In this study, two antagonistic fungi were isolated from cadavers of <em>Spodoptera litura</em> and <em>Mythimna separata</em>, and were identified as <em>Trichoderma afroharzianum</em> and <em>Trichoderma asperelloides</em>. The mycelia of <em>T. afroharzianum</em> grew fastest on the PSA medium under all light conditions, with soluble starch and peptone serving as the optimal carbon and nitrogen sources, respectively. The optimal pH was 6.0 and the lethal temperature was 57°C. The mycelia of <em>T. asperelloides</em> grew fastest on the PDA medium under all light conditions, with maltose and peptone as the optimal carbon and nitrogen sources, respectively. The optimal pH was 5.0 and the lethal temperature was 58°C. The two strains demonstrated antifungal activity against four apple disease pathogens: <em>Alternaria mali</em>, <em>Collectotrichum gloeosporioides</em>, <em>Botryosphaeria dothidea</em>, and <em>Valsa mali</em>. Antagonistic culture results showed that <em>T. afroharzianum</em> achieved an inhibition percentage exceeding 55 % against all four pathogens, while <em>T. asperelloides</em> exhibited the highest antifungal activity against <em>B. dothidea</em> (67.66 %). The mechanisms for controlling apple pathogens were investigated by measuring the activities of Poly Galacturonase (PG) and β-glucosidase (β-GC). In <em>B. dothidea</em>, the activities of PG and β-GC decreased by 58.92 % and 79.54 % when treated with <em>T. afroharzianum</em> culture filtrates, and decreased by 49.28 % and 89.02 % when treated with <em>T. asperelloides</em> culture filtrates, respectively.

This increases the need of biodiversity driven pest management strategies especially for wheat, one of the main food crops, worldwide. In Pakistan, which is comprised in area origin of wheat, we evaluated the biological control potential of canola-wheat strip cropping and alternate row intercropping compared to wheat sole cropping against wheat aphids in crop seasons of 2021 and 2023 in organic and conventional fields. Abundance, evenness and diversity of aphids and natural enemies were lower and higher, respectively, in alternate-row intercropping compared to wheat monocrop in both conventional and organic farm types. Contrarily, pest richness was similar among cropping systems in both farming types in 2023, but natural enemies’ richness was greater in intercropped plots in both the years. Natural enemies’ density and diversity indices proved to be strong predictors of aphid suppression in the fields. Increased enemies and reduced aphids in the diversified systems show positive complementarity among the enemies having different hunting behaviours and suggest the acquisition of floral and prey resources provided by canola.

In total, 30 yeast strains were isolated from fruits, leaves and soil of two citrus orchards. Subsequently, 8 yeast strains tested <em>in vivo</em> effectively inhibited green mold in citrus fruit, with <em>Kurtzmaniella quercitrusa</em> BS-AY-S1 achieving the best biocontrol efficacy by reducing the disease incidence (DI) by 58.33 % and lesion diameter (LD) by 73.36 % compared to the control on the 6th day.

The fermentation supernatant of BS-AY-S1 effectively inhibited the growth of <em>P. digitatum</em> and controlled green mold in citrus fruit. Additionally, the volatile organic compounds (VOCs) from BS-AY-S1 markedly reduced the spore germination, spore production and mycelial growth of <em>P. digitatum</em>, and slowing down the progression of green mold in citrus fruit.

However, the resistance mechanism that appears to be primarily responsible for resistance in the weevil, enhanced enzymatic detoxification, may have the potential to deactivate compounds produced by the nematodes’ symbiotic bacteria that play important roles in the infection process. We compared the efficacy of several nematode species for the management of weevil larvae in populations with different insecticide resistance levels. The resistance level in weevil populations was defined based on the resistance ratio (RR₅₀) of the pyrethroid insecticide bifenthrin. In greenhouse experiments, reduced nematode efficacy, particularly of the species <em>Steinernema feltiae</em> and <em>S. carpocapsae</em>, was already observed at moderate resistance levels (RR₅₀ 55–76) with reduction in efficacy of 20–32%.

Citrus packhouses in South Africa have reported lower infestation of <em>T. leucotreta</em> in fruit from organically farmed orchards than conventionally farmed orchards. Therefore, field surveys were conducted to determine if <em>T. leucotreta</em> infestation was lower on organic citrus farms and to compare natural enemy abundance and species richness between the two farming types. In pheromone trap field surveys, wild adult <em>T. leucotreta</em> numbers were significantly higher in conventionally farmed Palmer Navel and Newhall Navel orange orchards than in matching orchards on neighbouring organic farms. Pitfall trapping recorded significantly higher arthropod generalist predator abundance and species richness in organic farms. Organic orchards had a mean of 7.3 (± 0.6, standard error (SE)) distinct predatory species per trap whereas in conventional orchards 3.9 (± 0.4) species were recorded per trap.
