The diversity, abundance and ecological distribution of dry date (Phoenix dactylifera L. (Arecales: Arecaceae)) pests and associated natural enemies were investigated along with date infestation rates, fruit damage levels and existing correlations in Zaria, northern Guinea Savannah Agroecological Zone (nGSAZ), Nigeria. Dry dates (three cultivars: Dan-Agadez, Dan-Hausa and Deglet) were sampled in eight locations, over eight months in 2018, for laboratory observations. Eight pest species (6 coleopterans and 2 lepidopterans) and 14 natural enemies (10 parasitoid and four predator species) were recovered. Pest richness (S, 4–7), diversity (H′, 0.62–1.55), evenness (J’, 0.38–0.79) and dominance (1/d, 1.20–2.82) per month/cultivar were low to moderate, while natural enemy richness (S, 5–12), diversity (H', 1.15–1.90), evenness (J’, 0.59–0.82) and dominance (1/d, 1.60–3.48) per month/cultivar were moderate to slightly high. Total date infestation rates (19%-30%) and fruit damage levels (11%-15%) did not vary significantly with location, month or cultivar. Abundance of most natural enemies (11 species) correlate positively with abundance of at least one of four pest species (Cadra cautella (Walker), 9 species; Oryzaephilus mercator (Fauvel), 8 species; Carpophilus dimidiatus (Fabricius), 6 species; and Tenebroides mauritanicus (L.), 1 species). Further, abundance of a few species (i.e., Brachymeria sp. and Phanerotoma sp. nr. philippinensis) correlate either positively or negatively with date fruit moisture content and relative humidity. In conclusion, predominant dry date pests and related natural enemies in the nGSAZ are respectively O. mercator > C. cautella/Lasioderma serricorne (F.) and Cephalonomia sp. > Pheidole sp. Collectively, recovered pests were responsible for moderate infestation rates and low fruit damage levels. Correlation results emphasize the need to further comprehend the functional response/efficiency of all natural enemies of dry date pests, as influenced by both abiotic and biotic factors.

调查了干枣（Phoenix dactylifera L.（Arecales：Arecaceae））害虫和相关天敌的多样性、丰度和生态分布，以及几内亚北部萨凡纳农业生态区（nGSAZ）的枣侵染率、果实损害水平和现有相关性），尼日利亚。2018 年在八个多月的时间里，在八个地点对干枣（三个品种：Dan-Agadez、Dan-Hausa 和 Deglet）进行了实验室观察。共发现了 8 种害虫（6 种鞘翅目和 2 种鳞翅目）和 14 种天敌（10 种寄生物和 4 种捕食者）。害虫丰富度 ( S , 4–7)、多样性 ( H' , 0.62–1.55)、均匀度 ( J' , 0.38–0.79) 和优势度 ( 1/d, 1.20–2.82) 每月/品种为低至中等，而天敌丰富度 ( S , 5–12)、多样性 ( H' , 1.15–1.90)、均匀度 ( J' , 0.59–0.82) 和优势度 (1/ d , 1.60–3.48) 每月/栽培品种中等至略高。总日期侵染率 (19%-30%) 和果实损害水平 (11%-15%) 没有显着不同的地点、月份或品种。最天敌（11种）正与丰度的4个害虫物种的至少一种（有相互关系丰度CADRA cautella（沃克），9种;锯谷麦卡托（Fauvel），8种; Carpophilus dimidiatus（法氏囊），6种;和毛里塔尼科黄粉虱(L.), 1 种)。此外，少数物种（即Brachymeria sp. 和Phanerotoma sp. nr. philippinensis）的丰度与枣果水分含量和相对湿度呈正相关或负相关。总之，nGSAZ 中主要的干枣害虫和相关天敌分别是O. mercator  >  C. cautella / Lasioderma serricorne (F.) 和Cephalonomia sp。> 菲多尔sp. 总的来说，恢复的害虫是造成中等侵染率和低果实损伤水平的原因。相关结果强调需要进一步了解受非生物和生物因素影响的所有干枣害虫天敌的功能反应/效率。
