Parallel Losses of Blue Opsin Correlate with Compensatory Neofunctionalization of UV-Opsin Gene Duplicates in Aphids and Planthoppers

Insects, 2023
Expanding on previous efforts to survey the visual opsin repertoires of the Hemiptera, this study confirms that homologs of the UV- and LW-opsin subfamilies are conserved in all Hemiptera, while the B-opsin subfamily is missing from the Heteroptera and ...

Development of an Artificial Liquid Diet for Allelochemical Delivery in Lycorma delicatula

Journal of Applied Entomology, EarlyView.
ABSTRACT Spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is an invasive phloem‐feeding planthopper native to Asia, which poses a growing threat to US agriculture due to its broad host range and rapid spread since its 2014 detection. To better understand how L.

Three dimensional reconstruction of energy stores for jumping in planthoppers and froghoppers from confocal laser scanning microscopy

eLife, 2017
Jumping in planthopper and froghopper insects is propelled by a catapult-like mechanism requiring mechanical storage of energy and its quick release to accelerate the hind legs rapidly.

RNA-Sequencing Reveals Differentially Expressed Rice Genes Functionally Associated with Defense against BPH and WBPH in RILs Derived from a Cross between RP2068 and TN1

Rice, 2021
Background Rice is staple food for over two billion people. Planthoppers like BPH and WBPH occur together in most of rice growing regions across Asia and cause extensive yield loss by feeding and transmission of disease-causing viruses.

Oviposition Behaviour, Nymphal Development and Below‐Ground Olfactory Preference of Pentastiridius leporinus on 12 Beta vulgaris Genotypes

Journal of Applied Entomology, EarlyView.
ABSTRACT The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the primary vector of two phloem‐restricted prokaryotes, which can cause the disease syndrome de basses richesses (SBR) in sugar beet (Beta vulgaris L.). Heavy infestations of this insect have contributed to significant yield losses in Central Europe, but little is known about ...

THE EFFECT OF SOAKING DURATION OF TUBA ROOTS (Derris elliptica) ON THE MORTALITY OF THE WHITE-BACKED PLANTHOPPER PESTS (Metcalfa pruinosa)

Jurnal Pendidikan Matematika dan IPA
Tuba root (Derris elliptica) is a plant that contains rotenone in roots where this content functions as a poison for insects, so tuba root has the opportunity to be used as a vegetable pesticide in pest control activities.

MYB Factors: Hubs of Plant Stress and Hormone Crosstalk

Plant Biotechnology Journal, EarlyView.
ABSTRACT MYB transcription factors function as main regulatory hubs that integrate environmental signals with multi‐hormonal pathways to synchronize plant growth, metabolism and stress responses. This review delineates the regulatory roles of MYB in the signalling pathway of salicylic acid, jasmonic acid, ethylene and abscisic acid signalling.

A Comparative Analyses of the Complete Mitochondrial Genomes of Fungal Endosymbionts in Sogatella furcifera, White-Backed Planthoppers

International Journal of Genomics, 2021
Sogatella furcifera Horvath, commonly known as the white-backed planthoppers (WBPH), is an important pest in East Asian rice fields. Fungal endosymbiosis is widespread among planthoppers in the infraorder Fulgoromorpha and suborder Auchenorrhyncha.

Jumping performance of planthoppers (Hemiptera, Issidae) [PDF]

Journal of Experimental Biology, 2009
SUMMARYThe structure of the hind limbs and the kinematics of their movements that propel jumping in planthopper insects (Hemiptera, Auchenorrhyncha,Fulgoroidea, Issidae) were analysed. The propulsion for a jump was delivered by rapid movements of the hind legs that both move in the same plane beneath the body and parallel to its longitudinal axis, as ...
