A sound IPM management for false codling moth (FCM), Thaumatotibia leucotreta, a devastating pest threatening horticultural production in Africa, is urgently needed. The compatibility of the dry conidia of virulent fungal isolate, Metarhizium anisopliae ICIPE 69 with FCM sex pheromone (Crytrack^®) in the autoinoculation was assessed. The effect of the pheromone on the conidial germination was monitored for 4 weeks under field conditions. The multilocation trial was implemented in Machakos and Makueni counties in Kenya to test the efficacy of M. anisopliae ICIPE 69 and Last Call FCM^® for T. leucotreta control in orange orchards. The treatments evaluated were (1) M. anisopliae ICIPE 69 (Campaign^® and dry conidia); (2) Last Call FCM^®; (3) M. anisopliae ICIPE 69 (Campaign^® and dry conidia) and Last Call FCM^®; and (4) Untreated control orchards. Results show that the conidial viability is not affected by the pheromone. For the multilocation FCM control trial, all treated orchards recorded a significant reduction in the FCM population and consequently fruit infestation, relative to the control (no intervention). FCM infested fruits were 18, 27, 5, and 49% in the treatments 1, 2, 3, and 4, respectively, in Machakos, and 24, 31, 7, and 54% for treatments 1, 2, 3 and 4 in Makueni. The highest marketable yield was recorded in orchards that received treatment 3 for both counties. The yield was 10,880.68 and 11,192.26 kg orange fruit/ha for Machakos and Makueni, respectively. The implication for the management of FCM is discussed in light of the findings of this study.

迫切需要对假co蛾（FCM）进行有效的IPM管理，它是威胁非洲园艺生产的毁灭性害虫。强毒分离株真菌的干分生孢子的相容性，金龟子绿僵菌ICIPE 69与FCM性信息素（Crytrack ^®在autoinoculation）进行了评估。在田间条件下监测信息素对分生孢子萌发的影响，持续4周。在多地点试验在马查科斯和马瓜尼县实施了肯尼亚测试的功效绿僵菌ICIPE 69和最后呼叫FCM ^®为T. leucotreta橙果园控制。评价的治疗方法是（1）绿僵菌ICIPE 69（运动^®和干分生孢子）; （2）最后通话FCM ^® ; （3）绿僵菌昆虫中心69（活动^®和干燥分生孢子）和最后呼叫FCM ^®; （4）未经处理的对照果园。结果表明，分生孢子的生存力不受信息素的影响。对于多地点FCM对照试验，相对于对照（无干预），所有处理过的果园均记录到FCM种群显着减少，从而导致果实侵染。在Machakos，处理1、2、3和4的受FCM侵染的水果分别为18％，27％，5％和49％，而处理1、2、3和4的FCM感染的水果分别为24％，31％，7％和54％马库尼 在两个县都接受了处理3的果园中，可销售的单产最高。Machakos和Makueni的橙色水果/公顷的产量分别为10,880.68和11,192.26 kg /公顷。根据这项研究的发现，讨论了FCM管理的意义。
