Specimens of the broad-leaved conifer, Liaoningocladus boii Sun, Zheng & Mei 2000 were evaluated from the mid Early Cretaceous Yixian Formation occurring overwhelmingly at Dawangzhangzi, Liaoning Province, NE China. Arthropod-mediated plant damage types (DTs) were categorized for 343 specimens of this host; one of these DTs represented a distinctive leaf-mine, DT280, established as Fossafolia o...

the use of resistant plant cultivars and parasitoids could be an effective strategy in ipm of liriomyza sativa blanchard. cucumber is a preferable host for this insect. in this research, antixenosis resistance of 17 cultivars of cucumber was evaluated to l. sativae under greenhouse condition. results indicated that there were significant differences between cultivars with regard to the number o...

The tomato leaf miner Phthorimaea absoluta(Meyrick), earlier known by the scientific name Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of most devastating global pests tomatoes. Using indigenous entomopathogenic fungi can be a promising solution to manage it. Effıcacyof EPF isolates on third-instar larvae was carried out in Ethiopia during 2021-2022. Ten were inoculated with conidi...

The laminae of leaves optimize photosynthetic rates by serving as a platform for both light capture and gas exchange, while minimizing water losses associated with thermoregulation and transpiration. Many have speculated that plants maximize photosynthetic output and minimize associated costs through leaf size, complexity, and shape, but a unifying theory linking the plethora of observed leaf f...

What causes the domesticated tomato Solanum lycopersicum to have sweet, juicy red fruit and large, compound leaves with narrow-tipped leaflets while its distant wild relative, the Peruvian Solanum pennellii, has small, soapy-smelling green fruit with an unpleasant flavor (Matsui et al., 2007) and small compound leaves with thick, rounded leaflets (see figure)? Thoroughly answering this question...

Genomic characterization using nonradioactive probes, polymerase chain reaction with degenerate primers for whitefly transmitted geminiviruses and nucleotide sequencing were used to describe a new bipartite geminivirus, associated with dwarfing and leaf curling of tomatoes and peppers in Jamaica. Partial DNA-A and DNA-B clones were obtained. DNA sequence analysis showed that tomato and pepper s...

Groundnut leaf miner (Aproaerema modicella. D.) is an important feeding insect in groundnut that significantly reduces the pod yield up to 50 per cent. The growth and development of this pest closely associated with abiotic weather parameters prevailing a particular location. Due paucity information available on population dynamics factors, study was undertaken Erode district Tamil Nadu during ...
