth of Neoseiulus californicus, spiromesifen and spirodiclofen should be used cautiously in conjunction with N. califORNicus to achieve efficient control of T. urticae management. Expand
Concentration, Distribution and Comparison of Total and Bioavailable Metals in Top Soils and Plants Accumulation in Zanjan Zinc Industrial Town-Iran
Abstract Heavy metal contamination of metal-mined soils is a widespread problem in parts of Zanjan province. The province located in North West of Iran is highly polluted by heavy metals due to theExpand
