litchii, the developmental threshold temperatures ([degrees]C) and accumulated temperatures (degree-d) were: egg (14.3 [degrees]C, 66.7 degree-d), larva (14.8 [degrees]C, 31.7 degree-d), protonymph
(14.1 [degrees]C, 31.1 degree-d), deutonymph (13.0 [degrees]C, 36.1 degree-d), and entire generation (14.7 [degrees]C, 172.4 degree-d) (Table 3).
Paratypes: MEXICO: Veracruz: 1 [female], same data as holotype (CNAN-T1176), 1 [male], 1 protonymph
, 3 deutonymphs, 4 tritonymphs, same data as holotype (CNAN-T1177).
After the larvae eclosion, the duration, in days, of each mite developmental stage was observed: larvae, protonymph
, deutonymph, adult-egg period, and the longevity of males and females.
However, the protonymph
and deutonymph phases were similar at 25 and 30[degrees]C.
The life cycle of water mites is complex and includes the egg, larva, protonymph
, deutonymph, tritonymph, and adult.
The duration of the periods of larva (df= 107, t = 1.80, P = 0.07), protonymph
(df = 77, t = 0.40, P = 0.68), deutonymph (df = 66, t = 0.42, P = O.
The three nymphal instars are termed protonymph
, deutonymph, and tritonymph and can be easily recognized by the unique number of trichobothria of each stage .
The deutonymph or hypopus is a developmental instar of mites, and in H propus it is one of 5 juvenile stages including the prelarva, larva, protonymph
, deutonymph, and tritonymph.
The mean durations of larval, protonymph
, deutonymph of female and male stages were 1.10+-0.07, 0 1.02+-0.09 days; 1.10+-0.05, 0 1.07+-0.05 days; 1.03+-0.03, 0 0.96+-0.03 days respectively.
cocos comprised 3 inactive phases also viz., the first, second and third quiescent is between the larva and protonymph
and deutonymp, deutonymph and adult respectively.
Snake mites have a five-stage life cycle: egg, larva, protonymph
, deutonymph, and adult.
