Temperature-induced effects on development, reproduction, and predation of fed on first instar larvae .

Since metabolism, survival, and reproduction in hexapods are closely related to temperatures; changes in the mean and variance of temperature are major aspects of global climate change. In the typical context of biological control, understanding how predator-prey systems are impacted under thermal conditions can make pest control more effective and resilient. With this view, this study investigated temperature-mediated development and predation parameters of the predator against the potential prey .

Effect of temperature on the life cycle of Harmonia axyridis (Pallas), and its predation rate on the Spodoptera litura (Fabricius) eggs.

Biological control is one of the strategies of pest control which is determined by the biological fitness and metabolic rates of the predator species used. Temperature and resource are important factors which influence the role of insects as biocontrol agents. Harmonia axyridis is a cosmopolitan and non-specific polyphagous predator.

Functional Response of to the Larvae of : The Combined Effect of Temperatures and Prey Instars.

Functional responses are central to predator-prey dynamics and describe how predation varies with prey abundance. Functional responses often are measured without regard to prey size (i.e.

Functional response of Harmonia axyridis preying on Acyrthosiphon pisum nymphs: the effect of temperature.

In the current study, we investigated the functional response of Harmonia axyridis adults and larvae foraging on Acyrthosiphon pisum nymphs at temperatures between 15 and 35 °C. Logistic regression and Roger's random predator models were employed to determine the type and parameters of the functional response. Harmonia axyridis larvae and adults exhibited Type II functional responses to A.

Predatory functional response and fitness parameters of Poppius when fed and as determined by age-stage, two-sex life table.

Background: The polyphagous predatory bug is an active predator used to control thrips and aphids. The whitefly species and are voracious pests of different economic agricultural crops and vegetables.

Method: In this study, the Holling disc equation and the age-stage, two-sex life table technique were used to investigate the functional response and biological traits of third instar nymphs and adult female when presented third instar nymphs of both whitefly species as prey.

Temperature-Dependent Functional Response of (Coleoptera: Coccinellidae) on the Eggs of (Lepidoptera: Noctuidae) in Laboratory.

(Fabricius) (Lepidoptera: Noctuidae) is a major pest of several economically important crops with worldwide distribution. Use of insecticides is the principal strategy for its management, which has subsequently led to insecticide resistance and control failures. Functional response of (Pallas) (Coleoptera: Coccinellidae) at larval and adult stages was evaluated in this study, using eggs as the prey at various temperatures varying between 15 and 35 °C.

Determination of fitness traits of Poppius (Hemiptera: Anthocoridae) on (Lepidoptera: Gelechiidae) using two-sex life table analysis.

Background: Pink bollworm () is a destructive insect pest of cotton crops in China and globally, which is actively predated on by . Studies on the fitness or survival of fed on at different temperatures have not been reported. The fitness of may be well explained using two-sex life table parameters.

Lethal and Sublethal Effects of Chlorpyrifos on Biological Traits and Feeding of the Aphidophagous Predator .

Except of pest control, insecticides have shown adverse effects on natural enemies as well. Thus, risk assessment of pesticides for biological control agents is critical for effective use in integrated pest management (IPM) schemes. In the present study, the lethal and sublethal effects of chlorpyrifos, a commonly used insecticide that may negatively affect biological control agents, were evaluated on a non-target predator, the Asian ladybeetle .
