HYMENOPTEROUS PARASITOIDS OF PECAN LEAFMINERS1,2

open access: yes, 1985
Thirty-seven hymenopterous parasitoids, representing the families Braconidae, Encyrtidae, Eulophidae, and Eupelmidae were reared from the larvae and pupae of each of the pecan leafminers Stigmella juglandifoliella (Clemens) (Lepidoptera: Nepticulidae ...

Comparing species accumulation within taxonomically well‐ and poorly resolved insect groups over 37 years

open access: yesInsect Conservation and Diversity, EarlyView.
Here, we used a unique 37‐year (1969–2006) freshwater macroinvertebrate time‐series, collected over seven sites in central Germany, to study biodiversity patterns and species accumulation over time. Accumulation curves of Diptera diversity have not reached a plateau in 37 years of sampling.

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

open access: yesInsect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

The Parasitoid Complex of Aleurothrixus floccosus (Hemiptera: Aleyrodidae) in the Citrus Groves of Central–Southern Italy

open access: yesInsects
The woolly whitefly, Aleurothrixus floccosus, is likely a Neotropical origin species that has spread globally. Introduced to France in 1969, it became a pest in southern European citrus groves, first reported in Italy in 1974. Integrated management using

Conifer host identity shapes wood‐boring beetle communities more than climate across a latitudinal forest gradient in Quebec (Canada)

open access: yesInsect Conservation and Diversity, EarlyView.
Host tree identity and latitude shaped wood‐boring beetle assemblages, with species richness declining northward but community composition varying among regions and hosts. Host tree species influenced beetle communities more strongly than climate; black spruce supported the most species, while eastern hemlock hosted very few.

ABUNDANCE AND PARASITIC HABITS OF SOME PARASITOIDS OF THE NANTUCKET PINE TIP MOTH (LEPIDOPTERA: TORTRICIDAE)

open access: yes, 1979
Adult emergence curves of the Nantucket pine tip moth, Rhyacionia frustrana (Comstock), and 27 members of its parasitoid complex were compared for four generations in the Georgia piedmont. Based on numbers of emerging adults, parasitism of the three 1975

A Systematic Map to Identify Knowledge Gaps on a Vector of Citrus Greening Diseases: The African Citrus Triozid, Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...

First Record of Arrhenophagus chionaspidis Aurivillius (Hymenoptera: Encyrtidae) Parasitizing White Mango Scale in Kenya: Its Potential Distribution and Prospects in Biocontrol

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The white mango scale, Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae), is one of the most destructive pests of mango worldwide. Its current management in most of the invaded areas largely depends on the intensive use of chemical insecticides.

Host location in a specialist parasitoid wasp via olfactory cues – a physiological, behavioural and morphological study

open access: yes, 2012
For successful host location, parasitoids are thought to have evolved different strategies to filter relevant olfactory cues which indicate the presence of the host. Because of their versatility in their ecology and behaviour, as well as their fine tuned
