“…Locally prepared botanicals (5% neem seed kernel extract, 5% balanites Kernel extract) and imidacloprid 17.8% SL were found effective in managing the pests at three weeks post-foliar spray under eld evaluation. In similar way, soil and foliar use of thiamethoxam at 0.008% and foliar spray of imidacloprid at 0.009% found quite effective in managing psylla population(Rao et al 2013b). We observed that, spraying of insecticides on lower side of leaves during peak population checks the pest effectively.…”

Kinnow mandarin (Citrus reticulate Blanco) is one of the valuable fruit crops that mostly grown in North Indian states of India due to its high-quality juice content and resistant to decline. Pests psylla, whitefly, sooty mold and dieback damage new flush and fruits of mandarin are the most important biotic constraints affecting yield to the tune of 70 per cent. To manage these menace, farmers often resort to cocktail of pesticides without achieving the desired result. Hence, area wide implementation of Integrated Pest Management (IPM) in kinnow mandarin was implemented during 2021, 2022 and 2023 covering 5 villagesat Hisar, Haryana. The lowest average mean population of psylla and whitefly was recorded in IPM plots (4.82±4.69 no.of nymph and adult/10cm shoot and 2.80±1.56 no.of nymph and adult/leaf) compared to FP (6.67±3.15 no.of nymph and adult/10cm shoot and 3.89±1.51 no.of nymph and adult/leaf) and control (7.71±5.98 no.of nymph and adult/10cm shoot and 4.90±2.05 no.of nymph and adult/leaf) plots respectively. Similarly, minimum average mean disease severity of sooty mold and dieback was noticed in IPM plots (7.41±2.18 and 10.01±2.34%) compared to FP (9.31±2.97 and 12.11±2.65%) and untreated control (11.28±4.67 and 13.91±2.79%) plots. Likewise, low rate of Area Under Diseases Progress Curve (AUDPC) of sooty mold and dieback was observed in IPM followed by FP and in control plots. The Pearson correlation matrix reveals intricate relationships among the pests. The highest average fruit yield (t/ha) and B:C ratio was also recorded in IPM (22.46 & 4.34) compared to FP (18.88 & 3.16) and control (7.42 & 1.73). Besides, the IPM strategy has increased economic yield, the net profit by preventing pest resurgence, pesticide resistance, maintaining natural enemy diversity.

“…Diaphorina citri is a serious insect pest of citrus groves in different regions of the world. It was first reported in Taiwan [14] from where it invaded to many citrusgrowing regions of the world, including Brazil [15], India [16,17], Pakistan [18], Southern California [19], Texas [20], Florida [21], Australia [22], Colombia [23], Caribbean [24], Mexico [25], Indonesia [26], Iran [27], Kenya [28], Japan [29], Oman [30], Ethiopia [31], Malaysia [32], and Bangladesh [33].…”

Citrus are important commodities for human and animal nutrition but these crops are attacked by a plethora of dangerous agents, including viruses, bacteria, fungi, and invertebrates that decrease the yield significantly. Within invertebrates, insects are the more prevalent citrus pests causing plant damage or act as diseases vector. In this chapter, we focused in the insect pests with worldwide distribution in citrus orchards, including sap sucking Asian citrus psyllid Diaphorina citri, citrus mealybug Planococcus citri, citrus whitefly Dialeurodes citri, thrips representatives such as Scirtothrips citri and Pezothrips kellyanus, and chewing citrus leafminer Phyllocnistis citrella and lemon butterfly Papilio demoleus. These pests are distributed across various regions of different continents such as in Asia-pacific, Americas, Africa, and Oceana. We presented detailed data from these pests’ biology, ecology, damage, and methods for control. The pest incidence and biology is affected by various biotic and abiotic factors thus providing the opportunity to use these factors as method of intervention to disturb pest life cycle. In this context, several IPM techniques such as cultural, physical, biological, and chemical methods were elaborated, which could help to reduce the pest status below damaging levels.

“…But HLB is now endemic in Florida. Despite the frequency of psyllid testing and a known increase in insecticide resistance by D. citri (Chen et al 2022; Vázquez-García et al 2013; Naeem et al 2019; Rao et al 2014; Pardo et al 2018; Venkatesan et al 2022), relatively few papers have been published on population-level dynamics of C Las- D. citri infections in the field. A few studies have looked at D. citri-C Las titer and prevalence in different situations, including specific field sites, month to month changes, year to year trends, and differences between countries (Bové et al 1993; Wulff et al 2020; Capoor et al 1974; Coy and Stelinski 2015; Hall 2018; Manjunath et al 2008; Razi et al 2014; Tiwari et al 2010; Sétamou et al 2020; Ukuda-Hosokawa et al 2015; Walter et al 2012).…”

Huanglongbing (HLB, or citrus greening disease) affects all citrus varieties world-wide. In the USA, Asia, and South America the causal agent is “CandidatusLiberibacter asiaticus” (CLas), a phloem-limited, uncultured, alphaproteobacterium. The hemipteran insect vector,Diaphorina citri(Asian citrus psyllid) acquires and transmitsCLas in a circulative, propagative manner. In addition toCLas,D. citrihosts multiple symbiotic bacteria includingWolbachia(wDi). InD. citri, wDi has been sequenced and studied but specific roles inD. citribiology are unknown. Using well established quantitative PCR methods we measuredCLas titer inD. citricollected from four groves in central Florida with distinct HLB management strategies and tested whetherCLas and wDi titer were correlated in a sub-set of these insects. Grove site had the largest effect onCLas titer. Sex had no effect onCLas titer, while higher wDi titer was correlated withCLas-uninfected insects. Our results suggest that more directed follow-up research is necessary and important to clarify whether field management tactics influenceCLas titer inD. citriand to better understand gene-by-environment interactions amongD. citri, wDi andCLas. Now that millions of trees in Florida have been treated with injectable formulations of oxytetracycline, which is likely to decrease bacterial populations inD. citri, this study may represent the last biologically meaningful snapshot of grove-level vector-pathogen ecology in the state during the HLB epidemic.
