Insects and Survival: A Review of Primary and Secondary Defense Strategies
Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Journal of Agronomy and Crop Science, Volume 212, Issue 4, July 2026.ABSTRACT A selection of winter barley genotypes was investigated for their responses to water shortage under different CO2 concentrations in a greenhouse. The experiment was conducted in a 2*2 factorial design. Plants were grown either with optimum water supply or simulated drought in the BBCH 59 stage at current (~400 ppm CO2) or elevated CO2 ...

Drought Stress Promotes Aphis gossypii Growth but Decreases Host Attractiveness in Melon
Journal of Applied Entomology, Volume 150, Issue 6, Page 770-779, July 2026.ABSTRACT Drought stress is a significant environmental factor that affects plant physiology and growth, leading to considerable detrimental effects on crop productivity. Cucumis melo, which is widely cultivated for its economic value, is particularly susceptible to water scarcity.

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.Abstract The low yield of cowpeas (Vigna unguiculata (L.) Walp.) in sub‐Saharan Africa is credited to several limitations, including poor soil fertility and unsustainable cropping systems. Cereals like maize (Zea mays L.) and legume crops like cowpea support smallholder farmers in sub‐Saharan Africa. Intercropping (more common than rotations) can boost

Was Dan Janzen (1977) right about aphid clones being a "super-organism", i.e. a single "evolutionary individual"? : new insights from the use of molecular marker systems [PDF]
, 2008 Dan Janzen proposed in a paper in 1977 (loc. cit.), that a clone of aphids and for that matter dandelions consists, respectively, of one large ‘super-organism’.

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.Abstract An intercropping system is one of the traditional practices adopted under dry conditions due to its ability to utilize resources efficiently. There is limited information on water use efficiency (WUE) and water equivalent ratio (WER) of grain sorghum (Sorghum bicolor)‐cowpea (Vigna unguiculata) intercrop grown in different agroecological ...

Phenotyping of cereal grasses as food resources for the bird cherry-oat aphid Rhopalosiphum padi
Труды по прикладной ботанике, генетике и селекцииBackground. Cereal grasses are an integral component of not only natural but also anthropogenic cenoses as weeds or cultivated crops. Of these, 183 species are included in the range of food plants for the bird cherry-oat aphid Rhopalosiphum padi (L ...
