The Reflex “Bleeding” of the Coccinellid Beetle, Epilachna Borealis.

Annals of the Entomological Society of America, 1916
It is a well-known fact among entomologists that when disturbed certain coccinellid and meloid beetles fold the antennae and legs against the body, eject small drops of liquid from the femoro-tibial articulations and feign death. There has been quite a controversy as to how the liquid is expelled so quickly and as to whether the liquid is blood or is a

Evaluating Syrphid Fly Predation on Aphids Under Controlled and Field Conditions in High Tunnels: A Comparative Study With Lacewings

Journal of Applied Entomology, Volume 150, Issue 6, Page 693-705, July 2026.
ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

Prey-Mediated Effects of Drought on the Consumption Rates of Coccinellid Predators of Elatobium abietinum

Insects, 2016
Climate change in the UK is predicted to cause an increase in summer drought events. Elatobium abietinum is an important pest of Sitka spruce (Picea sitchensis), causing defoliation of trees, and is predicted to become more abundant in response to ...

Insectary Plant Species Preferences of Predators and Parasitoid Families in a Mediterranean Horticultural Agroecosystem

Journal of Applied Entomology, Volume 150, Issue 6, Page 803-815, July 2026.
ABSTRACT The use of insectary plants to provide alternative food and shelter resources for enhancing natural enemy activity has been established as a common practice in IPM. Candidate flowering plant species have been screened and evaluated for their contribution to enhance life parameters of beneficial insects.

Biological control in agroecosystems: the case of Coccidophagy by Coccinellids

, 2012
Coccinellids are important natural enemies that provide ecosystem services, such as the biological control of pests, in multiple cropping systems. Scales are essential prey items for a large proportion of coccidophagous coccinellid species.

Influence of different species of aphid prey on the immature survival and development of four species of aphidophagous coccinellids (Coleoptera: Coccinellidae)

European Journal of Entomology, 2015
This study was on the effect of three species of aphids (Aphis fabae, Macrosiphoniella sanborni, Brevicoryne brassicae) on the survival, growth and development of the immature stages of the aphidophagous coccinellids Coccinella septempunctata ...

Selective toxicity of diafenthiuron to non-target organisms: honey bees, coccinellids, chelonus, earthworms, silkworms and fish

Journal of Plant Protection Research, 2016
Diafenthiuron, an insecticide widely used in the management of pests of cardamom and cotton, was assessed for its toxicity-effect on beneficials commonly found in these ecosystems.
