Resistance to 2-tridecanone in Tetranychus urticae: effects of induced resistance, cross-resistance and heritability

Efstratios A. Chatzivasileiadis, Martijn M. Egas, Maurice W. Sabelis

Experimental and Applied Acarology > 2001 > 25 > 9 > 717-730

Earlier studies of resistance to the tomato toxin 2-tridecanone revealedsimilar levels of resistance among tomato and cucumber strains ofTetranychus urticae, whereas we anticipated the tomatostrains to have a higher resistance. Between-strain differences, however, maybeconcealed by toxin accumulation and/or cross-resistance. Mites do accumulate2-tridecanone to a considerable extent, but we have shown...

The natural control of the tracheal mite of honey bees

L. Bailey, J.N. Perry

Experimental and Applied Acarology > 2001 > 25 > 9 > 745-749

The natural control of the tracheal mite, Acarapiswoodi, of the honey bee depends greatly on good foragingopportunities for bee colonies and on limited competition between colonies. Thesevere, widely-publicised disease of bees, referred to as ‘the Isle ofWight disease’ in Britain early in the last century when colonies weremore numerous than subsequently, was wrongly attributed to the mite, whichcauses...

The pest status and distribution of three cryptic blue oat mite species (Penthaleus spp.) and redlegged earth mite (Halotydeus destructor) in southeastern Australia

Michelle T. Robinson, Ary A. Hoffmann

Experimental and Applied Acarology > 2001 > 25 > 9 > 699-716

Earth mites are pests of crops and pastures in southeastern Australia.Recent studies show differences between earth mite species in their mode ofreproduction, preferred hosts and pesticide tolerance. This paper examines thedistribution and pest status of each species. The southeastern Australiandistribution for each species is mapped, incorporating new data from easternNewSouth Wales, South Australia...

Population dynamics of interacting predatory mites, Phytoseiulus persimilis and Neoseiulus californicus, held on detached bean leaves

A. Walzer, S. Blümel, P. Schausberger

Experimental and Applied Acarology > 2001 > 25 > 9 > 731-743

The success of combined release of the predatory mitesPhytoseiulus persimilis and Neoseiulus californicus insuppression of spider mites may be related to the effects of the interactionsbetween the two predators on their population dynamics. We studied populationgrowth and persistence of the specialist P. persimilis andthe generalist N. californicus reared singly versus rearedin combination after simultaneous...

Abnormal development of Rhipicephalus sanguineus (Ixodidae)

Agustín Estrada-Peña

Experimental and Applied Acarology > 2001 > 25 > 9 > 757-761

Three malformed Rhipicephalus sanguineus specimenswere noticed in a tick laboratory colony. These specimens had different degreesof twining, from an almost fused individual (with two anal pores) to apartiallyfused adult male, with four spiracular plates. One female was a heart-shapedspecimen, with both body halves fused along a longitudinal axes, with fourspiracular plates and two anal pores.

Life-Cycle of Suidasia Medanensis (= pontifica) (Acari: Suidasiidae) under Laboratory Conditions in a Tropical Environment

Dilia Mercado, Leonardo Puerta, Luis Caraballo

Experimental and Applied Acarology > 2001 > 25 > 9 > 751-755

The life cycle of Suidasia medanensis (= pontifica) was studied under laboratory conditions at 26°C and 86% relative humidity. Freshly laid eggs were observed until they developed into adults and the periods between stages were recorded. Production of eggs by mated females was monitored until they died. The eggs required an average of 12.6 ± 0.6 days to develop into adults. Mean longevity of mated...
