Entomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1165-1176, November 2025.The noctuid pest western bean cutworm (Striacosta albicosta) lays its eggs in corn fields over the season. Various generalist predators consume the eggs and larvae of this pest. To improve integrated pest management of S. albicosta, this study identified key trophic interactions between S. albicosta and predatory arthropods in corn fields.

European Journal of Entomology, 2008 A laboratory experiment was conducted to determine whether the predation strategy of larvae of the aphidophagous silver fly Leucopis annulipes Zetterstedt (Diptera: Chamaemyiidae) is furtive, as are larvae of the aphidophagous midge Aphidoletes ...

Interspecific differences of ladybirds (Coleoptera: Coccinellidae) in their repellency to ants
Journal of Zoology, Volume 327, Issue 1, Page 73-83, September 2025.Our study found that, unlike those from mealworms, compounds in whole‐body extracts of ladybirds effectively deterred ants. No correlation was found between the degree of aposematic colouration (highly conspicuous vs. less conspicuous) and repellence. Mycophagous ladybird species exhibited levels of protection comparable to predatory species, and large

Agricultural and Forest Entomology, Volume 27, Issue 3, Page 463-475, August 2025.Abstract Invasive eucalypt psyllids pose a threat to the long‐term production of eucalypts worldwide. In order to reduce their economic impact, classical biological control using Psyllaephagus species has been used successfully. The objectives of this study were to determine the host specificity and host stage preference of Psyllaephagus blastopsyllae,

ESTABLISHMENT OF ACYRTHOSIPHON PISUM (HARRIS) (HEMIPTERA: APHIDIDAE) IN NEW SOUTH WALES [PDF]
Australian Journal of Entomology, 1984 Abstract Acyrthosiphon pisum (Harris) pea aphid was first detected in New South Wales at Yanco in January 1980. A survey conducted in March and May 1980 indicated that A. pisum was restricted to the southern areas of N.S.W. A second survey in June 1981 showed A. pisum had spread to all except 1 of the major lucerne growing areas of the State.

Bulletin of Entomological Research, 1955 The effect of photoperiod and temperature on the production of the various forms of Acyrthosiphon pisum (Harris) has been studied. In this study apterous virginoparous females were exposed throughout their lifetime to two photoperiods (8 hr./24 hr. and 16 hr./24 hr.) and six different temperatures. At each of the temperatures the apterae (parent Aphids)

Biological Flora of Britain and Ireland: Cytisus scoparius*
Journal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.
