Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).

Review of the southern African slender stonebashers, genus Heteromormyrus Steindachner 1866 (Teleostei: Mormyridae), with description of six new species

open access: yesJournal of Fish Biology, EarlyView.
Abstract Recent molecular studies have advanced our knowledge of the taxonomic diversity and generic placement of the slender stonebashers, previously placed in the genus Hippopotamyrus, in southern Africa. These fishes were recently transferred to the genus Heteromormyrus whose range encompasses the Kwanza, Kunene, Okavango, Zambezi, Pungwe and Buzi ...

Predator mite application methods for biological control of twospotted mites in hops

open access: yesNew Zealand Plant Protection, 2007
The efficacy of a novel air stream predator mite application method for the control of twospotted mites (TSM Tetranychus urticae) in hops was compared with a standard teaspoon release method Predator mites (Phytoseiulus persimilis) were successfully established with a single release using both application methods and TSM declined to low numbers during ...

Dread in the Homeland: Symbolic Politics and Ethnonationalist Struggles for Self‐Determination in Nigeria

open access: yesNations and Nationalism, EarlyView.
ABSTRACT The revival of Biafran separatism in contemporary Nigeria is often explained with three leading theoretical frameworks: relative deprivation, political economy and state repression. Whereas relative deprivation and political economy perspectives posit that the resurgent separatism derives from the perception and empirical reality of ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Spatial and temporal distribution of Eotetranychus frosti and Cenopalpus irani and their predator Typhlodromus bagdasarjani in an unsprayed apple orchard at Khorramabad, Western Iran

open access: yesPersian Journal of Acarology, 2014
The spatial and temporal distribution of Eotetranychus frosti (McGregor), Cenopalpus irani Dosse, and their dominant predator Typhlodromus bagdasarjani Wainstein & Arutunjan were studied in an unsprayed apple orchard in Chaghalvandi region (Lorestan ...

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

open access: yesPlant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.

A Holling-Tanner predator-prey model with strong Allee effect

open access: yes, 2019
We analyse a modified Holling-Tanner predator-prey model where the predation functional response is of Holling type II and we incorporate a strong Allee effect associated with the prey species production.
