Record of the invasive alien ladybird Harmonia axyridis (Coleoptera, Coccinellidae) from Kenya

open access: yesZooKeys, 2011
The biological control agent and alien invasive ladybird Harmonia axyridis (Pallas, 1773) was recorded for the first time in Kenya, and in equatorial Africa, in 2010.

Mortality of native and invasive ladybirds co-infected by ectoparasitic and entomopathogenic fungi [PDF]

open access: yesPeerJ, 2020
Harmonia axyridis is an invasive alien ladybird in North America and Europe. Studies show that multiple natural enemies are using Ha. axyridis as a new host.

A roadmap to key traits of invasive Drosophilidae

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Antagonistic interactions between an invasive alien and a native coccinellid species may promote coexistence [PDF]

open access: yes, 2016
1. Despite the capacity of invasive alien species to alter ecosystems, the mechanisms underlying their impact remain only partly understood. Invasive alien predators, for example, can significantly disrupt recipient communities by consuming prey species ...

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

open access: yesPest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

The multicolored Asian lady beetle : Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) ; a not so new invasive insect in Colombia and South America [PDF]

open access: yes, 2013
The first reports of the multicolored Asian lady beetle Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) in Colombia appeared in 2011. However, based on museum insect specimens, the introduction of H.

The influence of surface energy on the self-cleaning of insect adhesive devices [PDF]

open access: yes, 2012
The ability of insects to adhere to surfaces is facilitated by the use of adhesive organs found on the terminal leg segments. These adhesive pads are inherently 'tacky' and are expected to be subject to contamination by particulates, leading to loss of ...

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

open access: yesInsect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

open access: yesInsect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.
