Spondyliaspis cf. plicatuloides (Froggatt) (Hemiptera: Aphalaridae) is native to Australia but was first detected outside its range in 2014, South Africa. It feeds on eucalypt species and thus has the potential become a pest commercial Eucalyptus plantations. Information basic biology of this insect, which important for development surveillance management strategies, lacking. To investigate lif...

The population biology of three populations of Panstrongylus megistus was compared to determine possible influence on the behaviour and epidemiological importance of this species. The results demonstrated differences in terms of egg eclosion time, nymphal mortality and development rates, and feeding and defaecation rates. These differences appeared to follow a geographical cline, primarily refl...

Flavescence dorée (FD) is a grapevine disease caused by associated phytoplasmas (FDp) which are epidemically spread their main vector Scaphoideus titanus. The possible roles of alternative and secondary FDp plant hosts vectors have gained interest in terms better understanding the ecology epidemiology. findings survey conducted surroundings three vineyards southern Swiss Alps aimed at studying ...

the outbreak of sugarcane whitefly, neomaskellia andropogonis corbett has been recently recorded in sugarcane fields in khuzestan province. the seasonal population dynamics of n. andropogonis was investigated in sugarcane fields (cultivar cp69-1062) in amir kabir agro-industrial in khuzestan during 2006-2007. one hectar field in the middle of a large field (25 hectar areas) was selected randoml...

Like other praying mantises, Hierodula membranacea has a single midline ear on the ventral surface of the metathorax. The ear comprises a deep groove with two tympana forming the walls. A tympanal organ on each side contains 30-40 scolopophorous sensillae with axons that terminate in the metathoracic ganglion in neuropil that does not match the auditory neuropil of other insects. Nymphal develo...

Behaviors of Eretmocerus sp. nr. californicus females attacking Bemisia argentifolii Bellows & Perring infesting cotton, Gossypium hirsutum L., and melon, Cucumis melo L., were quantified. Adult female behaviors were described and quantified for Eret. sp. nr. californicus to establish a behavioral time budget analysis. Females readily searched for host whitefly nymphs on cotton leaves with walk...

Biological control is occasionally supplemented with insecticides treatments, which may have a significant impact on natural enemies. Typically, selective compounds are chosen to overcome lack of compatibility, but an alternative approach the use biocontrol agents resistant pesticides. Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) main predator used thrips and other small pests in greenho...

Leptoglossus zonatus (Dallas) (Hemiptera: Coreidae) has recently emerged as a key pest of satsuma mandarin, Citrus unshiu Marcovitch, and other fruit crops in the Gulf Coast region of the United States. Studies were conducted under laboratory conditions (25 +/- 2 degrees C, 50 +/- 10% RH, and a photoperiod of 14:10 [L:D] h) to investigate host preference and suitability of satsuma fruit as host...
